ordinary circumstances, indicates a
10 ger lease OF life than when the
lower limbs are long and the body
short. IN large, long body, the vital

EXPERIMENTS were recently made in
Berlin TO ascertain the effect OF gas on
the roots OF trees. The gas from the
street mains was delivered into the soil
in which TWO lime-trees and maple
were planted. After the lapse of two
months the roots were examined, and it
was found that all the fibers were dead.
The bark of the strongest roots were de-
cayed, and even the woody part altered.
The gas was then cut oft To see if the
trees would recover one of the lines
produced sickly crop of leaves, but
the other trees showed no signs of life.
DR.. HALLIER, well known by his re.
searches upon the fungi as supposed
agents or concomitants OF disease, states,
in recent paper. that measles and
scarlet fever are both occasioned by the
presence fungi in the blood, which can
be seen 10y the microscope in the form
of minute cell-lil<e pores, called micro
coccus. In the course of treatment Of
persons affected with the above diseases,
care was taken to collect the perspira-
ton obtained from the patients under
these circumstances, and which, on
being submitted to DR.. Halter for ex.
animation, was found to contain the
micIococcus in abundance.
