SoME interesting experiments upon
tho nature and origin Of tho light omit
ted by tho flrc-fly have been lately mado
by Prof. S. p. Langley. From the spec
troscopc no finds tho heat given out Is
scarcely apprcciablo. That tho light Is
a chemical product would seem to be cs-
tablishcd by tho fact that it decreases
by products which check combustion

ucts which aid combustion (oxygcn),
and that tho product of the process is
apparently carbon dioxidc.
IN a recent English reviow in nm arti-
Gle on "Dar~inism," tho author says that
the fundamental objection to tho theory
Is that it rests Upon on assumed fact
for which thcro Is no authority. "Two
white spots on distant hill appear both
alike; to US, ~ our distance, they aro
Ibatc spots only, while, In fact, ono is
n'block Of stone and tho othor sheep,
and there is no single point of rcsem-
blance oxcopt their color. Exactly so
the supposed simplicity of living germ
is not q fact of nature, but only tho OK
preston of our own blindness" .....
