SMITHEIELD CATTLE SHOW. 
precaution had been taken, apparently in good time, to save 
their lives. All these animals being subjected to dissection, 
there could not be found the slightest corrosion, or even 
inflammation of any consequence; only the gall-bladder of 
the dog was found considerably distended, and in some of 
the ducks various serous membranes, that of the liver espe¬ 
cially, had assumed a whitish and granulous appearance. As 
to the nature of the poison, if there could have been any 
doubt about it, it would have been at once dispelled by the 
characteristic green band peculiar to thallium in the spectral 
analysis of the organs of the dead animals. Eight days later 
the other hen was taken ill. Its wings hung down, it could 
hardly walk, and when it wanted to peck its food, its neck 
seemed to have lost the power of bending down sufficiently, 
so that its beak did not reach the food. The hen was killed, 
and thallium found in the intestines, but in a very small dose 
indeed, and the other organs did not contain any. M. Lamy 
next administered a decigramme (a grain and a half) of the 
sulphate to a dog two months old, and it died forty hours 
after taking it. Hence M. Lamy justly infers that sulphate 
of thallium is a powerful poison, producing pain in the intes¬ 
tines and paralysis of the lower members. This poison and 
the nitrate have but little taste, and might therefore be used 
for criminal purposes; but fortunately there is not a poison 
that can be traced with more certainty through spectral 
analysis than this. The new method of analysis bids fair to 
render excellent service in cases relating to forensic medi¬ 
cine.
