460 SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 
myself on his right, since the needle can be most readily 
introduced here. The vein being well raised, I make a 
small button-shaped opening through the skin with the 
point of a straight bistoury. This prevents the effort 
which would be otherwise required in piercing the vessel. 
I then, having thus exposed the vein, take a trocar, No. 
3 or 4, and plunge it by a single thrust into the vessel and 
from below upwards. As soon as the needle has penetrated 
the vein, the escape of blood through the canula will in¬ 
dicate the trueness of its course. I then rapidly remove 
the cord from the vein and adjust the injecting tube to the 
mouth of the canula. Then the assistant, at my word of 
command, forces in the dose, measured by the degrees marked 
on the instrument; this I vary according to the age and 
strength of the animal and the severity of the attack. Thus, 
I use the following doses : 
Grammes. Iodine.

Feser, of Munich, has attempted to resolve the question 
of the transmissibility of charbon to fish. It has been sup¬ 
posed by some that cold-blooded animals cannot convey the 
contagium of this disorder nor afford a nidus for growth 
and multiplication of Bacillus anthracis. We have recently 
been informed of a case in which fish died in large numbers, 
and where they were thrown up on the banks of the river 
the cattle became affected with anthrax (Mr. T. C. Toop, 
M.R.C.V.S., in a paper on “Anthrax”); Jessen states that 
in 1826, during the excessively warm summer, while char¬ 
bon raged among horses, many fishes with malignant ulcers 
were taken in the River Wolcho. Forel, Duplessis, and 
Ogle affirm that a disease resembling charbon, in 1867-68 
destroyed a large number of the fishes in Lake Leman, but 
that disease, although associated with Bacteria in the blood, 
was not transmissible to other fish. Corti describes an out¬ 
break which was observed in the Po, notably among eels. 
But, in spile of the mortality which these epizootics have 
occasioned, we are not warranted in positively considering 
them anthracoid. Oemler’s inoculations show that carp
