Tn recent lecture, Pro-. Edward
Fran. lin stated that six millions OF
I tons of coal are probably burned i'll
Lqndog during the winter months,
and the quantities Of steam, SCOT, tar
and sulphurous acid discharged into
! the air as products OF this combustion
i are enormous. These products unite
. to form tho London fogs. Steam sup
! plies the basis OF all fog, and the vapor
!. particles become covered with tar,
which renders them more permanent;
dirt is necessary 10 produce fog, while
i sulphurous acid promotes it. DIR. Frank
land illustrated these points by expert
+ ment. To prove the effect Of dirt iii
, the air he filed large flask with moist
/. air freed from dirt by fltcring, then
cooled the flask, when slight mist
was formed which disappeared in a
moment; repeating the experiment with
air containing its normal charge Of dirt,
the fog was much more dense and last
ing. larry matters render fogs per-
: sistent by retardiug evaporation. He
believes that the general substitution
Of anthracite for hituminous coal would
do much toward freeing the metropolis
from it's foga, as tho discharge Of tar
and SCOT into the atmosphere would
.4thus be vastly lesscncd.
A very general idea is that ten
dency to certain disc is indicated
by certain types Of faces, as is shown
BY the frequent use OF such phrases as
"consumptivo looking" The subject
has been investigated by Drs. Gallon
and Mahomed, whose conclusions thus
far fail to support the belief that GER
tain physical characteristics prove a
special liability to consumption or other
disease, although it may perhaps be
shown that the effects of the disease
when commenced may be influenced by
such.
Prof Boyd Dawkins, in depicting
the appearance Of the world before mar
recently described America in the 60
Gene and miocene periods as being. con
nectcd with Europe BY heavily wood
ed barrier Of land stretching past the
Farce Islands; while the alligators ane
fishes of Europe were indistinguishablt
from those Of this continent.
(. Seasons Of low water in the lakes o
Switzerland offer favorable opportuni
ties for adding to our knowledge of tn,
ancient lake-dwellers. The water o
lake Constance has lately been lowe
than at any other time since 1905, an,
advantage has been taken of it to ex
anime number of lacustrine dwellings
with the result OF numerous discovcrie
of implements.
During an address by Prof w. i
Ayrton on the storage of power th
lecture theatre was lighted, circula
saw was driven and an elevator opel
ated by means Of electric energy whic
had been stored the previous day i
Fauro accommodating batteries. Tn
total quantity Of energy was $4,000
900 foot pounds little more tina
twenty-five horsepower exerted. fo
ono hour. A single cell, containin
81 pounds Of lead and red lead, is foun
to store l,44o,oo0 Ioot-pouads Of er
orgy.
Il has Been proven by direct con
parison that objects which are whit
BY sunlight appear yellowish under tn
electric light, and red when seen b
electric light. "The Illusion" says u
Werner Sicmens, ..arises from our b
ing accustomed to see the earth rcil
illuminated after sunset, and ON til
basis forming different scale Of colol
for ourselves. Daylight would, accor,

An interesting experiment is said
have been made with hibernatil
hedgehog, in which tie brain Of Il
sleeping animal was removed, then Il
entire spinal cord, but for two hou
hardly any change was noticeable
the action Of the heart; and a day afte
ward that organ contracted whe
touched by the operator.
The largest trees known are prob
bly, = Eucalyptus amygdalina, or "pe
permint tree" growing in the Dand
nong district Of Victoria, Australi
which is said to measure $40 to Il
starting point of the crown, and 4
feet to the top, and another specim
Of the same species, mentioned by Bs
on Ferdinand Won Muller as havi
attained the height of4so feet.
