The .Sanitarian suggests that the

substances which absorb foul gases.
This is, of course, merely one way of
purifying the air, but may be useful
whore fresh air cannot be readily or
safely admitted in sufficient amount.

As il consequences Of the treatment with
water and the application Of heat, the
starch grains, which in their normal
condition are little sacs filed with
minute granules Of starch proper, have
been swollen and burst.
HAVING explained the scientific prin-
ciples involved, Mr.. Mattieu Williams
gives in knorleiye these directions
for boiling eggs Take saucepan hold
ing pint Of water and raise the latter
to the boiling point. Then put an egg
IN the boiling water, place the sance-
pan on the hearth and leave it there
with the egg in it ten minutes or more.
An egg SO cooked, he says, will be ten
der aud delicate, evenly 50 throughout,
no part being hard While another part
Is semi-raw and Shiny.

used at various places. They are ia
vorcd not only by the range Of tide,
but also by the long estuaries of lrreg-

IT has been proved that under certain
conditions yeast may he powerful
poison. II introduced in suspension
into the circulation of living animals
to the extent of more than two
granimes. it always produces fatal re-
suits; in smaller doses it induces coma.
This is due to the fact that it multiplies
in the blood. depriving the red cor.
puscles of their oxygen and reducing
their color to dark brown. From
