Resume .—These cases, of which eighty per cent, have done 
well, ten per cent, an improvement and ten per cent, badly, 
have extended over a period of nearly eight years. It should 
be borne in mind that the changeable nature of horseflesh in 
regard to barter, should always be considered in giving sta¬ 
tistics in the results of operations, and a surgeon’s success may 
be limited to his knowledge as to the history of the case, as 
long as he can keep track of it. I would state that especially 
in the last three years, in nearly every instance the case 
has been followed up as closely as possible, which has been 
much more easily done here, where horseflesh does not change 
hands so often as it does in the East. There has been within 
the last two years twenty-five animals that I have lost track of, 
as they were shipped either to the Kansas City, St. Louis or 
Buffalo markets. These I have not entered in the list. 
ASTHMA AND PULMONARY EMPHYSEMA. 
By R. B. Plageman, D.V.S. 
The word asthma is commonly used as synonymous with 
dyspnoea, or difficult breathing. Here is at once a great 
practical difference from the dyspnoea of pleurisy, of pneu¬ 
monia, of the diseases of the heart. The dyspnoea of pulmo¬ 
nary emphysema is made with a double expiratory movement, 
and not accompanied with any wheeze. 
Seeing how violently all the muscles of inspiration and ex¬ 
piration partake in the struggle of a severe paroxysm in 
heaves, we cannot but wonder much at the notions of the 
older writers, that the disease depended on an excessive and 
convulsive action of all these muscles.
