A curious failure OF sensitlzcd paper
and dry plates Is reported BY Liesegans.
The materials being proven OF the
usual quality, It was suspected that
ncetyleac, with which experiments were
being made In the neSt'ro0m, was the
cause; and this THEORY was found 10 be
correct Neither hydrogen nor coal gas

The home OF the Chinese tea plant is
now believed to have been Upper As

gion was not generally known until 1894
Prot A. Krassnow, OF Kharkotf. Rus

must be indigenous to the whole mon
soon region OF Eastern Asia. Us he has
found 1t growing wild In dense, uncut
tlvated forests as far north as the Is
lands! OF Southern Japan. He believes
that 1t existed In China and Japan long
before the cultivated form wins intro

OF cultivation having been too short to

Of the Chinese plant have resulted from
changes Of climate OF Eastern Asia
since the tertiary epoch, Instead OF from
cultivation in colder climate or from
exhausted soil:- He traces the two vnr-
ietea-Assam and Chinese--to remote
times, finding the first still growing
Wild In india and the other occurring
still Wild in Southern Japan.
