THE INTEGUMENT. 427 



IV. THE ORGAN OF TASTE. ORGANON GUSTUS. 



The sense of taste is located in the mouth-cavity, especially 

 in the mucosa of the tongue and the soft palate. The proper 

 organs of taste are the so-called taste-buds, found on the 

 papillai of the tongue, the soft palate, etc. Their exact distri- 

 bution in the cat has apparently not been worked out. 



V. THE INTEGUMENT. INTEGUMENTUM COMMUNE. 



The skin of the cat consists of the usual two layers, the 

 outer epidermis and the inner fibrous corium. The skin is 

 particularly thick and tough about the sides of the neck and 

 face. 



The skin is covered almost completely with fine soft hairs. 

 Only the end of the nose, the pads on the soles of the feet, 

 and the nipples are without hair. A number of long stiff sen- 

 sory hairs (vibrissas) are found on the upper lip, the cheek, and 

 above the upper eyelid. 



The pads on the soles of the feet are cushion-like projec- 

 tions of skin, composed largely of connective and elastic tissue 

 and fat. There is one large pad for each foot, and in addition 

 a small pad for each digit. The fore limb has besides a small 

 conical pad which is situated almost exactly over the pisiform 

 bone. 



The nails are horny outgrowths of the epidermis, covering 

 the distal phalanges. 



The muscles of the skin are the cutaneus maximus and 

 platysma; these have been described (page 93). The super- 

 ficial facial muscles are differentiations of the skin-muscles.
