(c.) A trial of the rational interpretation of the immunity and of the 
particular réle of the tick. 
(d.) The manner in which bovine malaria exists in the Argentine Republic. 
(e.) The actual state of the prophylactic. 
(f.) The absolute inefficacy of quinine or arsenical compounds as a 
preventive or curative means. 
In all my researches I have been cordially assisted by the Argentine 
Breeders’ Commission, which, while continuing its own work, neglected 
nothing to facilitate my task; by the Minister for Agriculture, represented by 
his Director, M. Tidblom; and by a large number of breeders, friends of 
progress. 
Tam pleased to publicly tender my sincere thanks to all these devoted 
gentlemen. 1 must make special mention of M. Domingo Lahargou, who 
prepared the photographs here given, and whose artistic and disinterested 
science triumphed over all difficulties. 1 trust he will accept my gratitude. 
I must not forget my young assistant, M. Marcel Lignitres, with whom I 
have shared fatigue, disappointment, and success. He has for this reason a 
right to a share in the results obtained. 
Lastly, my thanks are due to the printer, Penser, for the minute care he 
has bestowed upon this work.
