SCIENTIFIC MISCELLANY.

The beginnings Of life have been lately
studied BY Miss Rlna MONT In some 81
the newer lakes Of the Alps, In the
Lake OF the Seracs. which has been form
ed within the memory of present In habi-
taHts, only i've species OF life are to be
found, ana these are all plants four be-
ing datoms. VA Ong and Tignaga, two
older lakes, animal forms feeding upon
the diat0ms-h9ve begun TO appear. The
observations make IL evident that life in
a lake begins with diatoms that absorb
the carbonic acid dissolved In the water,
and that the next stage Is the develop
ment OF simple animal organisms, Hike
rhizopods, that subsst on vegetable forms
already existing. biologists have in
fcrred that the first life on earth began
IN the ocean In this same way.

The new fiy of East Africa, described
by w. Donltz az Cordylobla Murium, was
discovered by DR.. Robert Koch as para
sites In the skin Of rats suspected OF
plague, Il lies Matched from the maggots
IN just one month. II Is supposed that
the eggs are laid In the earth and that
the larvae attach temselYes to the parts
Of the rats touching the ground, larvae
Of another fly Of the same genus are
found In bols OF railroad builders in
Guinea.

tail is almost submerged, while the for
