albuminous, such as wheat-bran or middUngs, pease, beans, and milk. 

 Indeed, an exclusive milk diet is one of the very best remedial agencies. 

 It may be given as skim milk or butter-milk, and in the last case com- 

 bines an anti diabetic remedy in the lactic acid. Under such an exclu- 

 sive diet recent and mild cases are often entirely restored, though at the 

 expense of an attack of rheumatism. Codeine, one of the alkaloids of 

 of opium, is strongly recommended by Dr. Tyson. The dose for the 

 horse would be three grains thrice daily. In cases in which there is 

 manifest irritation of the brain bromide of potassium, four drams, or 

 ergot, one-half ounce, may be resorted to. Bitter tonics (especially nux 

 vomica, one-half dram) are useful in improving digestion and general 

 health. 



Excessive Secretion of Urine, or Diabetes Insipidus. This 

 disease is also known as diuresis or polyuria. It consists in an excessive 

 secretion of a clear, watery urine of a low specific gravity (1.007) with 

 a correspondingly ardent thirst, a rapidly advancing emaciation, and 

 great loss of strength and spirit. 



Causes. It may be caused by any agent, medicinal, alimentary, or 

 poisonous, which unduly stimulates the kidneys; the reckless adminis- 

 tration of diuretics, which form such a common constituent of quack 

 horse-powders; acrid diuretic plants in grass or hay; new oats still im- 

 perfectly cured; an excess of roots or other very watery food; a full 

 allowance of salt to animals that have become inordinately fond of it; 

 but, above all, feeding on hay, grain, or bran which has not been prop- 

 erly dried and has become musty and permeated by fungi. Thus hay, 

 straw, or oats secured in wet seasons and heating in the stack is espec- 

 ially injurious. Hence this malady, like (sleepy staggers), is wide- 

 spread in wet seasons, and especially in rainy districts. 



Symptoms. The horse drinks deep at every opportunity and passes 

 urine on every occasion when stopped, the discharge being pale, watery, 

 of a low density, and inodorous; in short, it contains a great excess of 

 water and a deficiency of the solid excretions. So great is the quantity 

 passed, however, that the small amount of solids in any given specimen 

 amounts in twenty-four hours to far more than the normal, a fact in 

 keeping with the rapid wasting of the tissues and extreme emaciation. 

 The flanks become tucked up, the fat disappears, the bones and muscles 

 stand out prominently, the skin becomes tense and hidebound, and the 

 hair erect, scurfy, and deficient in luster. The eye becomes dull and 

 sunken, the spirits are depressed, the animal is weak and sluggish,
