16. The malignant carbuncle, or charbon, of animals is characterized by the appearance of a voluminous uncircumscribed tumour, which yields to pressure, crepitates like emphysema, and exhales a peculiar putrid odour. The centre of the swelling is black, as if carbonized, and the circumference is infiltrated with a brownish or yellowish fluid, and distended by a very fetid gas. After death the substance of the heart is softened, and its external surface ecchymosed in the course of the blood-vessels. The blood in the heart and large vessels is generally fluid. In the veins it is very black, sometimes containing clots of a black or yellowish colour. The lungs are covered by small ecchymoses, which are also seen penetrating their substance. The stomach and intestines present black san

Inter; and that the true anthracion or malignant addition to the destruction of the integuments pustule is generally infected by the morbid fluids and adjoining cellular tissue of the affected part, of cattle, &c., and especially by the malignant marks of congestive inflammation with ecchy-carbuncle of animals, or that attacking sheep moses have been observed in the lungs, liver, and other woolly and hairy animals, and which spleen, and digestive canal. M. VIRICEL States, I shall briefly describe. that he found malignant pustules in the colon; and M. LAMBERT says, that the gelatinous serous deposites always found in the adjoining subcutaneous cellular tissue is occasionally also found in the cellular tissue of the mediastinum. A quantity of sanguinolent serum is commonly effused into the serous cavities. The several tissues are more or less softened, and the viscera and blood present the same changes as are found in the malignant carbuncle of animals. 14. III. DIAGNOSIS.-On its first appearance the malignant pustule may be mistaken for the bite of an insect; but it wants the minute central yellowish point of an insect bite, and soon presents the painful indurated base, and the sanious vesicle with which malignant pustule commences, and which, with the diffuse or erisypelatous and emphysematous-looking inflam-guineous ecchymoses, of various sizes, between mation surrounding it, also distinguishes it from furuncle, carbuncle, or anthrax. Malignant pustule in some instances, however, can hardly be distinguished from the more gangrenous form of carbuncle (see art. FURUNCULAR DISEASES, &C., 14, et seq.); and it is most probable that the one affection runs into the other, those cases of sporadic anthracion which have not been traced to contagion being only instances of very | severe carbuncle, the local and constitutional characters of which they have certainly possessed.

15. On the other hand, anthracion may be confounded with phlegmonous or gangrenous erysipelas, and with the gangrenous or sphacelating ulceration of the cheeks, and labia majora vulvæ met with in children, or even with the bubo or carbuncle of plague; and certainly cases of these occasionally very closely resemble anthracion, and if they be not seen at an early stage, or at their commencement, the diagnosis will be difficult, if not impossible in some instances. These, however, do not present the sanious vesicle or the puriform pustule with which anthracion originates; and the gangrenous affection of the cheeks of children commences in the inside of the mouth, and extends to the skin. From pestilential carbuncle and bubo anthracion is distinguished by the absence of the symptoms characterizing plague, and by the several circumstances attending either the one or the other. Cases of anthracion, however, are not so readily distinguished, as M. RAYER supposes, from the carbuncles in cases of sporadic or scattered plague. Indeed, he endeavours to draw distinction, but conceals close resemblances between this malady and those which are very closely allied to it, if they be not altogether identical with it. I would, however, infer, that the sporadic or uncontagious cases of malignant pustule, or the affection described as such, are severe cases of carbuncle (see FuRUNCULOUS DISEASES, 14, et seq.); that the malignant pustule or anthracion, caused by the contact of a poisonous or morbid animal matter, consists of local changes which closely resemble the worst cases of carbuncle, and of a constitutional disturbance often of a more intense

the inner coats and under the peritoneum, and variously distributed in different parts of the canal. The liver and spleen are gorged with dark blood. The nervous system is said not to offer any change.

17. The same changes, local and visceral, which are found in the malignant carbuncle of animals are also found in the blood, heart, lungs, digestive organs, and other viscera in cases of fatal malignant pustule in the human subject; and, moreover, the discharge from the disease of the brute produces the same malady in man-malignant pustule or anthracion. The identity of both these diseases cannot, therefore, be disputed, although the spontaneous or sporadic appearance of anthracion in man may be disputed, or may want confirmation.

18. IV. PROGNOSIS.-The first variety may recover of itself, the gangrene terminating spontaneously, or being readily arrested by treatment. The second is much more serious, but it will generally be cured by the prompt and energetic use of caustics. The third variety is generally mortal, and it may end fatally in twentyfour or forty-eight hours from its appearance. The danger is always greater from the second variety, when it attacks the face, head, or neck, than when it affects the extremities. It is also aggravated by extremes of temperature.

19. V. TREATMENT.-M. RAYER states, that as soon as the existence of anthracion is ascertained, the part must be deeply scarified and extensively cauterized. To be effectual, the incisions should extend to all the gangrenous parts, but not beyond them. The vesications on the surface ought to be immediately opened and the fluid absorbed, and the denuded surface covered with a dossil of lint dipped in the liquid muriate of antimony, or with a small fragment of caustic potash, kept in its place by a strip of plaster and a bandage. Five or six hours afterward this application may be removed, and the eschar covered with lint spread with the unguentum resinorum, or some other salve of a similar kind. Instead of the caustics advised by M. RAYER, I would recommend the nitric acid to be freely applied, and to be followed by the usual dressings and the internal treatment pre

scribed for gangrenous inflammation of the cellular tissue and for carbuncle. (See articles CELLULAR TISSUE, ◊ 35, et seq., and FURUNCULOUS DISEASES, 20, et seq.)

20. Next day, if it be found that no vesicular areola has been formed around the eschar, and if the patient complains of but little pain, without smarting or pungent heat, it may be inferred that the cautery has included the whole of the disease. If, on the contrary, a hard and deep-seated tumour has appeared around the primary seat of the malady, and symptoms of phlegmous-erysipelatous inflammation are present, the caustic must be applied again, having first removed the gangrenous parts, after dividing them by a crucial incision. This procedure is also necessary when the slough, which forms the centre of the swelling, has already become hard and impermeable like a piece of leather; for it must be removed to admit of the action of the caustic being exerted on parts not yet sphacelated, after which they are to be covered with a stimulating poultice.

it is liable to the objections which may be urged against nosological descriptions, namely, that it represents merely a single type or phase of the disease; a single and distinctly characterized form, without any notice of the modifications and gradations which ally it to other disorders of the digestive organs. I shall first describe this affection nearly in the terms used by Dr. CULLEN, and afterward notice such variations as have fallen under my observation.

3. I. SYMPTOMS.-Pyrosis appears most commonly in persons under middle age, but seldom before the age of puberty. When it has once taken place, it is apt to recur occasionally for a long time after; but it seldom appears in persons far advanced in life. It affects both sexes, but more frequently the female. The fits of the disease usually come on in the morning and forenoon, when the stomach is empty. The first symptom is pain at the pit of the stomach, with a sense of constriction, as if the stomach were drawn towards the back. The pain is increased by raising the body erect, and is alleviated by bending forward. It is often severe, and after continuing for some time it is followed by an eructation of a thin, watery, limpid, or nearly clear and often ropy fluid in considerable quantity. This fluid is generally insipid, but it is sometimes more or less acid. The eructation is for some time repeated frequently, and does not immediately give relief to the pain; but it does so at length, and terminates the attack.

gestion. I have seen it also unattended and not preceded by any actual pain at the pit of the stomach, but by slight uneasiness only in that situation; and in more than one case the patient complained of the great coldness of the fluid thus ejected. The pain is quite different from that of cardialgia, or heart-burn, when the fluid brought up is abundant, insipid, ropy, and

colourless; but when it closely resembles cardialgia, the sensation of constriction, with bending forward of the trunk, is not present, and the fluid ejected is often acid, and less abundant than when the pain is of the constrictive character above described. In no case is the dis-sea or vomiting, and as this discharge may be ease attended by fever, or by nausea or retchings. The fluid is always regurgitated or eructated by a similar inverted action of the esophagus to that producing rumination. It has appeared to me, during a careful observation of some cases, that the constrictive pain, as well as the ejection of the fluid, partly may be referred to the diaphragm.

7. III. PROGNOSIS.-Having once taken place, pyrosis is very apt to recur, and it is often very difficult to cure; but I have not met with an instance of it having passed into serious or structural disease, or been attended with danger. I am intimately acquainted with a gen

Pyrosis cannot be confounded with simple gastrodynia, inasmuch as the former is attended by the copious discharge of a peculiar fluid, without nauabundant although the pain may be very slight, gastrodynia being only a symptom of several gastric diseases. Dr. WEST states, without, however, adducing his authority, that the secretion of true water-brash is composed of water, albumen, and a trace of sodaic salt, with an excess of soda; and that, when it is acid, this property is owing to the muriatic and acetic 5.

Besides, it could hardly be expected that so large a quantity of fluid could be furnished by the pancreas in so short a time as during a fit of pyrosis. I am not aware of any instance in which organic disease of the pancreas has followed pyrosis, or in which such disease had taken place in a patient who had been at any previous period the subject of this affection. Dr. SEYMOUR adduces a case in which organic change in the liver followed pyrosis; but the cases which I have observed have not been associated with any organic change, excepting in one instance, although various functional disorders have often been present. It is not unusual, especially in northern countries, where pyrosis is most prev-in females than in males, and in the unmarried alent, to observe it in the course of pregnancy, and in both married and unmarried females, complicated with leucorrhoea. I have seen it in one instance associated with disease of the ovaria, and frequently in these countries with chronic rheumatism.

Persons who are subject to it generally are able to pursue their avocations without much inconvenience; and often continue free from it for a considerable time, without any very obvious cause, and then are attacked, owing either to some error of diet, or exposure to cold and moisture. When the complaint is prolonged, the patient frequently becomes pale, considerably emaciated, and debilitated; and when it is protracted in females, scanty, or difficult, or painful menstruation is a common consequence. 8. IV. CAUSES.-A. Pyrosis is more frequent

than in the married. It may occur at any age, after six or seven years, but it is most common after puberty and until far-advanced age. It is so prevalent in some countries as to be considered endemic in thein, especially in Sweden, Norway, Lapland, Scotland, and the Isles, 6. II. DIAGNOSIS.-Pyrosis is readily distin- &c.

The eructations which often accompany cardialgia, or other forms of indiges-siderable quantity, and of dried fish-both the tion, are usually observed during the progress of digestion; the fluid eructated being generally in small quantity, and acrid, always discoloured, and often furnishing indications of the indigestible matters. When the fluid of pyrosis is at all acid or acrid, these properties are much less marked than in cardialgia or the allied states of dyspepsia (see art. INDIGESTION, 13, 14); it furnishes no indications of undigested matters, and is thrown up from a stomach which

Pyrosis is certainly, also, much more frequent in cold and humid climates than in temperate, dry, or warm countries, and among the poor and ill-clothed than among the wealthier classes; although the latter are not exempt in these climates. LINNEUS states that nearly one half of the population, men and women, living near the mountains in Lapland, were in his time the subject

of this complaint, and that in some it endured through their entire lives.

C. The nature of this complaint has been readily devised. Indeed, this view, as well as much discussed. Pyrosis has been viewed as the treatment, or, rather, the no treatment, a form of indigestion, and it is probably allied founded on it, is not infrequently adopted by to indigestion in many instances as it occurs persons subject to this complaint; for they genin this and other temperate countries; but in erally endeavour to prevent long fasting, rather northern countries I have seen instances of it than to cure the attack by eating, when the pain attended by powerful and rapid digestion.

These erful digestion, and who live on food requiring strong digestive and assimilative powers, I inferred an abundant secretion of this juice, which would not infrequently be continued to be secreted in excess, especially in circumstances favouring the determination of blood to the digestive viscera, and in the very circumstances by which I have observed a fit of pyrosis to be produced, although there existed no food in the stomach to excite the secretion of the gas- 12.

According to this view, the frequent discharge of secretions, so instrumental as they are in the assimilative processes, must necessarily be followed, in protracted cases, by pallor, emaciation, anæmia, and the other complications and consequences mentioned above (§ 5).

substances, by allaying the morbid irritation of the nerves of the organ, diminish or prevent the excessive secretion of the gastric fluids causing the disorder; but, as long as the diet is persisted in that causes the complaint, the continued use of these substances is required to prevent a recurrence of the disorder, and thus the remedy often becomes as great an evil as the disease itself.

er; still they are distinct. The pain of pyrosis is different from that of cardialgia, or of the more usual painful affections of the stomach termed gastrodynia, or gastralgia, and it may be so slight as to amount only to uneasiness. The matters brought up from the stomach are either not acid or very slightly so, are unmixed with undigested matters, are clear and colourless, are so abundant, and are so peculiar, even as respects their low temperature, as to constitute the chief feature of the complaint. The substances ejected either by eructations

rancid; consist partly of, or contain, undigesters subject to pyrosis; and most probably, if
ed articles; and proceed from an unloaded, or
a partially loaded, as well as irritated stomach.
They are often the products of excess, or are
consequent upon errors of diet, or are owing to
a weakened or an irritated state of the stomach.
But pyrosis occurs only when the stomach is
empty, after the usual diet, taken in very mod-
erate or even in insufficient quantity, and the
fluids, by which it is chiefly characterized, are
regurgitated without nausea or retchings, and
always unmixed with undigested matters, as
already stated (§ 6).

it had been long or often used, in the doses (20
grains) to which he allowed it to be carried,
the remedy would have been soon found worse
than the disease. (See article PoISONS,
et seq.) Dr. BAILLIE prescribed a drachm of
the tincture of benzoin suspended by mucilage,
and Dr. PEMBERTON, ten grains of powdered
kino with half a grain of opium every fourth
hour at the commencement of the attack; or
a bolus, consisting of six grains of alum with
two or three grains of the soap and opium pill,
the bowels being kept in an open state by rhu-
barb or other aperients. There can be no
doubt of the occasional efficacy of these and
of other remedies, especially those prescribed
for the more painful forms of dyspepsia (see ar-
ticles INDIGESTION, 49, et seq.; and STOMACH,
painful affections of), when they are aided by
diet and warm clothing; but without such aids
they will often fail. Change to digestible and
wholesome food, due promotion of the cutane-
ous functions, and an open state of the bowels
by means of stomachic or tonic aperients, are
most deserving confidence, both for the cure
and for the prevention of attacks of this com-
plaint, which if otherwise treated will always
prove most obstinate.

[Pulverized charcoal, blended with carbonate of magnesia and united with ginger, has been successfully given (since 1812) in various forms of gastralgia and pyrosis, according to Dr. FRANCIS.]

13. States of disorder quite distinct in themselves, and different in their natures and characters, have thus been confounded with each other; and substances which have been found of service in one or more of these have been recommended as cures for pyrosis, although they are either altogether inappropriate, or only temporarily beneficial. Indeed, unless the chief causes of the disorder be removed-unless many of those who are the subjects of pyrosis live on more nutritious and digestible food, and are better protected from cold and wet than usually fall to their lots-no permanent advantage can be expected from treatment. Most of the remedies which have been prescribed for pyrosis, and have been said to remove it, merely alleviate the attack, but seldom succeed in preventing a recurrence of it. These medicines are generally appropriate in cardialgia, and in most cases of indigestion which are attended by acidity and flatulence, and by the eructation of fluid matters, more or less acid, or acrid, containing undigested, or partially digested substances. But these cases are not cases of pyrosis; and although these medicines are sometimes useful in this latter affection, still they are not permanently beneficial unless they be aided by change of diet, especially by an improved diet. Among the remedies thus recommended, thoset. xlvi., p. 341.-B. Parr, Lond. Med. Dict., 4to. London, usually prescribed for the severer forms of indigestion hold prominent places, especially absorbents, as lime-water with milk; soap with small doses of opium; magnesia with various antispasmodics, and narcotics (RANOE, &C.); the oxyde of bismuth, with aloes or henbane (ODIER, MARCET, &c.); and ammonia in bitter infusions. As pyrosis was thus generally viewed as a form of indigestion, and not as an affection, caused by the nature of the diet and by the influence of cold and humidity upon the surface and extremities, and independent of defective digestive power, numerous other digestive aids were prescribed for its cure; and among these I may mention, as being sometimes beneficial, the mineral acids, particularly HALLER'S OF MYNSYCHT's sulphuric acid-the acidum sulphuricum aromaticum-the preparations of iron, and the balsams, especially the Peruvian balsam. Bitter almonds, with ammonia and the preparations of angelica root, were much praised by several German writers; and inspissated ox-gall,* with asafoetida and soap,
