INOCULATION WITH OVINK ViUUS. 3a 



recorded, and by the result, that great nicety is required 

 as well in the selection of the fluid for ovination as 

 in the manner of performing the operation ; two points 

 on which the educated veterinary surgeon alone is 

 capable of forming a correct judgment. 



It will be seen that, early in the above cases, there 

 existed a considerable amount of inflammatory action, 

 accompanied with a discharge of pus from the inocu- 

 lated places ; and that both the sheep suffered severely 

 througliout the progress of the malady, and ultimately 

 died from the fever of small-pox, which, during the 

 continuance of the papular stage of that disease, is so 

 often attended with a fatal result in the human subject. 

 The fever, however, took on a more aggravated cha- 

 racter in the sheep into whose system the pus was 

 introduced ; a circumstance we were not surprised at, 

 knowing that the absorption of this fluid, even when 

 there is no reason to doubt its purity, is frequently 

 attended with serious consequences. 



We shall hereafter describe the means to be adopted 

 to obtain the ovine lymph, and also the time when it 

 is most to be depended on for inoculation : we there- 

 fore close this Chapter by remarking, that to secure 

 success, and indeed safety, in the operation, lymph of 

 a pure quality should be chosen, and deep punctures 

 avoided in introducing it into the system.
