Inoculation for Pleuro-P neumonia in Cattle. 



383 



visited Hasselt, and made inquiries independent oi Dr. Wil- 

 lems, and found there were many objectors to the practice, 

 and also doubters of its efficacy. I learned also from him 

 that in the neighbourhood of Brussels very few cattle had been 

 inoculated, and that several veterinary surgeons in different parts 

 of the country, from observing the ill effects, had declined to go 

 on with the practice. 



As an addendum to this report I trust I may be permitted to 

 direct the attention of the Royal Agricultural Society of England 

 to a series of questions attached hereto, which have been pre- 

 pared on the subject of pleuro-pneumonia by a committee of 

 a Society established in the metropolis for investigating the 

 cause and nature of epidemic diseases. As a member of that 

 committee I can bear testimony to the value of these questions ; 

 and as the first object is to circulate them as extensively as pos- 

 sible among the cattle proprietors and others in this country, T 

 trust this will be received as an apology for my intruding them 

 on your notice. If we can but obtain a sufficiency of answers 

 from all parts of the country to most of these questions, I have 

 no doubt that we shall be enabled to publish such a report as 

 must prove of the greatest value to the whole community, and to 

 the agriculturist in particular. 



1. Has the disease termed pleuro-pneumonia existed either among 

 your own cattle, or among any which are under your immediate 

 observation ? 



2. Has it prevailed in your neighbourhood, and if so, how near your 

 own premises ? 



3. Did the disease Jirst appear among the " old stock" of the farm, 

 or among the animals which had been recently purchased ? 



4. Has it attacked any other variety of animals besides oxen ? 



5. What is the usual health of the animals kept on the fanu, their 

 average age and condition ? 



6. Were the breeding or the fatting stock first affected ? 



7. Can its appearance in your locality be traced to any special or 

 direct cause, such as the introduction of diseased animals ? 



8. To what do you attribute its outbreak in your own herd ? 



9. Have the cows, either in calf or in milk, beeu more susceptible to 

 the disease than the oxen ? 



10. Have you any proofs of calves being affected at birth or venj 

 shortly afterwards ? 



11. What was the state of the weather at the time of the outbreak, 

 and were the animals, when attacked, exposed to, or protected from its 

 influence ?
