ARE FURTHER EXPERIMENTS NECESSARY ?

raised, viz., is this disease contagious pleuro-pneumonia. In this 
connection I would respectfully invite your attention to the follow¬ 
ing facts: 
At the first post-mortem examination which I made in this 
State, at Elmhurst, I invited Mr. J. H. Sanders, member of the 
late Treasury Cattle Commission, who enjoys the respect and 
confidence of the great body of cattle-owners of the country, and 
who is familiar with the appearance of the lungs of cattle affected 
with contagious pleuro-pneumonia. At the second autopsy were 
present Dr. N. H. Paaren, State Veterinarian, and Dr. J. H» 
Pauch, secretary of the State Board of Health, gentlemen emi~ 
nently qualified for deciding as to the nature of the disease. At 
my third examination, which occurred in a herd in the State of 
Ohio to which was traced the outbreak in this State, was present 
Captain Win. S. Foster, President of the Ohio State Board of 
Agriculture. Seven animals were killed at that time, every one 
of which showed the unmistakable signs of pleuro-pneumonia. 
At various examinations made by Dr. Paaren in the State of 
Illinois have been present Prof. Smith, principal of the Toronto 
Veterinary College, Dr. Holcombe, State Veterinarian of Kansas, 
and other veterinarians of standing. These gentlemen have with¬ 
out an exception expressed a decided opinion that the disease is 
contagious pleuro-pneumonia. Dr. Haggard, of Kentucky, an 
English veterinarian who had heretofore expressed himself to me 
as skeptical of the existence of contagious pleuro-pneumonia in 
the United States, was called a few days ago to decide as to the 
nature of the disease introduced into the herd of Frisbie & Lake, 
of Cynthiana, Ky., by the cattle from Clarke’s herd, of Geneva, 
Ill. After slaughtering a diseased animal and making a thorough 
examination he unhesitatingly pronounced the disease identical 
with the contagious pleuro-pneumonia that he had been familiar 
with in England thirty years ago. It is a fact, therefore, that the 
disease in question has been seen by a considerable number of 
good authorities and that none of these have expressed a doubt 
of its being pleuro-pneumonia. 
In addition to this the owners of most of the affected herds 
have seen the post-mortem examinations of their animals and can
