This should be made as it is wanted, for, by keeping, the ingredients 
become hard, and are apt, when given in that state, to cause injury to 
the animal. 
By such slight and simple means, water farcy has generally been re- 
moved; but no delay should occur in having recourse to them, as some 
cases will set all endeavors at defiance, and delay is always dangerous 
where health is concerned. A few days of neglect will often permit the 
limb to become organized. It ceases to pit on pressure. Fibrin has

locked up for the night. The next day the animal is 
discovered breathing with difficulty, and having several parts of the body 
greatly enlarged. The creature appears, by the disorder, to be rendered 
stupid rather than insensible. It stands erect, but seems not to be 
acutely conscious of its condition. Not only are several portions of the 
horse’s frame swollen beyond all recognition, but through the skin there
