pressant in nervous excitement, lockjaw, mad staggers, etc. Dose ot 

 the tincture, 1 ounce. 



Linseed. — Valuable as a diet. Nos. 5, 6. 



Linseed OII.~^ose, as a cathartic, 1 to 2 pints. A bland and 

 unirritating purge, useful in young and weakly animals. Often valuable 

 in choking in cattle. Externally it is a soothing dressing. Nos. 89, 91. 



Magnesia, Sulphate of {Fpsom salts, Svlphateof mag- 

 nesia).— Do&e, as a purgative in cattle, 1 to 2 pounds ; calves, sheep and 

 pigs, 3 to 6 ounces. A popular febrifuge, purgative and alterative, but 

 not desirable as a purge for horses, as it sometimes acts very violently 

 on them. It is, however, valuable to them in small doses, repeated, say 

 1 to 2 ounces, several times a day, to ''cool the blood," in influenza, 

 pneumonia, and, indeed, most febrile inflammatory disorders. It should 

 be given in ten or fifteen times the quantity of water, and mixing it 

 with molasses and ginger will nearly conceal the taste, and allow of 

 giving it in soft food. Nos. 144, 145, 331, 332. 



Mercurials. — Mercury or quicksilver is used as Mercurial oint- 

 ment , Mercurial liniment, Mercury with chalk {Gray Powder), Red 

 Precipitate {Red Oxide of Mercury), Calomel {Mild Chloride of mer- 

 cury), Corrosive sublimate {Corrosive Chloride of mercury) and Citrine 

 ointment {ointmerit of Nitrate of Mercury).— Of these we may use in- 

 ternally, mercury with chalk, dose 15 to 20 grains, in indigestion and 

 diarrhea in young calves ; but calomel, dose 30 to 60 grains, is gen- 

 erally preferred, combined with chalk, magnesia or opium. Calomel is 

 much less used now than formerly, and is mostly confined to some 

 diseases of the stomach and bowels. Corrosive sublimate is a very 

 valuable internal remedy in arresting the slimy, bloody discharges of 

 chronic dysentery in cattle. Dose, horses and cattle, 5 to 8 grains ; 

 sheep and pigs, 1 grain. Externally mercurial ointment is used as a 

 stimulant for old sores, ulcers and swellings, and for destroying lice and 

 vermin. But for the latter purpose other agents are better, as the mer- 

 cury is apt to be absorbed, and to poison the animal. A weak solution 

 of corrosive sublimate, 20 grains to the pint of water, is used for the 

 same purpose. Citrine ointment is used in chronic skin diseases, ring- 

 worm, etc., but is easily absorbed, and must be cautiously used. Nos. 

 76, 90, 147, 162, 186, 194, 234, 236, 239, 350, 383. 



Muriatic Acid {EydrocUoric acid, Spirit ofsalt).—Tfose of 

 the diluted medicinal acid 1 to 2 drachms, in a quart of water. An ex- 

 cellent remedy, given with the food, in indigestion in lambs and calves
