212 DISEASES OF ANIMALS. 



physic. The probang is a leather tule, one and a hill 

 inches in diameter ; it may be made stiff enough to enter 

 the stomach by inserting in it a rod or stick. At the 

 insertion end of the probang, there should be a leaden 

 tube, with holes in it. The distance from the teeth to 

 the stomach of a large ox is six feet. 



When cattle have suffered a severe attack, the stom- 

 ach will be weak for some time, and they should be fed 

 lightly, and have a good dose of herb drink daily, for 

 several days. 



ULCERS. 



When ulcers break out, physic, but do not bleed. Fo 

 ment with warm water, and wash in soap suds ; and 

 apply equal parts of turpentine, hartshorn, and campho- 

 rated spirits. Wash the ulcers several times a day in a 

 solution of chloride of lime. Give mashes and thick 

 gruel. A poultice made of the soft pulp of roasted car- 

 rots is excellent for old sores and ulcers.

MILK SICKNESS. 



This name, together with "Trembles," has been 

 applied to a peculiar and most malignant disease, occur- 

 ring in some sections of the Western Slates, affecting 

 horses, cattle, sheep and goats, and persons who use the 

 meat or dairy products of infected cattle. It prevails 

 more or less in all the Western Stales, and extends as far 

 south as Mississippi. It is most common in Indiana and 

 Illinois ; never occurs east of the Alleghany Mountains. 

 Among early settlers it made dreadful ravages, and often 

 caused the breaking up of communities, and seeking 

 more favorable locations. 



Animals may be so much diseased that their flesh and 

 milk will affect persons partaking of it, and yet the ani- 

 mals themselves exhibit no evident symptoms of disor- 

 der. The latent disease may be discovered by subjecting 

 the animals to violent exercise, that will bring on tre- 

 mors, spasms, convulsions, or death, according to the 

 amount of disease; in this way bulchrrs try suspected 

 animals.
