against the contagion. If the disease is typhoid fever, we should 
expect to find that contaminated water is a principal medium 
through which the disease germs pass from one animal to another. 
How far exemption from attack may he secured, when the food 
and drink are free from all possible contamination, has not, so 
far as I know, been determined. Second.—It seems, also, to be 
established that healthy hogs, if subjected to hard driving for 
considerable distances in hot weather, or if crowded together in 
large numbers, may develop the disease de novo; and, possibly, 
other conditions and circumstances not yet understood, may tend 
to a similar result. 
Treatment .—With this malady it is especially true that pre¬ 
vention is better than cure; the attempt to medicate a case of 
Hog Cholera, when, by so doing, there might be danger of ex¬ 
posing other animals, is the reverse of economy. When it is 
certain that an animal has this disease, it should be killed imme¬ 
diately and buried, and the whole premises thoroughly disinfec¬ 
ted. For this purpose, all litter and rubbish should be burned, 
and the pens, or styes, fumigated with burning sulphur. Hogs 
that have been in contact with sick ones, may be expected to 
show symptoms of the disease, after thirteen or fourteen days, at 
furthest, if the weather be cold; if the weather should be very hot, 
the period of incubation may be shortened to three or four days. 
During the period of incubation, sulphur should daily be given 
with the food, or the hyposulphite of soda may be u§ed instead. 
This is a cheap drug, and a sufficient quantity will be taken, with¬ 
out objection, if dissolved in the drink. Some farmers think they 
have kept off the disease, after exposure, by acidulating all the 
food slightly with sulphuric acid; others believe that the sulphate 
of iron is equally effectual. The carbolic, cresylic, and salycilic 
acids may prove better disinfectants than those already named; 
or, possibly, change of quarters may be more benefical than any 
plan of medication. If an attack of the disease cannot be pre¬ 
vented, and loss of appetite, with nausea and constipation, are 
noticed, then laxatives are clearly indicated, and sulphur enough 
to act may easily be given with the food or drink; or castor oil, 
with spirits of turpentine, may be administered to an animal that
