sanguineus, but the investigations of Dr. J. Braxton Hicks 
has shown that many of the forms which have been classed 
under this and other heads, and some of which are green 
whilst others are red, are the motile conditions (called gonzdia) 
of Lichens. I have shown that some of the green-colored 
forms, commonly ranked as animals under the name of Hu- | 
glena, are the motile forms of alge, and the red coating so 
common in this locality, and which I have found from early 
spring to late in the fall covering many hundred square feet 
of the surface of fresh water, is evidently a state of an alga 
also. This subject is one of great interest, and calls for 
further patient study. For some time I have been collecting 
observations thereon, and hope before long to lay them be- 
fore the Lyceum. We come now to the showers of “ honey.” 
These are no showers at all, but merely the juice of plants 
caused to exude in consequence of the puncture of insects— 
“plant hoppers” so called—as I had excellent opportunity 
of proving, as this substance was very common in the fields 
upon the stalks of grass, around Hanover, N. H., last summer. 
Pror. EGuLeston said that he had recently seen some 
Chinese Jade, and asked the question whether any one really 
knew what Jade was. The specimens he saw had recently 
been brought from China, and were different from the Chal- 
chihuital, from South America, which Mr. Squier had exhibi- 
ted at the Lyceum, and from any published description of the 
mineral. 
One of the specimens, cut in the shape of a ball, was trans- 
parent, of a yellowish green color, and was not touched by 
the file. It was set asa gem, and no further observations 
could be made upon it. The other specimens were of the 
white variety streaked with apple green, and resembled the 
Chalchihuital. It appears from such information as can be 
gathered from those who have been in China, that the real 
Jade is a gem of great value, and that the Chinese who come 
in contact with foreigners, are in the habit of selling any 
white or greenish stone under the name of Jade, if they can 
get a purchaser, under that name. Hence arises probably the
