OF THE GLANDS OF THE SKIN.

0-024-0-035 of a line in breadth ; the latter have two to three, or at most 

 five, terminal vesicles, and measure 0-080-18 of aline altogether. The 

 apertures of both kinds of glands, 

 \vhich have a diameter of 0-02-0-06 

 of a line, are easily seen. With re- 

 gard to the position of the glands, 

 I would remark that I have never 

 failed in finding them, 10-50 and 

 more, in number, on the inner la- 

 mella of the prepuce, especially in 

 the neighborhood of the frcenulum, 

 and its anterior part ; while on the 

 glans itself and its neck, they are 

 sometimes totally absent, sometimes 

 they occur on its anterior surface, 

 and then generally in great numbers 



(up to 100). On the prepuce, the glands are for the most part racemose, 

 in the penis more simple. Their contents exactly resemble those of the 

 sebaceous glands, viz. cells containing fat, of which more will be said 

 below. 



The sebaceous glands of the external sexual organs in the female, are 

 found, generally in great numbers, on the inner and outer surface of the 

 labia minor a, and some of them are as large as those belonging to the 

 fine hairs on the labia majora, while some are smaller. I have never 

 found sebaceous glands in the glans and inner -lamella of the prceputium 

 clitoridis, although Burkhardt speaks of such in the corona clitoridis, 

 but, in a few instances, I have met with them about the urethra and the 

 entrance of the vagina. Resembling the sebaceous glands in all essential 

 points, except their larger size, are the Meibomian glands in the eyelids, 

 of which a more particular description will be given when we treat of 

 the eye. 



According to E. H. Weber (Froriep, "Notiz.," Marz, 1849), the 

 smegma prceputii of the Beaver, the " Castor" is not, in the main, a 

 glandular secretion, since only a small portion of the pouch in which it 

 is secreted is furnished with very simple, rounded, lenticular glandules, 

 the largest measuring ^d of a line. The secretion, in individuals of 

 both sexes, may rather be described as a laminated substance lining the 

 entire " castor pouch," and consisting merely of epidermic cells and 

 minute fatty globules. Leydig ("Zeitsch. f. w. Zool.," Bd. II., pp. 22, 

 31, et seq.), finds no glands at all in the " castor-pouch ;" and according 



FIG. 86. Two sebaceous glands; the larger, 1, from the inner lamella of the prepuce; 

 the smaller, 2, from the glans penis: a, glandular epithelium continued into the stratum 

 Malpighii of the skin; 6, c, contents of the gland, with scattered larger fat drops; g, horny 

 layer of the epidermis, projecting somewhat into the duct. Magnified 50 diameters.
