 which the vital fluid is implicated, viz., inflammation. In 

 the present chapter we treat of those diseases distinguished 

 as specific affections, originating in a faulty state of the 

 blood, and characterised by their specific efiects on the system 

 in general

Veterinary science has made great advancement in the

This disease is not very common in Canada ; only a few 

 cases have come under our notice. 



It is a generally received opinion that it depends on the
