COW-POX. 



This is the same disease appearing in the cow. There is 

 a preliininaiy slight fever, usually overlooked, succeeded by 

 some diminution and increased coagulability of the milk and 

 the appearance of the pox on the udder and teats. The ud- 

 der is hot and tender for a day or two, then little pale red 

 nodules, about as big as peas appear, growing to three- 

 fourths to one inch in breadth by the eighth or tenth day, 

 acquiring liquid contents, and often a central depression on 

 the summit. The liquid in each pock is contained in 

 several distinct sacs and cannot be all extracted without a 

 succession of punctures on different parts. It contains a 

 micrococcus. The liquid, at first clear, changes to yellowish 

 white (pus) and soon dries up, the whole forming a hard 

 cnist which is gradually detached. On the teats the blisters 

 are early ruptured and raw sores form, often proving very 

 obstinate, and even leading to inflammation of the udder, 

 abortion, or death. 



Treatment is scarcely ever demanded further than to ob- 

 viate sores on the teats. A mild laxative of Epsom salts is, 

 however, usually desirable. The teats may be smeared with 

 an ointment formed of an ounce each of spermaceti and al- 

 mond oil, and half a drachm of myrrh. Milking-tubes may 

 be necessary to avoid injury by drawing the teats. 



In many localities the disease appears in all newly calved 

 heifers on particular farms, in which case it would be well 

 to purify the barns by a thorough disinfection. 



SHEEP-POX. 



Though unknown in America there is no improbability 

 of this disease reaching us through importations of sheep, 

 hides, or wool. Like small-pox of man, it is only known as 

 a contagious disease. The incubation or latent period of
