INOCULATION FOR PLEURO-PNEUMONIA IN CATTLE. 451 
however, we must leave the opinions and the recommendations 
of the Committee, and pass on to show what conclusions 
have been come to by other continental investigators. 
In our first Report it will be seen that allusion is made to 
certain causes which induced the Government of Prussia to 
delay its official inquiry into the subject. Subsequently, 
however, it commissioned Dr. S. Ulrich, Veterinary Professor 
of the Royal Academy at Moglin, to proceed to Hasselt, and 
to report the result of his investigations. We are unable to 
give the full particulars of the experiments had recourse to by 
M. Ulrich on his return, or the conclusions to which he 
arrived, but that he reported upon the whole in favour of in- 
oculation may be gathered from the following letter sent to 
the Earl of Clarendon by Mr. J. R. Curtis’ Her Majesty’s 
Consul at Cologne.* 
“British Consulate, Cologne; March 11, 1853. 
“ My Lord, — Since I had the honour last year of bringing under the 
attention of Her Majesty’s Government the great importanpe of the 
recent discovery made by Dr. Willems, of inoculating cattle as a pre- 
servative against the Pleuro-pneumonia, or commonly known in England 
under the name of the “new disease,” by the virulence of which thou- 
sands of cattle are carried off annually, and against which all medical aid 
has up to this period proved insufficient to check its infectious ravages, I 
have not lost sight of this important question, and the various improve- 
ments which longer experience has introduced into this new system; and 
I consider that I should be failing, in my duty if I did not call your 
Lordship’s attention to a report which has been forwarded to me upon 
this subject by Dr. Sticker, Royal Veterinary Surgeon for the district 
of Cologne, a translation of which I now beg leave most respectfully to 
enclose. 
“ As a Committee has been appointed in London for the investigation 
of this most important question, by the Royal Veterinary College, I 
think your lordship will find that the valuable information afforded by 
Dr. Sticker’s report is calculated to throw additional light upon the subject 
which will be brought under the consideration of the said Committee, 
and may consequently be of great assistance in solving the question at 
issue, and thus render considerable benefit to the agricultural interest of 
Great Britain. 
“ I further beg leave to inform your lordship that Dr. Sticker has at 
the same time invented a new instrument for effecting the inoculations 
according to his system, and has expressed a desire that a specimen of 
the same should respectfully be presented to His Royal Highness Prince 
Albert, who takes so lively an interest in the solution of the important 
question to which Dr. Sticker has devoted his constant attention ; and I 
beg leave to forward the same to your lordship under a separate cover, 
respectfully leaving it for your lordship ta decide whether with propriety 
it can be presented to His Royal Highness. 
“In conclusion, I may be allowed to state that this question has 
attracted the serious attention of the Prussian Government, these pro- 
* Papers respecting Pleuro-pneumonia in Cattle, presented to the House 
of Lords.
