calcium, copper, iron, lead, potassium
and sodium.
Oysters come nearer to milk than all
most any other common food material
as regards both the amounts and the rel

1t is somewhat singular that, notwith.
standing the great advances made in

NJ. Bourdeles, Chief Engineer o
French lighthouses, has perfected a sys
EN- by which he can project a force o
$500, 600 candles by means of four lense
instead of twenty-four, as previously
and by a novel system of rotation make
the clash every twenty seconds. This,
the inventor claims, is the finest result
yet achieved anywhere.
Electric light baths are among th
latest inventions. The necessary part
of such bath are a cal let which will
inclose the entire body except the head
and fifty electric lamps of sixteen candle

body in groups, with a separate switcl
for each group. The light is thrown OF
a section at a time, making the patient
