528 PROTOZOA 



rosettes with numerous segments, which are closely analogous to the 

 series seen in the asexual development (schizogony) of the malarial 

 parasites, but in addition there are certain coarsely reticulated forms 

 which may represent stages in sporogony or be due to degeneration of 

 the other forms." In our laboratory nine cases have been examined 

 with reference to the presence of these bodies, five autopsy cases and 

 four living, but so far only a few of the less characteristic forms have 

 been found, and these only in the five autopsy cases. 



Duval has just made the announcement that in fluid obtained through 

 blistering the skin of scarlet fever patients by a very quick method he 

 has obtained bodies which he interprets as forms of Mallory's protozoan. 



In our laboratory Field has obtained similar bodies by the same 

 method in both scarlet fever and measles cases, and in four cases of 

 scarlatiniform antitoxin rashes, more in the first two groups than in the 

 last. He has obtained them in no other cases so far examined. Nothing 

 positive can be said yet as to the nature of these bodies, though Field 

 has come to the conclusion that the majority of them are from degen- 

 erated leukocytes.
