The class-book of anatomy : designed for schools, explanatory of the first principles of human mechanism, as the basis of physical education . s wants. On the sides of all the arteries, millions ofvessels, infinitely fine, more nearly like the down on apeach than arteries, conduct a circulation. This tissue ornet work of miniature arteries, is the vasa , the arteries are made up of several coats, as thoughone tube were thrust into another, — which are muscu-lar and membraneous, according to their importance. As they recede from the heart, the tendency is to keepsubdividing, to supply every possible part, — hence, ulti-mately, they become too small to be seen. Between thesepoints, and the commencement of the veins, is an inter-mediate set of real or imaginary vessels, the capillaries,through which the blood must pass to reach the is the monstrous size of the aorta in a whale thatthe whizzing velocity of the blood, at each systole, isaudible to the harpooners: with the stethoscope, quite amodern invention, the rush of the blood may be heard inour own species.

It is utterly impossible aswell as unprofitable, in an el-ementary work of this kind,intended for youth, to p?ctureevery vessel; but we weredesirous of displaying the ar-teries of the arm and palm ofthe hand, on account of thebeauty and great importanceof the structure. What isseen in this drawing, exists inevery living arm. Over thebend of the elbow, a mereweb lies between the greatartery and vein. The vein istaken away, but it will showhow dangerous it is to bleedthe vein, at this point, on ac-count of the nearness of theartery, which is liable to bewounded by the point of thelancet. A knowledge of thisfact, should deter every onefrom employing surgeons inwhom they have not the mostimplicit confidence, that theyunderstand anatomy, a, b, e,d, e, f, g, h, k, mark thebranches of the brae h ial arterya, as they are, in rel
