only to be removed by calomel and opium, which cause 

 their absorption. In this event take calomel, thirty grains; 

 opium, ten grains ; mix, and give once a day, for a week 

 or ten days. Good feeding will have to be given. 



Ringworm. — Porrigo, and Favus, are names given to 

 this disease. 



Symptoms. Small circular patches, or scales, sometimes 

 running together, forming large crusts and ulcers under 

 them, in which insects breed. This is a contagious disease, 

 and is communicated from man to animals, and animals to 

 man. The microscope has shown the presence of fungi in 

 the scab of ringworm, but whether it be merely the effect 

 of the disease, or otherwise, is not at present known. It 

 is, however, more likely to be the cause. 



TreatTnent. Wash and keep the parts clean, and aim at 

 iestroying the fungi. For this purpose remove the scab 

 as soon as formed, and apply a solution of oxalic acid to 

 the surface, using fifteen grains of the acid to an ounce of 

 water. Tar ointment, creosote, sulphur, and mercury, 

 have all been tried ; but none of these meet with so much 

 success as the solution of oxalic acid, just recommended.

Slobbering. — This is traceable in horses to a variety 

 of causes. We may enumerate large doses of aconite, or 

 veratrum; also, sore, or scald mouth, and in some cases 

 poisoning. Slobbering from eating second crop clover, 

 will be found treated of under the article Salivation, 

 (which see.) 



Slough. — The separation of a diseased or dead part 

 from the healthy portion. A slough may be of greater or-
