Dr. A. Rohde says that the use of do
mestic utensils made of nickel is quite
harmless. A nickel plate vessel with a
surface of 800 square centimetres. con-
tanning two per cent. solution of acetlc
acid, lost in twenty-tJur hours only from
| twenty-four to twenty-nine *mllllgrammes
of the nickel and tartaric, citric and Tactic
acids have all about the same effect On the
metal as the acetic acid. As such small
quantities of nickIe are dissolved even UNI

there can never be any real danger of poi

According to the Perseverance,, of Milan,
! important sponge banks have lately been
discovered close to the island of Lampe-
| dusa, on the southern coast of Sicily.

| equal distance from the southeastern ex-
tremity of the island The smallest
depth above these banks is twenty ellis;
the greatest depth is from thirty to thirty
ones ellis. At the lesser depth rock Is met
with. on which the sponge grows; at
greater depths sandy soil is found.
There were altogether about 300 dis
tinct epidemics of influenza in Europe,

other substances are treated in the same

Among the many startling contrasts be
tween the industries of one hundred years
ago and those of to-day, one of the most
impressive is the vast expansion of the
production of that indispensable article,
iron. A century ago, it is stated, only
charcoal iron was produced, and of that
only 5000 tons year. Even Great Brit
ain produced in 1850 only $500 tons.
To-day, there are several furnaces in this
country, each of which turns out a lnually
as much as that, and single railway now
| buys yearly more iron than both Great
Britain and this country produced cen
fury ago.
