MEDICINES USED IN THE TREATMENT OF CATTLE, 468 



Lead, Sugar of — (Superacetate of Lead.) — This, mixed with 

 the suhacetate of copper (verdigris, which see,) forms a useful oaustic 

 for the destruction of fungous growths. 



Goulard's Extract. — (Liquor Plumbi Superacetatis.) — When 

 the skin is unbroken, this preparation of lead is completely thrown 

 away, whether used either as a lotion to subdue inflammation, or to 

 disperse tumors or effusions. It is principally serviceable, applied 

 in a very dilute form, to abate inflammation of the eye. 



White Lead (Subcarboxas Plumbi) is the basis of a cooling, 

 drying ointment, used chiefly for excoriations, or superficial wounds. 



Lime. Carbonate of Lime, Chalk, — This is a useful ingredient 

 in all the drinks given in diarrhoea or dysentery. In every stage of 

 these diseases there is a tendency in the fourth stomach, and perhaps 

 in the intestines, to generate a considerable quantity of acid, than 

 which a greater source of irritation can scarcely be imagined. The 

 chalk, or the alkali of the chalk, will unite with this acid, and neu- 

 tralize it, and render it harmless. In the diarrhoea of the calf it is 

 absolutely indispensable, for there the acid principle is frequently 

 developed to a great degree. The dose will vary from a drachm to 

 an ounce. 



Chloride of Lime. — The list of medicines for cattle does not con- 

 tain anything more valuable than this. As a disinfectant — if the 

 walls, the floor, and the furniture of the cow-house or stable, are 

 twice or thrice well washed with it, the sound cattle may return to 

 the building with perfect safety, however contagious may have been 

 the disease of those that had previously perished there. Applied to 

 the pudenda of the cow that has aborted, it destroys that peculiar 

 smell which causes abortion in others, more readily than any prepara- 

 tion of the most powerful or nauseous ingredient. In blain, garget, 

 foul in the foot, and sloughing ulcers of every description, it removes 

 the fetor ; and, if the process of decomposition has not proceeded 

 too far, gives a healthy surface to the ulcers which nothing else 

 could bring about — and, administered internally in blain, in the ma- 

 lignant epidemic, and in diarrhoea and dysentery, it is of essential 

 service. In the last disease it is particularly beneficial in changing 

 the nature of the intestinal discharge, and depriving it of its putridity 

 vmd infection, and disposing 'he surface of the intestine to take on a 

 more healthy character. Half an ounce of the powder, dissolved in 

 a gallon of water, will give a solution of sufficient strength, both as 

 a disinfectant applied to the cow-house, and for external and internal 

 use as it regaids the animal. 



Linseed. — Nothing can compare with the linseed meal as an 

 emollient poultice — if the ulcer is foul, a little of the chloride of 

 hme should be mixed with it. If the object of the poultice is to 

 bring an ulcer into a proper state of suppuration, a little common 

 turpentine may be added ; but the cruelly -torturing caustics of the
