Its wood is remarkably hard, and therefore valuable to turners for screws or cog-wheels and to mathematical instrument-makers; for rulers, gauging-sticks, &c.

3. The hybrida (Pyrus hybrida of Dr. SMITH), BASTARD MOUN- TAIN ASH, or BASTARD SERVICE, is found principally on mountains, where it flowers in the month of May. This tree forms a singular variety of the two preceding spe- cies, and consequently partakes of their united properties. Its wood, however, is softer than that of the true Service-tree; and, though af- fording good fuel, its charcoal is greatly inferior to that obtained from the latter:-its berries are sweeter, and preferably eaten by birds.

The Service-tree is cultivated in Britain, principally as an ornament for diversifying extensive planta- tions; as it grows to the height of 40 feet. It is propagated by sow- ing the seed, a short time after the fruit is ripe, in pots, which must be sheltered during the winter; and, when the spring advances, it will be proper to plunge them in hot-beds, and to water them fre- quently, duting dry weather. To- wards the middle of October, the young plants may be removed to a warm spot of light soil, and placed one foot apart from each other, in rows two feet asunder. Here they should remain for three or four years; at the expiration of which, they ought to be transplanted to the place appropriated to their growth.

SETON, in surgery, a kind of issue, or artificial ulcer, produced by passing the seton-needle through any of the larger muscles, and in- ntroducing a cord made of cotton or silk thread; in order to effect the discharge of superfluous, or mor- bid, matter,

Instead of describing the parti- culars; relative to this chirurgical operation, we shall merely observe, that setous occasionally prove use- ful remedies; especially where the body abounds with humburs: hence they are frequently made in the back of the neck, for diseases of the eyes; or between two of the ribs, in affections of the chest. As, however, a seton occasions a great degree of pain and irritation, it is not applicable to weakly and delicate persons, with whom the common issues generally agree. Nevertheless, either of these re- medies are attended with similar effects; and the former, in parti- culur, has been strongly recom- mended in ulcerations of the lungs and chest ; nay, the late Mr. Pott was the first who successfully em- ployed this expedient in various cases of hydrocele,

SETONS, in farriery, are oc- casionally applied to various parts of a horse's body, for the purpose of discharging! matter from deep seated tumors of abscesses.

Setons are introduced by means of long, thin needles, dart-shaped at the point, and armed with a suitable cord. The size of the in- strument, as well as the thread, depends on that of the part affect-
