HEALTH of LONDON during the WEEK.

(From the Report of the Registrisr-Generfti.).

The last week has witnessed a great improvement -in the
public health. The deaths in the metropolitan districts,
which had ranged above 1,400 in the last three weeks of
March, fell in the week ending last Saturday to 1.059. But
this is still a high rate of mortality, not only as compared
with what prevails in country districts, under conditions
more favourable to health, but also with that which the
population of London usually suffer at this period of the
year. In none of the ten corresponding weeks of 1841-50,
w,th the exception of that of 1850, did the number of
deaths exceed 1,028, while the average of these weeks was
946, which, if a correction be made for increase of popu-
lation will become 1,03 Compared with the latter e3ti-
mated result, fhe deaths registered last week show an in-
crease of twenty. seven.
A decrease in the mortality from complaints which have
lately been prevalent is now perceptible. The zymotic or
epidemic class of diseases, which comprises hooping-cough
and influenza, with nineteen other forms of malady, has de-
clined from 245 deaths, which it numbered in the previous
week, to 180 in the last ; the class of diseases of the respi-
ratory organs, from 272 in the preceding week to 220 in the
present return. The tubercular class, which includes scro-
f. la, tabes mesenteries, phthisis or consumption, and hydroce-
phalus, has remained nearly the same in the two weeks;
while complaints of the digestive organs show precisely the
same amount.
Last week 95 persona died of bronchitis, 81 of pneumonia,
24 of asthma, only the first of these diseases showing more
than the usual fatality; 59 children died of hooping-cough,
which is more than the average of corresponding weeks.
The cases in which the fatal cause is specified as influenza
have now sensibly decreased ; the number in this return
is 23. . .

The progress and decline of influenza during the last six
weeks may be traced in the deaths registered, which tere
successively 8, 15, 38, 65, 37, and 23. The fatal effects of
"diseases of the respiratory organs" (phthisis not being in-
cluded in this category) may also be traced during the same
period in the following weekly numbers :-281, 321, 352, 350,
272, and 220.
Small-pox has further declined, and last week the deaths
of only 7 children and two adults are ascribed to it; measles
also exhibits a more favourable result; and only 6 fatal cases
of scarlatina are recorded.

A GREAT DISCOVERY.—We saw, some weeks ago,
in a Pennsylvania paper an anni.uncement that a motive
power had been discovered to supersede the use of steam.
It is said that some facts have recently come to light which
entitle the statement to credit. Professor Salomon, of liar-
rochburgh, Kentucky, has suc..essfully applied the power of
carbonic acid gas as a substitute for steam in propelling en-
ginery tor every purpose. The power of this gas has long
been known to chemists, but their inability to regulate and
govern it has prevented its use as a propelling agent. Pro-
fessor Salomon claims to be able to control it with perfect
safety, and asserts that it will afford a pOwer equal to steam
in one-fiftieth of the space, and one-hundredth part of the
expense with both furnace and boilers. Experiments have
recently been made in Cincinnati, which are said to be en-
tirely satisfactory.— Nashville (United Stales) Banner.
BARNET CATTLE FAIR, LAST DAY.—This impor-
tant cattle fair terminated yesterday, and upon the whole
greatly to the ratisfaction of a large class of salesmen, who
succeeded in disposing of nearly all their live stock, if not
at high, nevertheless at remunerating prices. This fair is
held chiefly for the sale of young beasts to be laid down in the
grazing counties throughout England for future conditioned
purposes, when they are transferred into the several markets
both in London and the provinces. There was a current call
during the last of the fair for-Welch and Irish steers and
heifers, and only a few were left unsold ; milking and down
calving cows maintained high prices throughout the fair;
young horses were never known to be dearer, and were all
sold ; small ponies were in request, and fully maintained the
first day's prices.
