Figs. 100 and 101. — Showing the effects of inanition upon the testis in the young albino 

 rat. X514. Figure 100 shows a cress section of a seminiferous tubule in a normal albinojrat 

 (Si 6.0) 3 weeks old. Figure 101 is a similar section in a rat (S. 7.32) held at constant body 

 weight by underfeeding from 3 to 1 o weeks of age. A, B,C, Allen's cell types of spermatogonia ; 

 D. C, degenerated cytoplasm; D.P.S., degenerating primary spermatocyte; L, lumen; M.F., 

 mitotic figure; M.P., membrana propria; Mu.C, multinucleated cell; P.S., primary sperma- 

 tocyte; 5, spermatogonia; S.C., Sertoli cell. (Siperstein '21.)

Figs. 102 and 103. — Showing the effects of inanition upon the adult testis in the albino 

 rat. X514. Figure 102 shows a portion of a seminiferous tubule in cross section from a 

 normal rat (St 5.2) 8 weeks old (practically adult structure). Figure 103 shows the corre- 

 sponding structure in an adult rat (S. 25) after 9 days inanition on water only, with 35 per 

 cent loss in body weight. M.G.C., multinucleated giant cells; M.P., membrana propria; P.S., 

 primary spermatocytes; S, spermatogonia; S.C., Sertoli cell; Sp., spermatozoa; Spt., sper- 

 matid; S.S., secondary spermatocytes. (Siperstein '21.) 



Figure 100 shows the normal seminiferous tubule in the albino rat at 3 

 weeks of age, and Fig. 101 the changes in a rat held at constant body weight 

 by underfeeding from 3 to 10 weeks of age. Figure 102 shows the structure of
