MATERIA MEDICA AND THERAPEUTICS. 49 



alkalies, it converts albumen into peptones, emulsifies and saponi- 

 fies fats. Best administered about three hours after feeding, as 

 the acid of the stomach destroys its action. Dogs take from 

 4 to 10 grains. Foals and calves from 15 to 60 grains (with 

 Bicarbonate of soda). 



INGLUVIN. — Is prepared from the gizzard of the domestic 

 fowl, and owes its digestive action to its bitter principle; it is 

 used in vomiting of pregnancy. For women 10 to 30 grains, 

 and in proportionate doses for dogs. 



PAPAIN-PAPAYOTIN— This is obtained from the Papaw 

 or Carica papaya tree of the tropics. As- it is taken from the tree it 

 is too powerful a digestive to be given internally, but a prepara- 

 tion of it is called Papoid or Papain. It is soluble in water, and 

 is given in 1 to 5 gr. doses for the human. Foals and calves 

 would take 5 to 30 grs., and dogs 1 to 5 grains. It can also be 

 given to horses. It acts equally well whether in presence of an 

 acid or alkali, and its action is continued into the intestines. It 

 digests all kinds of food, and is undoubtedly the best of the arti- 

 ficial digestive ferments for our animals. 



A 5 to 10 per cent solution, or about J / 2 to 1 dr. to the 1 oz. of 

 water is used to dissolve diphtheritic false membranes. It is 

 also introduced into tumors and cancers for the purpose of di- 

 gesting them. Sometimes it is used in fistulous withers in the 

 above strength. It is known as vegetable pepsin. It converts 

 albuminoids into peptones, starch into maltose ; and emulsifies 

 fats. 



ACIDUM LACTICUM, Lactic Acid — Properties. — A 

 syrupy liquid containing 75 per cent of absolute lactic acid, pale 

 wine color, and mixes in all proportions in water, alcohol and 

 ether. 



Antagonists and Incompatibles. — Alkalies and mineral salts. 



Synergist. — Pepsin, vegetable acids, hydrochloric acid, etc. 



The dose for colts is 3j — 3ij.; calves 3j — iij.; for dogs 10 — 

 60 Ms., Horses gss-gj (well diluted). 



Physiological Action. — Aids digestion, promotes appetite. 

 Large doses cause pain and flatulence ; when lactic acid is in ex- 

 cess in the blood it is supposed to cause rheumatism ; if admin- 

 istered during diabetes will cause rheumatism.
