Dry rot.— Butters? describes the destruction of pine paving blocks in 
Birmingham, England, by Lentinus lepideus Fr. This fungus produces a dry © 
rot which in its microscopic and chemical aspects resembles the destruction — | 
hadromal is left behind. The ravages of the fungus were somewhat chec ed 
by a dipping in creosote which the blocks had received before being laid down. 4

Self-digestion of endosperm—Ponp summarizes’; the literature on this 4 
point, and finds no clear proof that the amylaceous endosperm of grasses or ' 
the horny endosperm of palms is capable of self-digestion, though this has been — 
claimed by authors and the claim has been accepted hitherto. He himself care- — 
fully tested this point in the seed of the date, Phoenix dactylifera, and finds” 4 
its endosperm incapable of self-digestion—C. R. B. 
Formation of chlorophyll.—According to PaLiapIN this is a process of a 
oxidation, dependent upon the presence of sugar solutions of low concentration = 
and is not inhibited by concentrations of even 30-50 per cent. sugar in detached 
leaves of Vicia Faba.—C. R. B. 
Caprification—Lonco has been investigating the fig and caprifig, and in _ 
advance of the full memoir with illustrations has published a brief preliminary — 
announcement.5s As the differences from previous accounts are those of detail — 
rather than fundamental in character, a review will be deferred until the appear- 
ance of the full paper—J. M. C 
Anatomy of Epigaea.—The histology of the stem and leaf are described

glandular hairs on the lateral pan iN the suggestion is made that these 
aid in absorption of food.—M. A. Cur
