The lime used in the purifier being transformed
into carbonate Of lime, single cacination restores
il again. so that the same may be indefinitely used,
which s not the case when used for coal gas, since
in that gas absorbs no. only onc, but suphyd
acid also The price of coal gas Paris is ten
cents cubic mstre tabout thiYty.eisht cubic
feet the cost OF fabrication Of water-gas is
u cents If these results have been carefully
observed and proved they will attract much asten-
ton. The importance Of the interest engaged in gas
making may be understood By knowipg that in the
city Of Pans alone 100 eco uns of btumnous coal
yearly used in that manufacture producing twenty
five millions of cubic metres of gas, sufficient for
eightyh i've thousand asburners. Coal gas has dis
advantages which water gas hasnot- 1t is unhealthy

produces not only water but carbohic acid and often
contains sulphydric acid 1t is destructive, because

Rising of the Earth in Scandinavia
We read the following in paper communicated by
Mr.. Nilsson: rock in the sea port Of Fellbaeka,
called Gadmunds Schare, and situated lat. $50 s.,
was, in 1884, two feet below the surface Of the wa
ter in 1862, it was only inches under it in l742
IL had risen feet above and In 1884, 1t had an ele
vation of feet above the sea- There has been,
consequently, an elevation of feet in three centu
ries, or foot every fifty years.
Freezing of Vegetables.- Contrary to
general opinion, freezing is not necessarily desruc
tive Of life in vegetables At Charles Island, in
Hudsohs Bay, according to Captain James, the trees
had 10 be thawed BY fire before they could be cut
down, and there IL no doubt that the roots are az
we'll frozen as the stem since vegetation prospers
in Siberia where the following observations have
been made we'll was dug 400 feet deep, and the
temperature at so feet ls0 Fahr at " feet l9o
at Il9 feet 220 at 500 feet 49, at $50 feet 3D. Al
this place the soil 10 frozen to the depth OF 400
feet the cold reaches So below zero and the mean
temperature of the two winter months is 400 below
zero. During the l2S days during which there 10
Frost the strata of eternal ice are never hawed 10
a greater depth than feet.
Economy IN Cattle Grocing. The food
necessary to sustain animal life has to perform,
among other functions, that of developing, by its
combustion in the lungs, certain quantity of he at
The colder the surrounding atmosphere the more is
expended for that purpose Hence the ques-

RESEARCHES in Terrestrial Physics. Prot.
H. Henessy has brought the higher mathematics to
bear upon various questions connected with the
changes In globe cooling from fusion. In the
of his paper the author shows that The sodi-
hcaton of the earth could not have begun at tins
center but must have gone on from the surface, ad
ding successive layers of cooled rocks. He infers
that the least possible thickness OF the crust is IL
miles, and the greatest possible thickness 800 miles
He nfers also that considerable amount OF friction
and pressure must exist between the shell and nnid
nucleus.
Indian Hail Storm.-The following &C.
counts have been collected by DR.. Buist of ombay
Within the tropics, hail storms frequently occur al
attitudes Of ECO feet and upward they are mos
frequent in April and March. At Kotah, on the 5lt
OF March 1927, the hailsonss were large as man,
fist. Men, animals and birds were killed in the
village OF Nanda alone, six persons were killed and
seven dangerously bruised. At Serampore, in Apri
1879, the haistones were as largo as hens eggs and
consisted Of coats like an onion. At Kamptes, in
April 1881, there were haistones twelve inches In
circumference i've persons were killed. At,Be
Mares In February 1886, some of the masses of ice
which fell weighed two pounds. At Dunn DUN
April 1886, two haistones picked up OF sixteen
inches circumference, more than Ave inches in d.
smeter. At Gwabor, in February 1850, pieces of ice
fell nearly two pounds in weight, and animals and
men were killed At Condweil, 7th April 1850, some
single hailstones were as large as cocoa-nuts.
Bloping Engine Working at High Ve-
Oeity.-since the application of the double acting
movement, introduced fifteen years ago, up to the
present time the blowing engine has remained with
out essential improvement. 1t Is, however, a cum
brous machine, with slow notion Mr.. Archibald
Slate, an Epslshman, after series OF experiments
has arrived at the conclusion that quick motion may
be substituted with marked adv in the cost Of
establishment and in economy of eombustible mate
ria to obtain given effect. In a hrst experimen,
with a cylinder nine inches diameter and one foot
stroke driven at the rate of 80 revolutions per min
ute, he discharged the air at the rate of 81 pounds
pressure, through orince Of II inch II has been
submitted to the Institution OF Civil Engineers and
has been approved, with the statement that il 70
duces the expenses of machinery for blowing fur
mace sixty five per cent, and that an engine OF this
kind could be erected for f5o0 as well az one on the
old plan for fl 800, to do the same work.
Protection Of Timber against the Sea-
Worm.-Timber exposed in marine works is bored
by the teredo, whose head is arned or that purpose
and It is soon reduced to the appearance Of sponge
Worms three feet long aud one inch dia meter have
been found in piles Of hf, their favorite wood At
Southampton, piles of II inches square have been
eaten down to inches in four years. Experiments
have been mace by Mr.. Brunei and others to pro-
tect the wood By creosoting it, and their efforts have
