After the animal is on the road to recovery, stop the use of these medicines and give a tonic consisting of nitrate of potash or saltpeter and ground gentian root, half and half. Give a teaspoonful three times a day. While the animal is sick, a little boiled flaxseed mixed with a soft food will keep the bowels regular. It is not wise to give purgatives, hence it is wise to give an injection consisting of warm soapy water, so as to empty the bowels. From two to four weeks of rest and care should be allowed for complete recovery. =INFLUENZA.=--A specific disease of the horse affecting the mucous membrane of the air passages. When the mucous membrane of the eyelids is affected, pink eye results. Sometimes the mucous membrane of the intestines is affected, in which case colic or inflammation of the bowels results. The common cause is exposure to cold. If no work be required, plenty of fresh air be supplied, no drafts admitted and careful nursing otherwise, the disease will run its course in from two to three weeks and no medicines will be necessary. In cases where considerable cough prevails, the custom of putting a piece of camphor about the size of an egg in a pail of boiling water and holding the horse’s head over it from a quarter to a half hour at a time is to be commended. The bowels should be kept free and open. Any of the ordinary purgatives will do. If weakness occurs, give 4 tablespoonfuls each of tincture of ginger, ground gentian root and sweet spirits of niter in a half pint of water three times a day. Two tablespoonfuls of nitrate of potassium given once or twice each day in the drinking water is also desirable. As the trouble abates, the medicines suggested before may be dropped and in their place a teaspoonful of sulphate of iron and a tablespoonful of ground gentian root may be given daily in a bran mash or oatmeal gruel. =INTESTINAL WORMS IN HORSES.=--Intestinal worms may be classed as large and small. The large worms inhabit the small intestines, and the small ones the large intestines, the larger class of worms being more readily reached by worm destroyers than are the smaller ones, as the small intestines begin at the stomach and as remedies leave the stomach, the worm soon receives the dose prepared for it, while if one dose has to pass through about 60 feet of intestines before reaching the smaller worms in the larger intestines, much of the worm remedy is lost by mingling with the food, and diluted by mixing with the digestive fluids. Thus what is a remedy for the large species of worms will have little effect upon the smaller ones.
