LESSON I. 



DISSECTION OF A RABBIT AND OF A DOG. 



IN the following, the descriptions in large type apply more particularly 

 to the rabbit, but the general directions for dissection serve also 

 for the dog : some points in which the two animals differ, and 

 some which are better seen in the dog, are printed in small type. 



A. 1. Make a median incision through the skin, down 

 the whole length of the front of the body from 

 the neck to the pubis, and reflect the skin as far 

 as possible on both sides. 



In dissecting a female rabbit note, just under- 

 neath the skin, the thin arborescent mammary 

 glands, one to each mamma. 



2. Observe the thin, pale, abdominal muscles. 



It is better to dissect out the individual mus- 

 cles in the dog as below, but the dissection 

 may be done on the rabbit. 



In the dog observe 



a. The tendinous aponeuroses of the abdominal 



muscles forming in the middle line the Unfit 



alba.
