EXTENSION OF THE CATTLE PLAGUE. 
Our object in thus alluding to the mixture of other beetles, 
accidental or otherwise, with the true blistering one, is not 
only to put the members of the profession on their guard 
so that they may not be deceived, but also to direct their 
attention to the following communication received from Mr. 
B. Cartledge, M.R.C.V.S., Sheffield. 
My Dear Sir. —Since you first sent me for trial, some of 
the Mylabris Cichorii, which is now four years ago, I have 
ceased to employ Cantharides as a blister. 
In my opinion there is no comparison between the two 
vesicants, and an extensive and varied practice has, I think, 
given me a fair opportunity of forming a judgment in the 
matter. 
The advantages possessed by the Mylabris over the Can- 
tharis are as follow :— 
1. The action of the former is quicker and more decided. 
2. The vesicles produced are more numerous. 
3. They cause less pain. 
4. The swelling of the parts sooner subsides. 
5. Cantharides are inadmissible in certain diseases, on 
account of the absorption of their active principle by the 
kidneys : not so the Mylabris. 
6. The Mylabris are cheaper than Cantharides. 
The Oleum Mylabris, I make as follows :— 
Mylab. Cichor. in fine powder .... 1 part, 
Ol. Olivae.26 parts. 
Digest in a water bath for three hours, then filter for use. 
I never use any other form of blister than this; but, if 
desired, an JJnguentum Mylabris might of course be made. 
I however find that the oil is more easily applied, particularly 
in cold weather, and where dependence has to be placed on a 
groom for its proper application, which is frequently the case, 
this is not to be lost sight of. 
I am, yours, &c. 
To Professor Morton. 
EXTENSION OE THE CATTLE PLAGUE. 
Recent accounts from Galicia, state that the Rinderpest 
is again raging to a fearful extent in many parts of that 
country, causing the destruction of hundreds of Cattle. Its 
extension towards the Prussian frontier from Austro-Poland, 
is creating great anxiety, and the authorities have ordered, 
among other things, that all cattle coming from the Austrian 
dominionsshall be subjected to a quarantine oftwenty-one days.
