There is only the one way into the

innumerable. According to the report
Of the register-general of England for
1874 as to the cause of mortality in that
country, bronchitis heads the list with

answers fer $4,000; atrophy and debili-

Heart disease, apoplexy and paralysis
are increasing; cancer, too, is CROWN
more fatal, but consumption appears to
be on The decrease. There were twenty
five boys and men, nearly all following
outdoor occupations, killed by light
ming. There was a death from the bite
of fox from the bite of rat, from the
scratch of cat, from the bite of leech,
from the sting of hornet, and two from
the sting OF wasp. There were more
persons killed by horse conveyances than
by railways, the former being 1913 and
the latter l, 249; eighteen persons were
executed and II ,592 committed suicide
An English mechanic has contrived
to make a steam engine to do its own
stocking. a large sheet.iron hopper is
set above the mouth of the furnace and
in front of the boiler. This is the redep-
tacle for Goals. Below the hopper a
steel crusher is made to run some
what rapidly, and, as the Goals /.
fall by reason of their own gravity upon
this grinding apparatus, they are reduced .
to the uniform size of cobnuts by the
action of the crusher. Thence the
equalizad fuel drops upon pair of iron
disks, or fans inclosed in a box, and run
ming in opposite directions at high We
locity. The fans are, in fact, the furnace
feeders, for as the box has but one open
ing, and that leads TO the fire, they lit
orally blow the Goals into the latter and
distribute them equally over the whole
surface of the fre.bars The feed is
regulated in quantities according to the
,eavy or light work the engine may be
ioing, b.. means of a single adjusting set 4.

In regard to the use of chloroform in {

In the present state of pro- n
opinion upon the subject, the I

o great is the prejudice against this v

count, authorities are unanimous in in
