C. A. Keefer, of Sterling, Ill., as experiment No. 8. One of 
these cows died of pleuro-pneumonia and the other has since been 
killed because affected with the same disease. 
Experiment No. 9 was made by John Boyd when he brought 
two cows from Clarke’s infected herd among his beautiful Jer¬ 
seys at Elmhurst. The record here is fourteen that have died or 
been killed showing symptoms and post-mortem appearances of 
contagious pleuro-pneumonia. Twenty-one cows in this herd 
were epxosed, twelve of which, or about 60 per cent., have al¬ 
ready contracted the disease; and this in addition to the two that 
were purchased, both of which were affected. 
Experiment No. 10 was Frisbie & Lake’s purchase of fifteen 
head from Clarke’s infected farm. These animals were pastured 
with the 250 which constitute their herd at Cynthiana, Ky. The 
results so far may be summed up as four dead and ten or twelve 
sick, with others coming down with the disease almost daily. 
Messrs. Frisbie & Lake did not believe in pleuro-pneumonia; 
they intended to protect their herd to the fullest extent of the 
law against the supposed sensational reports of interested veteri¬ 
narians, and they engaged one of the best lawyers in the State to 
defend them. Probably they accepted the view so industriously 
circulated in certain quarters that this is a disease of Jerseys and 
that their grades, at least, would certainly escape. Fortunately 
just as their case was prepared they decided to have a post-mortem 
examination made of a sick cow. The result was very well ex¬ 
pressed to me by Judge West, their counsel, when he said that 
the finest legal effort of his life was ruined by that examination. 
I have referred above to ten experiments with this disease, in¬ 
voluntary it is true, but experiments nevertheless, seven of 
which are on a larger scale than is proposed by the Live-Stock 
Exchange, and are just as conclusive as the experiment which 
they propose could be. More than six hundred animals, in all, 
have been exposed and ninety cases of pleuro-pneumonia have so 
far resulted, in spite of vigorous efforts to arrest the disease. A 
large number of these animals have been examined after death, 
and in every one of these has been found the characteristic ap¬ 
pearance of the lungs described the world over as peculiar to
