BERNARD adds his name’s to the increasing list of those who are unable to 
btain evidence of photosynthesis outside the organism. Using various methods — 
he “obtained no positive appreciable results.’””—C. R. B 
Lock"s has made some interesting observations upon a variety of Turnera 
ulmijolia that has become naturalized in Ceylon. The flowers are distinctly 
heterostylic and apparently absolutely self-sterile, and the pollinating insects 
are bees, notably Apis indica. The seeds are most commonly dispersed by the 
aid of harvesting ants—J. M. C. 
A NOTE in the July number regarding the experiments of KOERNICKE on 
radium emanations should have included reference to the experiments of DIXON, 
who found seedlings retarded in growth without serious injury. Experime 
on cultures of 48 species of bacteria by Drxon and WicHAM‘S showed inhibition 
of development, confirming the results of other observers.—C. R. B. 
Frres'® has published an interesting article on ornithophily in the South 
American flora, arriving at the conclusion that there is no distinct difference 
between ornithophilous and entomophilous flowers, and that the same species 
may be pollinated as well by insects as by humming birds in one place, while 
in another locality either of these agents may be acting.—P. OLSSON-SEFFER. 
INTERCELLULAR protoplasm in the cotyledon of Lupinus albus is reported 
by Kyy'?. This protoplasm does not seem to differ from that contained 
within the cells, except that it contains no nuclei, starch grains, or plastids. 
ipe seeds were used in the investigations. The behavior of the intercellular 
protoplasm during the germination of the seed will be described in a future paper.
