of animals which had died of the malady, being received at the 
College. The communications which accompanied these speci- 
mens showed that not only cattle, but sheep, pigs, and even horses, 
had died suddenly, even when believed to be in perfect health, 
from this remarkable affection. Science has still much to do in 
investigating the causes of this disease. The facts appertaining 
to many of the outbreaks are irreconcilable with each other. 
Animals are struck down with the disease on farms where 
the malady was never known to have occurred before, and then the 
disease ceases as suddenly as it had appeared. These things often 
take place in localities far distant from each other, and where the 
greatest possible differences exist in the prevailing breed of cattle, 
character of soil, system of farming, management of animals, 
&c. Not unfrequently, however, coincidences occur which 
would almost admit of being regarded as consequences. Thus, 
the feeding of cattle on fields recently manured with liquid 
manure or town sewage, or where the water supply is contami- 
nated with the drainage of houses or filthy farm premises, is 
accompanied with an outbreak of splenic apoplexy. In many 
of these cases, everything short of removing the animals for a 
time to another farm, even if merely a contiguous one, fails to 
arrest the progress of the malady. 
An outbreak of splenic apoplexy is also not unfrequently asso- 
ciated with the use of compound feeding-cakes, cotton-cake, and 
other allied substances, especially when any of these are given in 
excess. It may be asserted that many feeding-stuffs of this kind 
are most valuable when used to a limited extent, but positively 
poisonous if this limit be exceeded, as is often the case in the 
attempts which are made to push on the condition of animals 
too rapidly. 
Besides the morbid specimens thus specially alluded to, 
mention may be made of the receipt of others which point 
to an increase of a peculiar parasitic disease, known commonly 
as " measles," of the pig. This name of the disease is very 
inappropriate, as leading to the most erroneous conclusions with 
regard to the nature of the malady. " Measly pork " has an 
appearance of the flesh being studded with small watery cysts. 
These cysts are living entozoa, known ordinarily as hydatids — 
the hydatis cellulosas. This condition of the flesh would be more 
properly described as misty or mizzly, and no doubt " measle," in 
this instance, is a corruption of the old English word " mizzle." 
The term " mizzly-pork " expresses the condition of the flesh 
of a pig, the subject of the malady, better than any other. 
Hydatids are only immature tape-worms, and when such pork is 
eaten by man, tape-worms will abound in his intestines. 
Several prosecutions of low-class pork-butchers have recently
