Sixth Biennial Report of the State Veterinarian of Michigan, 1895-96. By 
E. A. A. Grange, State Veterinarian, Lansing, Mich, 
The very full and lucid pamphlet bearing the above title 
comes to us with peculiar force, just at this time, for after scan¬ 
ning the 64 large and compact pages, teeming with the rarest 
and latest conclusions in modern sanitary medicine, only ob¬

age of progress and civilization the trading in politics has caused 
the displacement of this man to make room for one devoid of 
these valuable attributes. We know nothing of the personality 
of the new appointee, beyond the information that he is a non¬ 
graduate, and that is sufficient to know that however good a 
citizen he may be, he cannot be competent to succeed Prof. 
Grange. 
The body of the report is mainly filled by a very full consid¬ 
eration of the subject of tuberculosis in its various aspects, and 
is a valuable contribution to veterinary literature.

fected animals died in a few hours or at most in a few days of 
what veterinarians called “ catarrhe contagieux.” The animals 
secreted viscid mucous from the mucous membranes of the 
pharynx, eyes and nose, emaciated rapidly and died very quickly
