One of the most curious examples of the fallacy of popular belief and the uncertainty of asserted facts in medical experience is to be found in the history of the UNGUENTUM ARMARIUM, or WEAPON OINTMENT.

Fabricius Hildanus, whose name is familiar to every surgical scholar, and Lord Bacon, who frequently dipped a little into medicine, are my principal authorities for the few circumstances I shall mention regarding it. The Weapon Ointment was a preparation used for the healing of wounds, but instead of its being applied to them, the injured part was washed and bandaged, and the weapon with which the wound was inflicted was carefully anointed with the unguent. Empirics, ignorant barbers, and men of that sort, are said to have especially employed it. Still there were not wanting some among the more respectable members of the medical profession who supported its claims. The composition of this ointment was complicated, in the different formulæ given by different authorities; but some substances addressed to the imagination, rather than the wound or weapon, entered into all. Such were portions of mummy, of human blood, and of moss from the skull of a thief hung in chains.

Hildanus was a wise and learned man, one of the best surgeons of his time. He was fully aware that a part of the real secret of the Unguentum Armarium consisted in the washing and bandaging the wound and then letting it alone. But he could not resist the solemn assertions respecting its efficacy; he gave way before the outery of facts, and therefore, instead of denying all their pretensions, he admitted and tried to account for them upon supernatural grounds. As the virtue of those applications, he says, which

are made to the weapon cannot reach the wound, and as they can produce no effect without contact, it follows, of necessity, that the Devil must have a hand in the business; and as he is by far the most longheaded and experienced of practitioners, he cannot find this a matter of any great difficulty. Hildanus himself reports, in detail, the case of a lady who had received a moderate wound, for which the Unguentum Armarium was employed without the slightest Yet instead of receiving this flat case of failure as any evidence against the remedy, he accounts for its not succeeding by the devout character of the lady, and her freedom from that superstitious and over-imaginative tendency which the Devil requires in those who are to be benefited by his devices.

use.

Lord Bacon speaks of the Weapon Ointment, in his Natural History, as having in its favor the testimony of men of credit, though, in his own language, he himself "as yet is not fully inclined to believe it." His remarks upon the asserted facts respecting it show a mixture of wise suspicion and partial belief. He does not like the precise directions given as to the circumstances under which the animals from which some of the materials were obtained were to be killed; for he thought it looked like a provision for an excuse in case of failure, by laying the fault to the omission of some of these circumstances. But he likes well that "they do not observe the confecting of the Ointment under any certain constellation ; which is commonly the excuse of magical medicines, when they fail, that they were not made under a fit figure of heaven." It was pretended that if the

This was a mistake, however, since the two recipes given by Hildanus are both very explicit as to the aspect of the heavens required for different stages of the process.

offending weapon could not be had, it would serve the purpose to anoint a wooden one made like it. "This," says Bacon, "I should doubt to be a device to keep this strange form of cure in request and use; because many times you cannot come by the weapon itself." And in closing his remarks on the statements of the advocates of the ointment, he says, "Lastly, it will cure a beast as well as a man, which I like best of all the rest, because it subjecteth the matter to an easy trial." It is worth remembering, that more than two hundred years ago, when an absurd and fantastic remedy was asserted to possess wonderful power, and when sensible persons ascribed its pretended influence to imagination, it was boldly answered that the cure took place when the wounded party did not know of the application made to the weapon, and even when a brute animal was the subject of the experiment, and that this assertion, lie as we all know it was, came in such a shape as to shake the incredulity of the keenest thinker of his time. The very same assertion has been since repeated in favor of Perkinism, and, since that, of Homœopathy.

The same essential idea as that of the Weapon Ointment reproduced itself in the still more famous SYMPATHETIC POWDER. This Powder was said to have the faculty, if applied to the blood-stained garments of a wounded person, to cure his injuries, even though he were at a great distance at the time. A friar, returning from the East, brought the recipe to Europe somewhat before the middle of the seventeenth century. The Grand Duke of Florence, in which city the friar was residing, heard of his cures, and tried, but without success, to obtain his secret. Sir Kenelm Digby, an Englishman well known to

fame, was fortunate enough to do him a favor, which wrought upon his feelings and induced him to impart to his benefactor the composition of his extraordinary Powder. This English knight was at different periods of his life an admiral, a theologian, a critic, a metaphysician, a politician, and a disciple of Alchemy. As is not unfrequent with versatile and inflammable people, he caught fire at the first spark of a new medical discovery, and no sooner got home to England than he began to spread the conflagration.

"An opportunity soon offered itself to try the powers of the famous powder. Mr. J. Howell, having been wounded in endeavoring to part two of his friends who were fighting a duel, submitted himself to a trial of the Sympathetic Powder. Four days after he received his wounds, Sir Kenelm dipped one of Mr. Howell's garters in a solution of the Powder, and immediately, it is said, the wounds, which were very painful, grew easy, although the patient, who was conversing in a corner of the chamber, had not the least idea of what was doing with his garter. He then returned home, leaving his garter in the hands of Sir Kenelm, who had hung it up to dry, when Mr. Howell sent his servant in a great hurry to tell him that his wounds were paining him horribly; the garter was therefore replaced in the solution of the Powder, and the patient got well after five or six days of its continued immersion.”

King James First, his son Charles the First, the Duke of Buckingham, then prime minister, and all the principal personages of the time, were cognizant of this fact; and James himself, being curious to know the secret of this remedy, asked it of Sir Kenelm, who revealed it to him, and his Majesty had

the opportunity of making several trials of its efficacy, which all succeeded in a surprising manner."

The king's physician, Dr. Mayerne, was made master of the secret, which he carried to France and communicated to the Duke of Mayenne, who performed many cures by means of it, and taught it to his surgeon, who, after the Duke's death, sold it to many distinguished persons, by whose agency it soon ceased to be a secret. What was this wonderful substance which so astonished kings, princes, dukes, knights, and doctors? Nothing but powdered blue vitriol. But it was made to undergo several processes that conferred on it extraordinary virtues. Twice or thrice it was to be dissolved, filtered, and crystallized. The crystals were to be laid in the sun during the months of June, July, and August, taking care to turn them carefully that all should be exposed. Then they were to be powdered, triturated, and again exposed to the sun, again reduced to a very fine powder, and secured in a vessel, while hot, from the sunshine. If there seem anything remarkable in the fact of such astonishing properties being developed by this process, it must be from our short-sightedness, for common salt and charcoal develop powers quite as marvellous after a certain number of thumps, stirs, and shakes, from the hands of modern workers of miracles. In fact the Unguentum Armarium and Sympathetic Powder resemble some more recent prescriptions; the latter consisting in an infinite dilution of the common dose in which remedies are given, and the two former in an infinite dilution of the common distance at which they are applied.
