    rI he coronary arteries of the heart sometimes differ in their number and distribution from what 1 have here represented. Thebesius3 has ob- served only one, though a large trunk, arising from the aorta, and immediately dividing into two branches. Winslow13 and FioratF have both noticed three coronary arteries. The following figures exhibit the principal varieties of the aorta, and of the branches arising from its arch : for, the branches of the aorta do not always originate in the same manner ; nor are they distributed in all bodies after the same law, even although they do arise in the usual way. I have here laid down those varieties in the origin and course of the trunks arising from the arch of the aorta, which I have either myself observed,d or seen depicted and described in the works of other anatomists. Figure III. Represents the most uncommon variation of the aorta, which Klinz6 observed in the body of a soldier twenty years of age. The aorta forms no arch, but after emerging from the left ventricle immediately divides into an ascending and de- scending trunk, one of which gives off both caro- tids and subclavians/ A—Right auricle of the heart. B—Left auricle of the heart. C—Pulmonary artery. D—Trunk of the aorta. E—Ascending aorta. F—Trunk of the right subclavian and carotid arteries. G—Left carotid. H—Left subclavian. I I—Descending aorta. Figure IV. Sometimes two common or anonymous trunks arise from the arch of the aorta, one of which gives off the carotid and subclavian arteries of the right side, the other the same vessels of the left side. This variety has been twice observed by Vinc Malacarne,® and once by BiuMi.fi I have seen it in the Anatomical Museum of Berlin. A—Aorta. B—Right common trunk. 3 •—Right subclavian artery. 2. —Right carotid artery. C—Left common trunk. 3. —Left carotid. 4. Left subclavian. D—Descending aorta. Figure V. There are very often only two trunks originat- ing from the arch of the aorta, the first and larger of which is composed of both carotid and right subclavian arteries, the second and smaller of the left subclavian. a, a, a, a.—Sternum of an adult cut in its middle part. b, b.—Sternal portions of the sterno-cleido mas- toid muscles. c, c.—Clavicular portions of the same muscles. d, d —Thyroid gland. e, —Trachea. f, —Right pleura. g, —Left pleura. A.—-Trunk of the pulmonary artery. i.—Right pulmonary artery. k. —Left pulmonary artery. l. —Trunk of the aorta. m. —Arteria innominata, which is sometimes ob- served longer. a Diss. de Circulo Sanguinis in Corde.

Taf. 6. f This distribution of tbe aorta occurs in animals of the order Pecora, in the sheep, goat, bull, stag, buck, reindeer, (Dauben - ton, 1. c. T. 12. p. 182 ;) both varieties of tbe camel, (Daulienton, T. 11. p. 260, p. 432 ;) chamois, (Dauberton. T. 12. p. 182 ;) also in the solidungula, the horse, ass, and zebra, (Daub. T. 12. p. 17 ;) in most of the belluae, v. gr. in the boar, the pecari, and rhinoceros, (Cuvier Anatomie Comparde, T. 4. p. 248.) It is rarely observed in the mammalia of the order Glires and Qua- drumana, yet I have seen it in the cavia agouti, and in the lemur mongoz. Daubenton has remarked it in the cavia cabybara (T. 12. p. 292.) and paea, (T. 10. p. 276,) in the lemur mongoz, (Tit. 13. p. 201,) and ring-tailed lemur, (ib. p. 189.) This disposition of the vessels seems to be peculiar to those mammalia provided with a long neck; and from it seems to have arisen the vulgar division of the human aorta into ascending and descending, which we find so often mentioned in the works of the older Anatomists. g Osservazione in Chirurgia, Torina, 1784, T, 2. p, 119. h Observationes Anatomieae, p. 133. I have remarked this distribution of the vessels in tbe bat; the left arteria anonyma was shorter than the right. Daubenton has observed it in the pteropus rufus, (T. 10. p, 70.) The other animals of the class Cheiroptera obviously have this arrange- ment of vessels. It is found also in the porpoise. (Cuvier. Anat. Compar. T. 4. p. 249.) It would appear that this distribution is chiefly to be met with in those of mammalia with short necks.
