can fly, many hundreds of mice will scarcely fuffice to fuppiy them with food. Owls caft up the bones, fur, or feathers of their prey, in form of fmali peilets, after they have devoured it, as hawks do. A gentleman, on grubbing up an old pollard afh that had been the habitation of owls for many generations, found at the bottom many bushels of this rejected stuff. Some owls, when they are fatisfied, hide the remainder of their meat like dogs.

ferruginous. Wings long; tail short, marked with dusky bars. Legs thick, covered to the very end of the toes with a clofe and full down of a teftaceous colour. Claws great, much hooked, and dusky. They have been fhot in Scotland and in Yorkshire. They inhabit inacceffible rocks and defert places; and prev on hares and feathered game. Their appearance in cities was deemed an unlucky omen; Rome itfelf once underwent a luftration becaufe one of them ftrayed into the capitol. The ancients held them in the utmost abhorrence; and thought them, like the fcreechowis, the meffengers of death. Pliny ftyles it bubo funebris, and noctis monftrum.

3. STRIX CAYENNENSIS, the spectacle owl of Cayenne, which is accurately defcribed by Dr Latham, is 21 inches in length: the upper parts of the body are of a reddish colour; the lower parts of a rufous white: the head and neck are white, and not fo full of feathers as thofe of owls gene-' rally are, and from this circumftance it appears not unlike a hawk: a large patch of dark brown furrounds each eye, giving the bird much the appearance of wearing spectacies; the legs are covered with feathers quite to the toes, and are of a yellowish colour. A fpecimen of this curious bird may be seen in the Leverian mufeum.

4. STRIX FLAMMEA, the common white owl. The elegant plumage of this bird makes amends for the uncouthnefs of its form: a circle of foft white feathers furround the eyes. The upper part of the body, the coverts, and fecondary feathers of the wings, are of a fine pale yeliow: on each tide of the thafts are two grey and two white fpots placed alternate: the exterior fides of the quill feathers are yellow; the interior white, marked on each fide with four black spots: the lower fide of the body is wholly white; the interior fides of the feathers of the tail are white; the exterior marked with fome obfcure dufky bars; the legs are feathered to the feet: the feet are covered with fhort hairs: the edge of the middle claw is ferrated. The ufual weight is 11 ounces; its length 14 inches; its breadth 3 feet.-This fpecies is almoft domeftic; inhabiting, for the greatest part of the year, barns, hay lofts, and other out-houses; and are as useful in clearing thofe places from mice as the congenial cat: towards twilight they quit their perch, and take a regular circuit round the fields, skimming along the ground in queft of field mice, and then return to their ufual reli tence: in the breeding feafon they take to the eaves of churches, holes in lofty buildings, or hollows of trees. During the time the young are in the neft, the male and female alternately fally out in quest of food, make their circuit, beat the fields with the regularity of a fpaniel, and drop instantly on their prey in the grafs. They feldom ftay out above five minutes; return with their prey in their claws; but as it is neceffary to fhift it into their bill, they always alight for that purpose on the roof, before they attempt to enter their neft. This fpecies do not hoot; but fnore and hifs in a violent manner; and while they fly along, will often scream moft tremendously. Their only food is mice. As the young of these birds keep their neft for a great length of time, and are fed even long after they

5. STRIX OTUS, the long-eared owl, is found, though not frequently, in the north of England, in Cheshire, and in Wales. Mr Haffelquift faw it alive in Cairo, and it is not unfrequent all over Egypt. Its weight, according to Dr Latham, is oz.; the length 14 inches and a half; the breadth 34; the irides are of a bright yellow; the bill black; the breast and belly are of a dull yellow, marked with flender brown ftrokes pointing downwards; the thighs and vent-feathers of the fame colour, but unfpotted. The back and coverts of the wings are varied with deep brown and yellow; the quill feathers of the fame colour, but near the ends of the outmoft is a broad bar of red; the tail is marked with dusky and reddish bars, but beneath appears afh-coloured; the horns or ears are about an inch long, and confift of fix feathers variegated with yellow and black; the feet are fea thered down to the claws.

6. STRIX PASSERINA, the little owl, is very rare in England; it is fometimes found in Yorkshire, Flintshire, and alfo near London : in fize it scarcely exceeds a thrush, though the fulness of its plumage makes it appear larger: the irides are of a light yellow; the bill of a paper colour; the fea thers that encircle the face are white tipt with black; the head brown, spotted with white; on the breaft is a mixture of white and brown; the belly is white, marked with a few brown spots; the tail of the fame colour with the back; in each feather barred with white; in each adorned with circular white fpots, placed oppofite to one another on both fides of the fhaft; the legs and feet are covered with feathers down to the claws.— The Italians make use of this owl to decoy fmall birds to the limed twig; the method of which is exhibited in Olina's Uccelliera, p. 65. Mr Stuart, author of the Antiquities of Athens, informed Mr Pennant, that this fpecies of owi was very common in Attica; that they were birds of passage, and appeared there in the beginning of April in great numbers; that they bred there; and that they retired at the fame time as the ftorks, whose arrival they a little preceded.

7. STRIX STRIDULA, the tawny owl. The fe male of this fpecies weighs 19 ounces; the length is 15 inches; the breadth 2 feet 8 inches; the irides are dusky; the ears in this, as in ali owls, very large; and their fenfe of hearing very exqui fite. The colour of this kind is fufficient to di tinguish it from every other: that of the back, head, coverts of the wings, and on the fcapular feathers, being a fine tawny red, elegantly fpotted and powdered with the black or dufky spots of various fizes: on the coverts of the wings, and on the fcapulars are several large white fpots: the coverts of the tail are tawny, and quite free from any marks: the tail is variously blotched, barred

and

and spotted with pale red and black; in the two middle feathers the red predominates; the breaft and belly are yellowish, mixed with white, and marked with narrow black strokes pointing down wards: the legs are covered with feathers down to the toes.-This is a hardier species than the FLAMMEA; and the young will feed on any dead thing, whereas thofe of the white owl must have a conftant fupply of fresh meat. It is the ftrix of Aldrovandus, and what we call the fcreech owl, or Lich Owl, to which the folly of fuperftition had given the power of prefaging death by its cries. The ancients believed that it fucked the blood of young children: a fact some think not incredible; for Haffelquift defcribes a species found in Syria, which frequently in the evening flies in at the windows, and deftroys the helpless infant. See Ovid. Faft. vi. 135.

8. STRIX ULULA, the brown owl, agrees with
the former in its marks; differing only in the co-
lours in this, the head, wings, and back, are of a
deep brown, spotted with black in the fame man-
ner as the former; the coverts of the wings and
the scapulars are adorned with fimilar white fpots: 4. The found of the clock.-
the exterior edges of the four firit quill feathers in
both are ferrated the breaft in this is of a very
pale ash-colour mixed with tawny, and marked
with oblong jagged spots: the feet too are fea-
thered down to the very claws: the circle round
the face is afh-coloured, spotted with brown.-
Both these species inhabit woods, where they re-
fide the whole day: in the night they are very
clamorous; and when they hoot, their throats are
inflated to the fize of an hen's egg. In the dufk
they approach our dwellings; and will frequent-
ly enter pigeon-houses, and make great havoc in
them. They deftroy numbers of little leverets,
as appears by the legs frequently found in their
nefts. They alfo kill abundance of moles, and
fkin them with as much dexterity as a cook does
a rabbit. They build in hollow trees or ruined
edifices; lay four eggs, of an elliptic form, and of
a whitish colour.

STROMA, an island of Scotland, in the Pentland Frith, 3 miles from the coaft of Caithnefs; about one mile long, and half a mile broad. It has about 170 inhabitants, and rents at 120 l. fterling. The property of this inland was once difputed, between the Earls of Orkney and Caithnefs, and decided not by a duel, or battie, but by an experiment in natural hiftory. Some venomous animals were brought to the island, and as they continued to live in it, which they do not when tranfported to the Orkneys, Stroma was adjudged to belong to Caithnefs. It is very fertile in corn, but the crops are fometimes damaged by the pray from the fea. The rocks are very high all around the coaft, but especially on the W. fide; where the fury of the waves which beat against them during a storm from the W. exceeds all defcription.

(1.) STRONSA, or One of the Orkney (1.) STRONSAY, Islands, 7 miles long, and about as bread, but so much indented by long and narrow bays, that no place in the island is 14 miles from the fea. The coaft is partly flat, partly rocky; and has 2 remarkable promontories; viz. BORROW-HEAD on the SE. and Rothesholm, or Rodnumhead on the SW. There are 3 fandy bays, which do not afford fafe anchorage, on account of the numerous funk rocks with which they abound; but these rocks are a chief fource of emolument to the inhabitants, as they abcund with fea ware, of which about 300 tons of kelp are made annually. There are, however, 2 fafe harbours in the island; viz. Ling Bay on the W. fheltered by the holm of Ling, and PAPA SOUND. The furface of Stronfay is rugged, a ridge of hills running its whole length from N. to S. The foil is a dry friable, blackish earth, on a clay bottom mixed with small ftones. The pafture on the hills feeds about 3000 sheep, 500 horfes, goo black cattle, and 3co fwine. A vein of lead was difcovered many years ago on the W. coaft, but it has never been wrought. The population, in 1792, was about 900. There are ruins of 4 ancient chapels. There is a minerai fpring called the Well of Kildingue, which abourds with carbonic acid gas; and which was anciently fo much esteemed as a medicine that the nobility and gentry of Denmark came over to drink it.

(3.) STRONTIAN, in mineralogy, a new fpecies of earth lately difcovered at Strontian. Dr Kirwan fays, the first information he received of it was from Dr Crawford in 1790. In the Miners Journal for Feb. 1791 a good defeription of its external appearance, with fome account of its chemical properties, was published from the obfervations of Mr Sulzer. Its external characters are these; Its colour is whitish or light green; its lufter common; its tranfparency intermediate between the femitransparent and opaque; its frac ture ftriated, prefenting oblong distinct concre tions, fomewhat uneven and bent; its hardness moderate, being eafily fratched, but not scraped. It is very brittle; and its specific gravity from 34 to 3644. For a farther account of na chemical qualities, fee MINERALOGY, Part II, Chap III, II. and Thomson's Chem. Voi. I. p. 422, &c. It is not affected by the fulphuric acid; but when diluted, r0.000 parts of it will diffolve one of frontian. Diluted nitric acid diffolves it rapidly. The muriatic acid, whether diluted or oxydated, diffolves it in a fimilar manner. It has a ftrong resemblance to barytes, but effenfially dif fers from it. Its fpecific gravity is lefs; it parts with its carbonic acid when urged by heat fomewhat more readily, and without fuffering fufion; when calcined, it imbibes moisture with vastly greater avidity, swelling and cracking with more heat and noife. Strontian diffolves much more abundantly in hot water than barytes; and the form of the crystals of thefe pure earths is very diffiniiar. The compounds frontian differ from those of barytes. This earth, united to nitric and muriatic acid, forms falts that fuffer changes from exposure to air, which do not happen to the nitrate and muriate of barytes. They are likewife much more foluble in water, and have cryftals of a peculiar figure. The combinations of frontian with acids are not, like those of barytes, decompofed by pruffiate of lime or of potath. Strontian and its compounds tinge flame, which barytes does not. Lastly, thefe earths di'agree in the order of their attractions. It is alfo diftinguifhed from lime ftone: for it is much heavier, and retains its fixed air with more obftinacy in the fire. The incomparably greater folubility of the pure earth in hot than in cold water, and the cryftal-line from it affumes, fufficiently distinguish it from lime, which the difpofition of the nitrate and muriate to cryftallize no lefs tends to do. 100 parts of ftrontian are compofed of 6121 of earth, 30°20 of carbonic acid, and 8'59 of water.
