THE HORSE IN SICKNESS AND DISEASE 349 



White arsenic 5 grains. 



Powdered cantharides . . .6 grains. 



Sulphate of iron .... 2 drachms. 



Tartarised antimony .... 1 drachm. 



Mix with a handful of bran, and give in a feed of corn 

 every evening for a fortnight. Administer a dose of 

 "physic" after two-thirds of the medicine has been given, 

 and, as soon as it " sets," the remainder. 



Under VeT7}iifiiges will be found some formulae and 

 remarks. Mayhew gives a scale of doses of turpentine 

 adapted for the different ages of the horse : e.g., for a three 

 months' foal, half an ounce ; for a six months' foal, an 

 ounce ; one year old, an ounce and a half ; two years, two 

 ounces ; three years, three ounces ; four years and upwards, 

 four ounces. Take one pound of quassia chips, pour on 

 them three quarts of water, strain, beat up the turpentine 

 with yolks of eggs to make it blend with the infusion, add

 The licking of cold substances is a sign of disordered 

 stomach. The act of crib-biting is thus performed : The

 say the edge of the manger ; he violently extends his neck,
