1889.] Arboreal Tadpoles. 385 
ing nests, which was already beginning to drop to pieces. In 
this were also a few tadpoles. A diligent search of the pool 
failed to reveal any tadpoles in its shallow, miry depths. The 
next day I revisited the spot. The nest I had designated 
for myself still remained undisturbed upon the branches, 
but was drenched with the passing showers. It rains at 
Nikko in July every day beginning about noon. I made a 
rough sketch of the object. The following day I repaired ta 
the spot to get the nest, and also armed with a large jar kindly 
provided by Dr. Whitney, into which to put the tadpoles, and 
scum should it come to pieces. Unfortunately during the 
night the elements had made partial wreck of the coveted 
prize. It was broken in places and hanging down in wet 
streamers. I took a number of these with the enclosed tad- 
poles and put them into the jar. But soon they dried up. All 
that I had left to me was a mass of partly desiccated scum,, 
with some dead tadpoles in it. I allowing this to dry out 
hard and in this state brought it home to America. 
Upon examination I find that the tadpoles have been pre- 
served in the mass in a highly desiccated condition. When 
alive they were about three quarters of an inch in length. In 
their dried form they are, it is needless to say, much smaller. 
By immersing in a mixture of glycerine and water, I have suc- 
ceeded in partially restoring the form to one or two of them. 
These with the bulk of the dried froth I have sent to 
Prof. Edw. D. Cope, of Philadelphia, who assures me that the 
phenomenon I have observed is one of much novelty.'
