1876. The recorded natural increase of
population was thus l25,268. Regis
tered number of persons married in the
quarter ending March 3lst, 1876, was
1890. The residen1 population Of the
united kingdom in the middle of 1876 is
estimated at 33,093, ,439; that of Eng
land and Wales at 24.244; of Scotland
at 9,627 ,Sl1; andof Ireland at 5,32l ,6l8.
At recent meeting OF the British as
sociation Mr.. Garner stated that he had
found the measurement Of brain capacity,
and from casts of the interior Of skulls
that the size of the brain Of the dog does
not correspond very closely with the size
Of the animal, No dog has SO large
brain as wolf, nor one 10 small a. the
jackal. The brain Of Newfoundland
dog is very little larger than that of q
terrier. Professor Macalister, Of Dublin,
gave an account Of the brain of the Gel
ebrated grey hound " Master Macgratb. +"
He had weighed the brains Of many
dogs, but Master .Macgrsth's was the
heaviest of sll, and the convolutions
were much more complex.
The geographical variation among
North American mammals, particularly
in respect TO the size, is treated of by
Mr.. J. A. Allen, in the bulletin of the
geological and geographical survey Of
the territories. He has ascertained that
most northern and arctic animals are
smaller the further southward they live
while the reverse Of this Is the rule as
to the southern animals. Mr.. Allen
formerly thought that the American
sable and common black bear OF this
country could not be distinguished from
European form, but he has now come TO
the conclusion that they are distinct
species. He thinks, however, that the
grizzly hear of America is what he terms
a sub species Of the brown bear Of Europe,
and our red fox is also regarded as q sub
species of the European red fox.
The formstion of nickel ores near
Lancaster, Pennsylvania, is pronounced
by the American manufacturer to be the
heaviest 30 far discovered In any part Of
the globe. The ore Ia exceedingly rich,
Of grayish tint, very heavy, and is 20
hard and closely united to the surrounding
substances that it has to be got out by
blasting. As soon % the ore is mined 1t
is crushed into small pieces, and then
transferred To kilns of capacity of from
eighty to ninety tons each. II is then
subjected to heat obtained at first by
burning wood, and which Is continued
by the conversion Of the evaporating
fumes. The manipulation Is concluded
by the fused metal being placed In .
smelling furnace and undergoing q pro-
cess similar to that adopted In the treat
ment ofiron-ore.
OF all the forms Of energy, gravity Ii
the one force whose relations with the
Others it Is most difficult to imagine.
Other forces affect each other most pal
pably; magnetism forsakes q magnet
when IL is made whitehot; chemical
affinity is most sensitive 10 variations OF
temperature, and even In some cases
to mechanical tremor; the transmits
sion Of electricity Is favored BY the COOL
ing Of 4 conductor, and 10 on. Other
wise is It with gravity: a given mass Of
matter. however mechanically moved,
electrified, magnetized, heated or sub
jected to chemical changes, at the same
point of the earth's surface, always
weighs the same. The only force with
which gravity has any analogy is mag
netism; and were magnetism always at
tractive, instead Of polar, with equal
opposite manifestations of attraction and
rcpulsion, the analogy would be strong
one.
The danger attending the use Of Porce-
lain lined cooking utensils was pointed
out at meeting Of the British society
of public analysts by Mr.. Talleck. He
stated that the milk-white porcelain en-.
amel with which cast-iron cooking vcs-
sells are now no commonly coated Is in
the highest degree Objectionable, on ac-
count of the easy action on it of acid
fruits, common salt and other substances
by means of which led and even arsenic
are dissolved out in large quantities
during the process of cooking. II was
shown that it Is not 10 much on account
of the presence oflarge proportions Of lead
and arsenic that these enamels are dan
gerous, but because they are 10 highly
basic in their character and are no read
lily acted on by fubby-acid solutions.
He thought that no enamel should be
admitted to use unless it was totally un-
affected by boiling with a one per cent.
solution OF citric acid, which was a very
moderate test. Further, he gave 1t as
his opinion that either the use Of such
poisonous ingredients AZ lead and arsenic
in large quantities should be entirely
discontinued, or that the composition
otherwise should be Of such q character
as to insure that none Of the poisonous
substances could be dissolved out under
ordinary circumstance"
