HITCHCOCK'S ANATOMY 



crosses the os innominatum lying just beneath the skin. Here 

 an efficient compression may be made, since all the anterior 

 part of the thigh and the whole of the leg proper, is supplied 

 with blood from this artery.

 age, directly over the wound, thoroughly wet with cold water, 

 will check hemorrhage sufficiently, until a surgeon can be 

 called.

In all mammals the heart is 

 divided into four cavities, as 

 in man. Its form, however, is 

 more rounded and less elon- 

 gated. In one species of the 

 whale this organ is cleft in a 

 peculiar manner, the division 

 between the two ventricles 

 being indicated externally by 

 a deep fissure in its apex. In 

 the Ox, Hog, Sheep, and 

 Goat there are always found 

 one or two bones in the di- 

 visions between the ventri- 

 cles. In most mammals it 

 is placed more in a right line 

 with the middle of the body, 

 and not so obliquely as in 

 man.

 the heart of the W r hale, the Ox, the Sheep, and Goat? Where is the heart located ic
