6. Movements of the Glands of Drosera; by A. W. BENNETT. 
A paper read at the Bradford meeting of the British Associa- 
us, the leaves do much mor a 
that. As well in D. rotundifolia as in D. longifolia, the end of 
the leaf folds over upon the base, or nearly, like a shut hand, thus 
fairly enclosing the captive. Plants showing this daily were grow- 
ing, in wet moss, in our class-rooms through the summer. When 
we published Mrs. Treat’s account of this infolding of the leaf, in 
is Journal, in November, 1871, and afterward in How Plants 
Behave, the discovery was thought to be new. But we find that 
the infolding of the leaf, as well as the intrusion of the glands, was 
discovered by Roth in 1779, and published by him in his Beytrige 
50-66

In the report of Mr. Bennett’s communication, given in 
Trimen’s Journal of Botany, and elsewhere, no allusion is made to 
the history and record of all these discoveries. But as Dr. Sander- 
son, in a succeeding communication, re erred to this last point as 
one which had been clearly made out by Mr. Darwin, It 1s as well 
in the same man- 
ner; but to a particle of chalk or wood they remain nearly in- 
different.” (How Plants Behave, p. 44.) : 
We have for several years been urging Mr. Darwin to publish 
the results of these and other (some of them still more curious) 
observations and experiments upon Drosera and Dionew, A. G._ 
. Fly-catehing in Sarracenia.—Referring to our note on this 
topic in the August number, p. 149, we have, first, an oversight 
to correct, For “ Mr. Hill of North Carolina,” read Mr. B. F.
