234&#93; 254] TOU commrnded, as peifeftly fafe, by a •ktlful young surgeon in the me- tropolis. After providing a hard roll of linen bandage, about 4 or 5 inches in width, and 3 in thick- ness, as likewise a smooth board, 9 inches in length, 3 in width, and I of an inch in tliickness, with the sides and ends squared at right angles j ..the roller is to be placed mid-way in the bam on the under sides of the ktiee-joint ; the leg be- ing extended in a straight line. Next, the piece of board must be laid over the roller, which is to aft as a pad of compression on the popliteal artery that extends from ihc ham over the hollow of the knee ; the length of the board run- ning cross- ways, and projefting on the knee-joint on each side. Now, the girth of the tourniquet is to go roimd the knee above (not upon) the knee-pan, and over the pro- jefting ends of the board. The screw should rest at the upper part of the limb and the knee-pan, hav- ing also a pad interposed between it and the skin. By this mode of compressing the popliteal artery, an important advantage is gained j because it allows the arterial circu- lation to proceed uninterrupted through the lateral branching ves- sels } the large superficial veins are not di^jturbed ; and the limb re- mains in the same state as if the artery alone had been tied. — In all casesof profusehemorrhages, when there is a chance of saving the limb, such method of applying the common tourniquet, will be pre- ferable to the usual manner, by which the circulation of the blood is entirely stopped. Farther, in gun-shot wounds, compound frac- tures, and secondary bleedings af- ter amputation below the kiiee, the pradice here suggested will gene- TR A rally be attended with the dcsircdi eiFea. Having thus enlarged upon 4 subjeft, which materially relates to the safety of evei y individual, we shall only add (as supplementary to the article Styptic), that in ac- cidental injuries, or wounds at- tended with profuse bleeding: from large blood-vessels, we are not ac- quainted with a more simple and effectual remedy tlian the Powder of Gum Arabic. This mild appli- cation to the orifice oi the vein, or artery, sj>eedily forms an incrusta- tion around the part alleded j especially if it be imuiediatcly strewed over the spot from which the blood Lssues ; and if the con- tiguous muscles be at the same time gently compressed, till a pro- per bandage, roller, or tourniquet, can be procured. TOWER-MUSTARD, the Smooth, or Tower-wort, Tur- rilis glabra, L. is an indigeno^s plant growing in gravelly mea- dows, pastures, and pits, where the stalks attain the height of two feet, and the greenish- white, large flowers appear in May and June.— • ITie taste of this vegetable resera- 1 bles that of cresses ; and, aflfording wholesome food for cattle, we con- ceive it deserves the attention of cultivators, in the northern parts of the island, which abound witl^ dry, stony lands and pastures. Farther, the flowers of the tower- wort supply the industrious bee with wax and honey. TRAGACANTH, agumobtained from the Astragalus Tragacantha, L. a thorny bush, growing in tl)e Levant, in Candia, on Mounts Olympus, Ida, andiEtna : it pays, on itiiportation, a duty of 3jd. per lb.
