infections ; but I think we may safely assume that, if the French 
troops were infected with Eimeria, they were infected with 
Isospora as well, especially as Isospora infections so far reported 
seem to outnumber the Eimeria infections. 
Porter, (13) in 1917, discovered two cases of infection with 
“Isospora bigemina var. hominis” in Johannesburg. One of 
these infections was in a Hottentot, and the other in a Dutch 
South African who had never been out of the country. No data 
are given that will aid in tracing these cases. Noc,(l2) mean- 
while, in 1916, had picked up a case of Isospora infection in a 
European at Saigon. The case Was lost to study after the first 
examination of the faeces, and Noc has ventured the supposi- 
tion that the man had been eating rabbits’ livers that were 
infected with Isospdra bigemina. As he gives no description 
of the cysts he found, it is impossible to pass judgment on this. 
No information was obtained as to the previous travels of 
the man. 
Noc, fortunately, was able to secure more detailed informa- 
tion concerning the travels of the man whose case he recently 
reported from Senegal. (12) His description leaves no room for 
doubt that the infection was with Isospora hominis. The man 
had been at St. Mihiel, and had been a prisoner of war in 
German camps in Westphalia, Wurtemburg, and Hanover, where 
the sanitary conditions were very bad. The patient had every 
opportunity to pick up his infection at any of these four places, 
and it seems to be perfectly reasonable to assume that the ulti- 
mate source of the infection was the eastern Mediterranean area. 
Snijders(i4) reported his case almost coincidentally with Noc, 
while Dobell (5) has confirmed his findings and has given the 
name Eimeria snijdersi to the parasite, thus bringing the total 
number of species of coccidia known to be parasitic in man up 
to five. 2 . 
Snijders’ case was presented by a man at Medan on the east 
coast of Sumatra, who had lived in the Tropics for ten years. 
He gave a history of amoebic dysentery extending back for five 
years. The infection seems to have been especially intractable, 
for it had failed to yield either to emetine or to emetine bismu- 
2 For the present, at least, I think we must accept Dobell’s judgment 
regarding Gubler’s coccidium of the human liver. Dobell has left the 
naming of this organism to some investigator who, in the future, may- 
run across and study it. He merely designates it as “an undetermined 
species of Eimeria (?) .”
