528 THE URARI, Oil ARROW- POISON OF THE INDIANS. 
As to the typhus, it is neither more nor less to be feared 
now in England than it was one, or two, or six years ago ; 
since there are few years in which it does not prevail in 
Poland, or in some part or other of Russia in the neighbour- 
hood of the Baltic, so as to be at any moment prevalent in 
parts far enough removed from the provinces of Southern 
Russia, from whence English commerce obtains so many 
hides and so much tallow. Now England has not for a long 
period adopted sanitary measures against animal productions 
of Russia; and yet those productions have not imported the 
bovine plague amongst the English cattle. M. Renault is 
convinced that the English administration, when better 
informed, will soon rescind the rather precipitate measures 
it has recently adopted. 
Finally, he adds that this measure is so much the less con- 
siderate as it is now proved that tanned leather, hides dried 
in the air, and melted tallow, the produce of animals infected 
with typhus, have never imported the disease. 
We regret being unable to give more than an analysis, 
necessarily incomplete and distorted, of the clear and elegant 
extempore address, which during an hour captivated the 
attention of the assembly. 
M. Yvart has completed the communication of M. Renault, 
by adding some new details, and by a spirited critique on an 
official note of the English Government, in which they have 
given the premonitory symptoms of the disease, which are 
nothing more than an inexplicable melange of the symptoms 
of three or four very different disorders.”

M.M. Cl. Bernard and Pelouze, on opening the animals 
poisoned by the curare, with which they experimented, found 
the blood always black, difficult to coagulate, and no longer 
<f rutilant,” by coming in contact with the air. 
These observations, as far as it regards the state of the 
blood of animals killed by the curare, are entirely opposed to
