An enormous electric magnet has

wald. The cas- Is formed of twenty
eight iron plates bent into horseshoe
shape and connected by rings 50 as TO

weight about l.40o pounds.
The Rev. DIR. McCook has noticed a
black carpenter ant" which is cap
able Of effecting great destruction in
woodwork, contrary to the general
belief that ants outside Of the tropics
are harmless practically. lie has seen
q rafter in which this species. the For
mica Pennsyluanioa, had penetrated TO
an extent of five OF six feet of its
length. completely honeycombing it. 1t
is evident that such penetration Of
wooden structures, and especially
bridges, might cause their disastrous
and unexpected fall.
One Of the most decided impressions
which non-scientidc people must re-
ceive from the visit OF the great comet
Of 1881 Is that OF the ignorance Of
science concerning these mysterious
yisitants. Whence they come OF
whittier they go are problems none can
solve; while the unfulhiled predictions
OF the return Of certain comets show
that calculations in relation to the mo-
lions Of those bodies partake much Of
the nature of guesses. With all the
skin and telescope penetration OF our
ASTRONOMERS, they cannot yet trace the
course of the comet, which in a few
days passes across the Unreasonable
expanse OF space viewed from this earth
and disappears 10 the depths beyond, to
wander perhaps for thousands Of years
before completing the cycle OF. its jour.
ney and returning TO point IN its orbit

Statistics show hat in the use Of
chloroform as an anaesthetic one death
C In 1878 cases, with ether one in
23.204, while bichloride of ethylene
nj one death in 5000 cases. with
this danger from the ordinary use of
anaesthetics in view, Messrs. o. de
Stefanis and Vachetta have proposed a
modified method of application, from
which excellent results have already
been reported, both with men and ami
mails. Their plan consists in causing
congestion of the nerve centres and
stimulating the heart 30 that 1t may
resist the noxious effects Of the anaes-
thetic agent, without diminishing in
sensibillty. For this purpose they en-
ploy alcoholics. They have studied
this method carefully In a large number
Of experiments, and have become fully
convinced that most of the danger and
much Of the Inconvenience resulting
from the use OF a~naesthetics may be
avoided by placing the patient slightly
under the influence Of alcohol.
In a recent paper Mr.. C.Shaler Smith
has given the results Of extensive OBJ.
servatons in relation to the pressure
exerted by the wind. The most violent
storm recorded by him was at East st.
Louis, in 1871, when the wind over
turned a locomotive, the maximum
force developed in SO doing being no
less than 90 pounds per square foot. At
st. Charles, in 1877, a Jail was destroyed,
the wind force required being "a pounds
per square foot. At Marshfeld, in
1880. a brick mansion was leveled, the
force necessary being IS pounds per
square foot. Below these extraordinary
pressures. Mr.. Smith instances numer-
Gus cases Of trains blown off rails,
bridges, etc. blown down by gales of
wind Of "a to 81 pounds per square foot.
In all the examples the lowest force
required to do the observed damage has
been taken as the maximum force of
the wind, although. of course, it may
