440 CATTLE. 



curry-comb, somewhat lightly applied. To this must follow the 

 application of an ointment Avhich appears to have a speci6c effect on 

 the mange, and which must be well rubbed in with a soft brush, or, 

 what is far better, with the hand, morning and night : there is no 

 danger of the disease being communicated to the person so employed. 

 The ointment must have sulphur as its basis, aided by turpentine, 

 which somewhat irritates the skin, and disposes it to be acted upon 

 by the sulphur ; and, to render it still more efficacious, a small por- 

 tion of mercury must be added. The following Avill be a safe and 

 very effectual application — there are few cases whicli will resist its 

 power. Take of flowers of sulphur a pound, common turpentine 

 four ounces, strong mercurial ointment two ounces, and linseed oil a 

 pint. Warm the oil and melt the turpentine in it ; when they begin 

 to get cool, add the sulphur, and stir the ingredients well together, 

 ahd afterwards incorporate the blue ointment with the mass by rub- 

 bing them together. 



Vast numbers of cattle have been lost by the use of stronger and 

 poisonous applications. Corrosive sublimate, in the form of an 

 almost saturated solution of it, is a favorite lotion with many prac- 

 titioners. Arsenic — hellebore — tobacco have had their advocates, 

 and have murdered thousands of cattle. 



The practitioner must not, however, confine himself to mere local 

 treatment; physic should always be administered. Sulphur, in 

 doses of eight ounces every third day, will matei-ially assist in effect- 

 ing a cure ; and on the intermediate days nothing better can be 

 given than the powder recommended for hide-bound (p. 439.) 

 Mashes also should be allowed every night. 



Mange, neglected or improperly treated, may degenerate into a 

 worse disease, but fortunately not one of frequent occurrence. The 

 scurf will be succeeded by scabs — there have been cases in which 

 the scabs have appeared from the beginning — and the skin becomes 

 thickened and corrugated, and covered with scales, and occasionally 

 the scales peel off, and corroding ulcers appear beneath. 



The same ointment, but with double the quantity of mercury, 

 must be used for this aggravated state of the disease, and a stronger 

 alterative powder, consisting of two drachms of Ethiop's mineral, 

 added to the one already recommended. All this mercury, however, 

 must be used with caution, for it is not a drug that always agrees 

 with cattle ; and salivation would, temporarily at least, and in most 

 cases permanently, injure the beast, both for the dairy and the 

 pasture. 



In those sadly aggravated cases that come under the observation 

 of the practitioner, in which the whole of the skin is thickened and 

 corrugated, with deep chaps running down on either side, or uniting 

 together in various directions — when within the substance of the 

 skin numerous tubercles can be felt, varying from the size of a millet-
