ON THE “ GILA MONSTER.” 9 
arm, a little higher than before. As in the first experi- 
ment there was no room to doubt the penetration of the 
teeth. The cat again licked the wounds and for a consid- 
erable time was occupied in dressing them. There was no 
disposition to go to sleep as on the day before. In two 
hours, as soonas the cat was inclined to pay no farther 
attention to its wounds, it was killed and the skin removed 
the better to note the effects of the bites. The fore-arm 
and hand were found to be swollen to twice the size of the 
opposite hand and arm. ‘The track of each tooth was 
marked by the blood in and close around it, and the num- 
ber and depth left no doubt of the conclusiveness of the 
experiment ; the teeth had gone to the bones and between 
them. I saw nothing by which to distinguish the cuts from 
those made by a needle. ‘There were no signs of disor- 
ganization in either the first or the second bites. Nothing 
could be seen in the way of discoloration or otherwise to 
give reason for any other conclusion than that the kitten 
- would have entirely recovered in a few hours, by the time 
the swelling had gone down, if it had been allowed to live. 
The outcome of such observations as have been made 
on this specimen has been confirmation of the opinion that 
the species is venomous to a certain degree, to an extent 
that, while it may most often prove fatal to very small an- 
imals, is only in exceptional instances deadly or perhaps 
even dangerous to larger ones. The effect on the kitten 
was identical with that on the puppies in Sumichrast’s ex- 
periments. That poison was introduced by the bite was 
evident from the distress and swelling occasioned. 
Dr. Fischer has described and figured secretory apparatus 
on the lower jaws ; no glands have been found onthe upper. 
There is an important question to be solved in connection 
with this apparent lack of venom-secreting organs on one 
of the jaws, which is quite as well prepared for its use as
