RUPTURE OF THE DIAPHRAGM. 
The animals had only been perceived to be unwell from 
twelve to twenty-six hours before their death. 
On examining the two calves that were still living, we 
found one griped, the other not. The pulse was quick and 
feeble; the mucous membranes injected; the eyes sunk in 
their orbits ; the mouth and tongue clammy, and the nose 
dry. In both, diarrhoea was present, and in one it was at¬ 
tended with tenesmus: these animals also died. 
The yearling bull, of which mention is made in the inclosed 
reward bill, presented all the symptoms described above, 
and he likewise died. 
We brought away some of the viscera and a quantity of 
the contents of the stomachs and intestines of those animals 
which we had examined, and the following are the results of 
our investigation. The stomachs with their contents having 
been boiled in distilled water, and the fluid filtered, to it was 
added,— First , a solution of nitrate of silver, to which had 
been added a little ammonia: this threw down a lemon- 
coloured precipitate— the arsenite of silver. Second, a solution 
of the ammonio-sulphate of copper, prepared in a similar 
way as the above: this threw down a grass-green precipi¬ 
tate—arsenite of copper. 
Thirdly , some of the fluid was put into a fit vessel with 
some lumps of zinc and dilute sulphuric acid. The disen¬ 
gaged gases being burnt, on holding over the flame a piece 
of glass a minute quantity of metallic arsenic was deposited 
upon it. We also used lime water, which precipitated the 
arsenite of lime; likewise a solution of bichromate of potassa ; 
but these tests are not certain, the former throwing down a 
precipitate from a solution of oxalic acid, and the latter from 
a solution of tartarized antimony. 
CASE OF RUPTURE OF THE DIAPHRAGM. 
By R. Hawes, M.R.C.V.S., London. 
The morbid parts, consisting of the heart and a portion of 
the diaphragm, which accompany the following description, 
were taken this afternoon (February 5th, 1859) from the 
bodv of an aged roan gelding, of the light cart-horse breed, 
about 15£ hands high. The only history I can give of the 
case is, that at a quarter before eight this morning a message 
reached me, requesting my immediate attendance at the 
stable. I was, however, unable to start on the instant, being
