78 REPORT ON DOURJNB. 



red blood corpuscles and blood plasma ; the blood of a donkey 

 fretus, about 5th month, also contained the pyroplasma. So that 

 the parasite is capable of passing from the maternal to the festal 

 circulation, through the walls of the placental vessels. 



It would appear that man and animals alike all present the 

 same species of pyroplasma, but modifications in the specific 

 characters of the haematozoon probably are developed during the 

 passage through the different animals. In February 19 03, one 

 gwalla, a pahari, suffered at Bareilly, during the prevalence of 

 Texas Fever in cattle, from benign Tertian, associated with a 

 pyroplasmosis, during which serious symptoms of a remittent type 

 of fever were present together with intermittent attacks of hsemo- 

 globinuria, lasting for three weeks in all. During tbe present cold 

 season, the blood of one Veterinary Assistant Janki Nath, a native 

 Laboratory bearer, and my own, have exhibited the same forms of 

 pyroplasmata. Slight accessions of fever very seldom exceeding a 

 maximum of 37'6C. (99'8F.), hemicrania, sweating after the 

 slightest exertion, but with complete absence of hsematuria or 

 harnoglobinuria, were the symptoms always associated with the 

 presence of the pyroplasma in the blood of man. It is well known 

 that cattle and dogs contract the disease from the bites of ticks, and 

 it is more than likely that equines and ovines and probably camels 

 become infected by the same species of parasites. But man is not 

 troubled with ticks except under exceptional circumstances, and 

 therefore it is necessary that some other carrier be found. One has 

 not very far to look for at the time of the year when this form of 

 disease is most rife. Anopheles have not yet developed and only 

 the Culex fatigans is to be observed. A full account o the life- 

 history of the organisms found and their connection with the 

 Ixodes, Culicidse, and the Diptera generally, together with the 

 symptoms produced in the host, will be published separately.
