gj. to gij. ; sheep, 3j. to 3ij ; pigs, Jss. to 3j ; dogs, grs. 

 v. to grs. xx. Soap, resin, with other diuretics, and free 

 solution in water, hasten and increase the action of nitre on 

 the kidneys. 



A diuretic mass is thus made : Take soap and nitre, of 

 each Ibs. ij. ; resin, Ibs. iij. ; Venice turpentine, Ibs. ij. ; oil 

 of turpentine, fviij. Melt the soap and resin over a slow 

 fire ; remove the mixture from the heat, and when it has 

 somewhat cooled stir in the other constituents. The dose 

 of this mass is ij. The balls are made up with a little 

 linseed meal or flour. 



As an alterative and febrifuge nitre is given in about half 

 the doses used to cause diuresis, is repeated several times 

 a day, and is generally conjoined with other medicines. A 

 febrifuge and laxative ball for the horse is prepared with an 

 ounce of nitre, a drachm of aloes, and twenty grains of 

 calomel. For a horse with catarrh and impaired appetite, 

 a useful draught is made with Epsom salt two ounces, and 

 nitre and ammonia acetate solution, of each an ounce, 

 dissolved in gruel or ale. Catarrhal symptoms and sore- 

 throat are relieved by four drachms nitre and one drachm 

 each of ipecacuanha, camphor, and belladonna extract, 

 made into bolus, and repeated every four or six hours. An 

 ounce each of potassium nitrate and carbonate, with two 

 drachms iodide, are useful in rheumatism. For cattle 

 similar combinations are serviceable. For them a con- 

 venient alterative is made with two ounces each of nitre, 

 sulphur, and ginger, given in treacle and water, or in ale. 



For the dog a good febrifuge consists of five grains each 

 of nitre and Dover's powder, and one grain calomel, placed 

 upon the tongue, or bolted in a piece of meat, or made into 

 a pill. Cats take about half the dose requisite for dogs.

Chlorine gas is passed rapidly into a strong solution of 

 potassium carbonate and calcium hydrate. The hypo- 

 chlorite first formed is decomposed by the heat evolved.
