HYDROPHOBIA IN BRITISH GUIANA.

meat subjected to ordinary cooking, Mr. Lewis found that 
no meat can be said to be “done” unless exposed to at least 
150° Fahr. As regards the amount of heat required to 
destroy life in cysticerci he adds :—After being subjected to 
a temperature of 130° Fahr. for five minutes, they may be 
considered to have perished. After exposure to this and 
higher temperatures, in no instance was he able to satisfy 
himself that the slightest movements took place in their sub¬ 
stance when examined under even a high power. After ex¬ 
posure for five minutes to a temperature of from 135° to 140° 
F., life in these parasites may be considered as absolutely ex¬ 
tinct. In no case was he able to detect a single live bladder- 
worm in portions of measly meat w r hich had been cooked in 
the usual way, and even in portions of it which had been 
rather under- than over-cooked. It may therefore be inferred 
that, with ordinary precautions on the part of the cook, the 
further development of cysticerci will be arrested. It is 
rarely that persons from preference partake of meat so much 
underdone as not to have been subjected in every part for 
five minutes to a temperature of from 135° to 140° F., after 
which exposure it may be confidently stated the entozoa will 
have succumbed.— Lancet. 
HYDROPHOBIA IN BRITISH GUIANA. 
Letter from Mr. W. F. B. Pollard. 
[To the Editor of the c Medical Times and Gazette . 5 ] 
Sir, —It may interest other subscribers to your journal be¬ 
sides myself to know that hydrophobia has appeared in a 
country supposed by its inhabitants to have been hitherto 
exempt from this scourge. From the statement, however, of 
Mosely that before 1783 it was not known in all the West 
India Islands, and from the remark of Larrey that it was un¬ 
known in Egypt, while Pruner found it there in 1847, it 
would perhaps be safer to infer that it has not visited this 
part of the South American continent for many years rather 
than accept the prevailing opinion that it is now seen here 
for the first time. It has undoubtedly been brought to this 
colony from Barbadoes. A few months ago some rabid dogs 
were observed in the country by a gentleman from that island, 
and the fact was made known in the newspapers. Unhappily, 
it was only read of by the majority to be ridiculed. 
The first case occurring here in the human being I was
