The migration of birds Is being
studied In a new manner by German
ornithologists. Hundreds or thousands
of crows are being captured at Rosslt-
ten, in East Prussia, and, after being
tagged with a number and date. are
again liberated. 1t Is requested that
when one of these birds is killed, the
tag and date and place of killing shall
be forwarded for record.
Some mysterious deaths Of cattle in
Attorney have been traced to a curl
Gus source. Mercury was found in the
dead animals, and also in many mead
ows and gardens, and the presence OF
the poison is attributed to recent ex-
ploslon Of a factory for illuminate OF
mercury. The fumes from the explo-
sion were carried to a distance by
strong gale AS result Of the inquiry,
the manufacture of explosives In the
island has been prohibited
A still unexplained effect of the cleo
trio light somewhat resembles mild
sunburn and sunstroke. The heat of
the electric arc employed in the re-
ducing furnace is so concentrated that

ly affected. Even at this distance from
the heat, however, persons experience
a burning of the face and other ex-
posed skin much like that produced by
intensely hot sunshine. The skin be-
comes deeply bronzed and there is
temporary blindness In natural light.

It is maintained that 1T does not differ,
except In the manner OF lis origin,
from that extrac ted from the camphor
trees Of Formosa. Artificial camphor
Is made from essential oils derived
from turpentine. Chemically the only
difference between turpentine and
camphor Is the possession by each
molecule of the latter of one atom OF
oxygen which is lacking In the former
BY chemical process the needed oxy
gen is supplied. Three-fourths of the
whole supply of camphor Is used in the
arts. and one-fourth In medicine.
