simple racemose kind, having an average size of ^ — Mt f and 

 are disposed around the sac to the number of from 2 to 5. 

 The smallest, of 0*1 — 0-16" , occur in pairs, attached to each 

 hair of the scalp; they are somewhat larger, 0*16 — - 24, in the 

 hairs of the beard, and the longer hairs of the chest and 

 axilla, in which situations several glands are usually disposed 

 around the hair follicle; the largest of all exist on the mons 

 veneris, the labia majora, and the scrotum, where, at all events 

 in the last-mentioned locality, they are found at the deepest 

 boundary of the corium, and the glands, from four to eight being 

 connected together, represent beautiful rosettes { — \ — 1'" broad. 



Attached to the sacs of the smaller 

 coarse hairs, I find smaller seba- 

 ceous glands of 006 — 0-24'", mostly 

 in pairs ; and also in the eyebrows, 

 eyelids, and the hairs at the en- 

 trance of the nostrils. The lanugi- 

 nous hairs have generally larger 

 glands, or aggregations of glands, 

 of \ — \'"; these are best displayed 

 in the nose, the ear (concha, fossa 

 scaphoidea), the penis (anterior 

 half), and the areola mamma, espe- 

 cially in the first of these situations, 

 where the glands often attain a 

 colossal size, and altogether pecu- 

 liar forms (fig. 85) ; the glands 

 generally have a diameter of \ — i'" 

 on the caruncula lachrymalis, the 

 lips, brow, thorax, and abdomen ; 

 they are somewhat smaller, i — f, 

 but almost always larger than 

 in the hairs of the scalp, in 

 the eyelids, cheeks, neck, back, and extremities. Of the 

 glands which are not connected with hair-sacs, only a portion 

 of those of the labia minora are of large size (0*14 — 0"5"') and 

 rosette-shaped, with aperture of 0'033'" ; the others are for the 

 most part simply tubular, and at most 0*12 — 0-16" lon^
