THE OX AND THE DAIRY. 257 



frequent and violent rubbings. Occasionally the surface of 

 the skin becomes covered with scabs, which peel off, and are 

 succeeded by foul ulcers. In the mean time the animal is 

 infested with lice ; they abound in myriads, tormenting the 

 miserable creature, and combine with the disease of the skin 

 to render it an object of disgust and apprehension. Not only 

 are these parasites communicated to healthy cattle in the 

 same field, but the disease of the skin also ; the slightest 

 contact, or the circumstance of lying on the same spot, is 

 sufficient to cause the communication either of the mange or 

 of the lice, or of both. 



Cattle infected with the mange should be kept strictly 

 apart from all others ; the first thing to be done is to render 

 the skin as free from scurf, loose hairs, and dirt, as possible ; 

 this may be done by means of a wisp of straw, or the curry- 

 comb : then let a strong sulphur ointment be well rubbed in 

 with a hard brush. 



The following ointment generally succeeds : 



Flowers of sulphur, one pound ; turpentine, four ounces ; 

 strong mercurial ointment, two ounces ; and Hnseed oil, a 

 pint. Warm the oil, and mix the turpentine and sulphur 

 with it, incorporating the whole well together; afterwards 

 add the mercurial ointment, by rubbing the whole together 

 in a large mortar, or by means of a stout spatula on a slab. 



This ointment must be carefully applied to every part, and 

 will soon begin to take effect. In the mean time, it will be 

 well to give internally six or eight ounces of sulphur, with a 

 drachm or even two of sethiops mineral, every third day. 



Some persons employ tobacco-water, as a lotion in this 

 disease, but this is a dangerous remedy ; it cai$es trembling, 

 sweating, utter prostration of strength, and sometimes even 

 death. Others use a strong solution of corrosive sublimate, 

 a still more dangerous application, and one which has caused 

 the death of cattle in numerous instances. We have alluded 

 to its effects when noticing poison. If this deadly poison is 

 deemed requisite in very inveterate cases (and it is better in 

 these cases to effect a gradual than a rapid cure), the follow- 

 ing prescription is recommended :
