as an almost harmless substitute for a 

 very dangerous contagious disease. 



In cow-pox, after an incubative period 

 of from three to nine days, a slight fever 

 is noticed. This precedes by two or 

 three days the eruption, which is at first 

 a pimple, developing on its summit a 

 Vesicle, which changes to yellowish 

 lymph and a scab. This erupt'ion ap- 

 pears on the teats, udder, and flanks, and about the vulva, nose,' 

 mouth, and eyes. The pimples gradually increase in size, until 

 they are from one third to one inch in diameter. (See Fig. 965.) 

 The disease completes its course in from ten days to thr.ee 

 weeks. Very little if any treatment is required, other than good 

 nursing ; care must be exercised to prevent taking cold. The milk 

 should be withdrawn from the udder by means of the teat siphon, 

 illustrated in Fig. 962, to avoid the excessive pain caused by milk- 

 ing with the hands where there is a large number of inflamed vesi-r 

 cles on the teats. The sores on the teats should be anointed with 

 some simple ointment ; either belladonna or carbolic acid ointment 

 will be suitable. If the udder is highly inflamed, frequent bathing 

 with hot water, will be useful. Fomentations and poultices may be 

 used, and support by bandages, as shown in Fig. 966,'will be bene- 

 ficial.
