Ty Scrence of Feb. 29, Joseph F. James gives an interesting account of 
the expulsion of water from a Caladium leaf. A new leaf being ready to ex: 
pand by the side of an old one, the latter was cut off. Afterwards, from the 
stump end, jets of water began to be thrown to a height of an inch, and with a 
regular pulsation of about 180 per minute. This was kept up for two or three 
days, the rate gradually diminishing. It seems that other members of the 
Aroid family have been caught in the same performance, and in 1672 an ac 
count was published describing water expelled from the leaves of some aroids 
resembling a fountain. These large stories are always the oldest. 
Mr. Frank M. Day has published, in the proceedings of the Am. Phil. 
Soc., Philadelphia, a paper on “The Microscopic Examination of Timber with 
regard to its strength,” accompanied by four plates. It is a subject opened up 
recently by Dr. J. T. Rothrock, and developed by Mr. Day under his advice 
PAPER PRESENTED to the Royal Society of London, Prof. Alexander 
Dickson called especial attention to a series of remarkable glands which occur 
in the corrugated annulus which forms the rim of the pitcher of Cephalotus. Ti 
the inflexed rim of the pitcher be examined a number of openings may 
found, alternating with the corrugations of the annulus. Each orifice is con- 
tinued inwards as a canal-like fossa, at the bottom of which projects a nipple- 
shaped body. This body is the free apex of a gigantic gland, the bulk of which | 
is imbedded in the parenchyma of the annulus. These glands may be truly de-
