PLEUROPNEUMONIA. 39 
performed by him with the ecraseur. I am sorry to say I was 
not fortunate enough to see him operate on that occasion. 
I have at different times, during my course of study at the 
College, through the kindness of Mr. William South, witnessed 
many highly interesting operations at their infirmary in New 
Bond Street, and though invited to be present at that particular 
occasion was unavoidably prevented at the last moment. Hence, 
no doubt, the mistake. I may add that I learned from my fellow- 
students of the highly satisfactory character of the operation to 
which Mr. South refers. 
I am able to bear out the remarks of Mr. South respecting 
the mode of using the ecraseur, as both my partner, Captain 
Bussell, and I, besides removing tumours, warts, &c., have cas¬ 
trated horses, bulls, sheep, dogs, and cats, with this instrument 
with the greatest success, excepting sheep over six months old, 
and for my part I do not recommend the use of the ecraseur in 
the castration of the last named animals. 
The instrument we use is “ Farmer Miles's ” pattern, which 
we have found equal to every operation up to the present, where 
such was required. The chains belonging to these I have no 
doubt are stronger than the one used by Mr. South, which, I 
presume, was made for use in human practice. 
I would, by the way, suggest that intending purchasers should 
apply to Mr. Miles’s authorised agents, Messrs. Krohne and Sese- 
man, as I have heard from the “ Farmer ” that there are other 
productions called his wanting in two essentials. 
Pathological Contributions, 
PLEURO-PNEUMONIA. 
The information received from the Netherlands is very 
encouraging, as during the four weeks ending 29th of 
November only one case of this disease is reported as having 
occurred in that country. 
From the United States we hear that pleuro-pneumonia 
is decreasing in Pennsylvania, and that no cases have been 
reported from the States of Illinois, Iowa, Michigan, 
Indiana, or Wisconsin. The subject of diseases of animals 
appears to be receiving a considerable amount of attention 
in that country, and. it is stated that every state proposes 
to petition Congress to pass a stringent National Cattle 
Disease Law. 
The introduction of neat cattle into the United States 
from Canada is now prohibited.
