forms us that he published an account of his observations three 
years ago in the Carolina Farmer, published at Mabe See! and 
that this was copied into a Mtoneneniery peat a) paper, but h 
is not aware that it attracted further attention. The au thos of 
the ph ie referred to, in the English erunilant SH of Le Maout

statement steal e. In a recent letter, Mr. Brady gives an 
account of observations repeated last summer upon the pitchers of 
Sarracenia flava. “'These, brought into the house, and kept fresh 
the immersion of the base in water, showed ‘the saccharine 
junction of the lid with the rim. .... Many flies settled on the 
lids and feasted on the saccharine narcotic. Evident signs of 
intoxication were manifested in each case, by their breaking loose 
fst before tumbling into the gulfs 
Sarracenia Drummondii is the species which most closely re- 
sembles S flava in the shape and structure of the pitcher. We 
now learn from a letter addressed by Dr. Chapman to Mr. Canby, 
that the former is well aware of a similar excretion in that species. 
“On the inside of the hood,” he writes, “ above its junction with 
the tube, there is a very faintly sweetish secretion; scarcely per- 
ceptible to the taste, which is very attractive to insects; and, a I 
do not detect any of this within the tube, I wonder how it hap- 
pens that so many insects are ap hig e since they could easily 
y away from the open hood.” Mr. Brady’s observations are here 
to the point; but wider confirmation is desirable, especially as to 
the narcotic character of the secretion, which jneeds abundant 
evidence. And the other species should now be scrutinized.

for him more time to expatiate in hem. on the principle, “ to 
him that hath shall be given,” he well deserves it, as having 
accomplished far more in these rescued moments than others who 
could mainly devote their days as well as nights to scientific work.
