It is the same disease as that which arises from the use of mowburnt hay. The horses urinate often; the urine is quite colorless, and it is discharged in immense quantities. The horse would drink for ever, and the water is hardly down his throat till it is thrown among his feet in the form of urine. In a day or two his coat stares, he refuses to feed, loses flesh, and becomes excessively weak. He may for a time continue at work; but if he catch cold, and remain at work while he has both the cold and the diabetes upon him, he often becomes glandered.

The horses may not all be alike. In a large stud some are always more affected by these bad oats than others. The worst must go out of work for a while, and some others must be spared as much as possible, while a few may continue at their usual employment. The oats must be changed. Give plenty of beans, some barley, and good hay. Let each horse have a lump of rock-salt, and a piece of chalk in his manger. Put some clay and bean-meal in the water. Carrots, whins, or grass, may be given with benefit. But by changing the oats, and diminishing the work, the disease will generally disappear. If all these means fail, medicine must be tried. A. veterinarian will furnish that of the proper kind. But nothing will arrest the disease permanently unless the oats be changed. If not very bad, they do for horses in easy work. But while a horse has diabetes, he can not maintain his condition for full work. He would lose flesh though he stood up to the knees in grain.

There is a kind of diabetes which does not proceed from bad food. It is accompanied with a good deal of fever, and requires different treatment; it may be suspected when the food has not been changed; but the eye is red, and the mouth hot, and the horse is dull for a day or two before the staling-evil is upon him.
