(2) Coccidioides immitis and Cocc. pyogenes, Rixf. et Gilchr. R. Wernicke 

 describes round bodies, with shells 0*003 0*030 mm. in diameter, discovered 

 by his pupil, A. Posada, to the number of ten, in the giant cells of granular 

 proliferations situated in the corium. The patient, a native Brazilian soldier, 

 exhibited a great many uneven protuberances on the skin of the face 

 which were diagnosed as mycosis fungoides. In the case of an apparently 

 identical cutaneous disorder in a man, aged 40, whose disease had already 

 persisted for eight or nine years, Rixford and Gilchrist performed the 

 autopsy and found similar bodies not only in the nodules, but in the 

 lungs, liver, kidneys, genitals and lymphatic glands. They measured 

 O'Oi6 0*030 mm. in diameter, and in their developed state were sur- 

 rounded by a capsule with double outline, and had granular protoplasmatic 

 contents, but exhibited no nucleus. The coccidial nature of these foreign 

 bodies appears somewhat more probable from the fact that the author 

 states that he saw as many as 100 merozoites in each schizont. In a second 

 case, of a man, aged 33, the disease started with an eruption on the forehead ; 

 soon nodules appeared in the skin, and after only two months the lymphatic 

 glands were affected. The patient died three months after the commence- 

 ment of the disease. On examination, coccidia-like bodies, 0.020 0*035 mm. 

 in diameter, some of which were in the act of schizogony, were also found 

 in the nodules. The authors consider that the parasites of the one case 

 differ specifically from those of the other case, and therefore give them 

 different names ; whether, however, they related to coccidia or sporozoa, it 

 may be surmised that in all three cases only ONE species came under observa- 

 tion. (Wernicke, R., Uber einen Protozoenbefund bei Myc. fung. [C. f. B. u. P.,
