and for other purposes.” These three acts constitute the entire 
object of the existence of the Bureau of Animal Industry ; they 
define its work, viz. : Extirpation of contagious diseases at 
home. Prevention of importation of contagious diseases from 
foreign lands. Inspection of meat for home consumption and 
of that exported to foreign countries. 
It is unnecessary to state that these three fundamental laws 
were amended at various times, as the occasion required. Among 
these amendments, which had the effect of rendering the work 
more thorough and efficient, I may mention that of 1895 relating

the traffic in Southern cattle (to prevent the spread of Texas 
fever). 
(2) The pathological department, which is principally en¬

order to determine their nature, causes, and treatment, together 
with the most practical method of prevention. 
(3) The biochemical department,' to which are assigned the 
chemical problems .arising during the investigation of disease, 
and the preparation of tuberculine, malleine, and the various 
serums for the prevention and cure of diseases. 
(4) The zoological laboratory, to which is assigned, the study
