queathed by Mr.. Richard Berrige for

tary science in Great Britain.
But few people have any idea of

Of the electric lighting business in this

Professor Edward Hull. director of
the Geological Survey of Ireland, in. a
paper read before the British Associa-
ton at its last meeting, says that many
geographers have overlooked the effect
of continents in attracting the oceanic
waters adjoining them. He thinks that
the attractive force of the land piles up
the water of the ocean all along the
great continental coasts.-M. 7. Ledger.

"A man in Mexico, who was struck
by lightning and was supposed to be
dead, was restored to consciousness by
means of large quantity of cold water
which was thrown over him at the sug-
gestion of passer-by. 1t served to re-
establish respiration before the paraly-
sis of the heart had become absolute,
and the patient recovered. In an ac-
count OF the case, communicated to the
Mexican Academy of Medicine, it is
stated that the effect of the electric
shock on the system was very much
like that of an overdose of chloroform

From many observations on healthy
men, DR.. Theodoroff, of St. Petersburg,
learns that the vital capacity of the
lungs increases from morning till even
ing, decreasing again during the night.
After each meal, too, there is special
increase, followed by slight decrease;
the vital capacity being at its highest
shortly after dinner, and at its lowest
after getting up in the morning. The
force of inspiration and expiration fol-
lows nearly The same law.-ArkansG Gw

"A report based upon an inspection
Of 1,214 factories in 1875 different
branches of work in Russia states that
the hours Of labor there vary from six
to twenty, and that in one or two special
instances workmen were compelled to
labor twenty-four hours uninterrupt-
edly. These differences are purely az
bitrary and not controlled by the kind
of work. In the same district in
the same sort of work there is some
times q difference of eleven hours in the
amount of work required in day in
the different factories. E,
