THE average depth of the ocean is 49,
600 feet, and the average elevation of the
land is 1000 feet; therefore the total
volume of water in the sea is thirty-six
times that of the land above the sea.
THE suggestion made by the journal
Of the Telegraph, to designate message

appears to meet with favor in the English
electrical journals.
In the Canton de Vaud, Switzerland,
five walled tombs have been discovered

SoFTENING of the brain is produced

should be dispensed with as pigment,

THE history of chemistry is full of in

/ from the Arabic word chiDi0, signifying

ACCORDING to G. Marchand (Bied.
Cent?, 1872, PIP. 769-770) the usual
composition of human milk is as follow:
Butter, 36.8; lactose, Ill; protein, II;
salts, 2.04, and water, S73 parts per
! 1000. When the amount of butter rises
to above 80 parts the milk is injurious to
the child The quantity of protein,
which is much less than in cows milk,
can not be exceeded without ill-effects.
BRoMINE is likely to go into extensive
use as disinfectant, now that it can be
! had III solid form, or, more strictly
! speaking, as n compound which readily
! yields the bromine, and which can easily
be transported. A Prlssian chemist has
hit upon the happy idea of causing bro
mine to be absorbed by siliciois mari or
the shells of infusoria which has been
employed to take up nitro-glycerine in
order to make dynamite.
A RECENT report on injurious insects
states that the popular idea that grubs
are killed 10y extreme cold is not borne
out by facts. An examination of the
larvae and pupe that had been fully ex-
posed to the influence of frost showed
that they were uninjured even when the
earth containing them was frozen so hard
that the mass had to be broken with n
hammer. Frost, then, instead of dimin-
ishing the number of insect pests, has q
tendency just the other way.
