B. INTERNAL FEATURES. In dissecting the rabbit, it is 

 best to lay it upon a flat board somewhat longer than the 

 animal. In examining the head, it is best to remove the 

 skin entirely. To do this, cut through the skin around the 

 neck and pull it off over the head wrong side out, cutting 

 carefully where needed. 



Head. Note the cartilages at the bases of the ears, that 

 support them, and also the muscles that move the ears. 

 Cut off the ears and note the auditory canal that leads 

 into the head. 



After the skin is removed begin at the corner of the mouth 

 and cut through the cheek in a posterior direction, severing 

 the lower jaw from the upper where it is hinged, and then 

 forcibly turn that half, or ramus, of the lower jaw, break- 

 ing its connection in front. This will lay open the mouth 

 cavity. 



Observe that there are two pairs of long curved teeth 

 in front, the incisors, one pair on each jaw. How do they 

 come together? Turn back the cut half of the lower jaw 

 and observe this point. Are the edges sharp or dull ? 

 Note the pair of small incisors on the upper jaw just back 

 of the large ones. What are the incisors for? 



Note farther back, the molars. How many pairs above 

 and below ? How do these meet ? Are the surfaces smooth 

 and are they flat or chisel-edged ? Note the space without 

 teeth between the incisors and molars. What teeth occupy 

 this space in your own mouth ? 



Note the tongue. What shape is it? Where is it fas-
