184 ON INOCULATION AS A MEANS FOR THE 



plienomeua only of such wounds, when containing some slightly 

 irritating agent. 



" 4. That with a high temperature, roughly made incisions, 

 and serous fliiid a few days old, local ulceration and gangrene, 

 producing occasionally the death of the patient, will follow 

 inoculation. 



" 5. That sero-purulcnt matter, taken from an inoculated sore, 

 causes more speedy action than the scrum obtained from a 

 diseased lung, and that removes cannot be effected on scientific 

 principles. 



" 6. That oxen are not only susceptible to the action of a 

 second, but of rej^eatccl inoculations with the serous exudations of 

 a diseased lung. 



" 7. That an animal inoculated with the serous exudation is 

 in no vjcuj protected even from the repeated action of the sero- 

 purulent fluid which is produced in the wound as a result of the 

 o]3eration. 



" 8. That animals not naturally the subjects of pleuro- 

 pneumonia, such as donkeys, dogs, &c., are susceptible to the 

 local action, both of the serous exudation from the lung, and the 

 sero-purulent matter obtained from the inoculated wounds. 



" 9. That the serous fluid exuded from the lungs is not a 

 specific ' virus,' or ' lymph,' as it is sometimes designated. 



" 10. That inoculations made with medicinal irritating agents 

 will be followed V)y similar phenomena to those observed in 

 inoculations with the exuded serum. 



" 11. That inoculation often acts as a simple issue, and that 

 the security which at times the operation apparently affords 

 depends in part upon this, but principally on the unknown 

 causes which regulate the outbreak, spread, and cessation, of 

 epidemic diseases. 



" 12. That inoculation of cattle, as advocated and practised 

 by Dr Willems and otliers, is not founded on any known basis 

 of science or ascertained law, with regard to the propagation of 

 those diseases commonly called specific. 



" 13. That pleuro-pneumonia occurs at various periods of 

 time, after a so-called successful inoculation. 



" 14, And lastly, that the severity of pleuro-pneumonia is in 

 no way mitigated by previous inoculation, the disease proving 

 equally rapid in its progress and fatal in its consequences in an 

 inoculated as in an ir?iinoculated animal.

The ju'actice of inoculation has been conducted some years 

 by Mr Priestman, M.E.C.V.S., Caledonian Eoad, London, and 

 at one time, about ten years ago, we were frequently informed 

 of the wojider-working of the same, but subsequently the
