PLATE LIII. 



Fig. 1. A sebaceous gland from the caruncula lachrymalis in 

 the human subject ; the follicles, on closer exami- 

 nation, I find to be provided with minute hairs, 

 similar to those which are present in the sheep and 

 some other animals. 



Fig. 2. An entire Meibomian gland. 



Fig. 3. Sebaceous glands in connection with a hair of the 

 scalp. These glands are easily procured still at- 

 tached to the hair follicle, provided the portion of 

 integument from which they are to be obtained be 

 permitted to undergo a slight degree of decom- 

 position. 



Fig. 4. Illustrations of mucous glands. The centre figure 

 represents a portion of a gland and several of the 

 apertures by which the follicles in the larger mu- 

 cous glands communicate with each other.
