vomica to the amm. curb, pill, and after the inflammation has 
passed support the strength with gruel, to which alcohol must be 
added, but never give alcohol while inflammation of a mucus 
membrane exists, or the disease will be aggravated. In the rheu¬ 
matoid form, use hot packs to which tr. opii has been added, and 
cover with oiled silk, if possible; internally give carbonate of 
potash or soda, using hypodermic injections of morphia solution 
till the acute sjunptoms are passed. The same instructions and 
treatment given in the first form, will be carried out in connec¬ 
tion with the treatment of the other forms of this disease. 
The next disease most common to the railroad horse is colic, 
either spasmodic or flatulent; the former most prevalent. 
The treatment I found most applicable and witli best results, 
is hydrate of chloral in pill form, adding pulv. zingiberis 3 b to 
chloral § i, and a few drops of water to triturate into proper con¬ 
sistence, using oiled paper for a cover; one dose being gener¬ 
ally sufficient in spasmodic colic, but if not relieved in one hour, 
[ prefer to give morphia solution by hypodermic injection, 
though a second dose of chloral can be driven at that time with 
safety. The dose of physic that is so often resorted to for such 
cases in private practice is seldom, if ever needed for these 
horses. In the flatulent colic, the chloral does little or no good, 
but rely on puncturing with the trocar; first cutting the hair 
off a circumscribed portion and covering with a plaster of bella¬ 
donna after the operation. 1 never had any complications arise 
or bad results follow it. Internally I give terebinthinse, 3 ii in 
an egg emulsion, preferring it to oil, which is so nauseous to the 
horse ; besides, it serves every purpose of protecting the mucus 
membrane from the irritant action of that drug. I also see the 
rectum is emptied, and give the above with glycerine as an 
enema. In addition to the above, the hypodermic injection of 
morphia solution will allay the pain and stimulate the heart. 
The next most common disease of the railroad horse is 1am- 
initis, and its pathology as well as its etiology is very imperfectly 
understood. Suffice it to say, the coronary band, the lamina, its 
corium or basement membrane and the velvety tissue, as well as 
the bone, (or pedis) may all be involved. These soft tissues con-
