Introduction. 
In no part of India, perhaps, are ampler opportunities available for 
the study of tropical diseases than in the Presidency of Madras. This 
will be borne out by the fact that quite recently the interesting discovery 
was made in the Madras Veterinary College Hospital of the existence 
in these parts of two distinct parasites, causing the protozoal biliary 
fever among horses. I propose in the course of this article to chronicle 
the details of my observations with regard to this discovery, feeling 
sure that they will be read by all Veterinarians with interest, though 
they may probably arouse a feeling of melancholy among lovers of 
horse flesh. There is no disguising the fact, that through lack of 
facilities for prosecuting the study of tropical diseases in Madras the 
Veterinary Profession has been greatly handicapped. It is therefore 
with no little satisfaction that we hail the announcement made by 
Sir Harold Stuart, member of the Executive Council of the Government, 
at a recent public function in Madras, that at no distant date there 
would be a fully equipped School of Tropical Medicine in the City. 
Nuttall and Strickland (1912) have shown that two distinct parasites 
and consequently two distinct diseases occur in horses suffering from 
“biliary fever” and have named the particular infections, which I am 
now dealing with, after the parasites which produce them, i.e. Piroplas- 
mosis due to Piroplasma or Babesia caballi Nuttall (1910) and 
Nuttalliosis due to Nuttallia. equi Laveran (1901), Franca (1909). 
Dschunkowsky and Luhs (1913) moreover have since reported that 
horses and mules in Transcaucasia may become infected either with 
Nuttallia, equi or Piroplasma caballi.
