testing works of mattrasse-naseines, laid down ac-
carding to the modern practice in Holland by Dutch
contractors, brought purposely to Kieff by Mr. Vig-
neles. It is expected that the whole of the masonry
will be completed by the end of the season of 1850,
nod that in the course of the autumn of 1851 the
Kieff suspension-bridge will be finished and opened.
The causeway approaching the Dnieper from the
northward, as before mentioned, having been greatly
damaged in the great floods of 1845, will be put into
sufficient repair for the roads on the left bank of the
river. On the right bank, a fine new road along the
shore at the foot of the acclivities leads up stream to
the commercial and other parts of Kieff, and down
stream to the present ferry and the lower fortresses.
Another road will be formed ascending to the great
military positions on the heights above.
The beautiful model of this remarkable bridge is an
a scale of about 1 100 of the length of the actual
work. It is the most perfect thing of the kind, pro-
bably, ever designed or executed, and reflects the
highest credit o❑ Mr. James, of London, the modeller,
and his chief assistant, Mr. Sims, who, with another
engineer, came purposely from London to erect the
model at St. Petersburgh. Every piece of wood or
iron, every bolt, screw, and plank—and they are there
by thousands—is represented in miniature and in the
most perfect manner; the architectural details of the
masonry, the interior arrangements of the abutments,
the moorings, and saddles of the chains, the machinery
of the swivel-bridge,—all are faithfully represented
on the proper scale, and in due proportion. The
proportionate scale of length being as 1 to 100, that of
area is of course as 1 to 10,000, and that of cube as 1
to 1,000,000 ! and all the smaller pieces of iron are
accurately put into the model in the latter proportion.
The stand far the model is of mahogany, sup-
ported on bronze lonic pillars, with gold capitals
and frieze, forming a splendid piece of furniture,
worthy even of the Imperial Palace. The water of the
Dnieper is represented by a mirror, which reflects
the under side of the platform, and the whole model
is covered with a splendid glass case, set in a gilt
frame, with a beautiful dome of glass, supported on
richly gilt pillars of the Corinthian order; the whole
exquisitely chased. The model and stand have re-
quired two years to make, and the expense from first
to last has been fully 6,0001. sterling.
The cost of the Kieff suspension-bridge, exclusive
of the approaches, will be upwards of 400,000 guineas,
say about two millions and a half of silver roubles of
Russia, and nearly 11,000,0001, which though large
in amount, may be considered a very low price for so
large a work. Mr. Vignoles has already prepared, by
command of the Emperor, designs for several other
large bridges in various parts of Russia. Some of
them have been approved, and others are still under
consideration, and designs are i❑ various stages of
progress for still more bridges, besides other works ;
for all of which the iron must be furnished from the
English manufactories.

HEALTH OF LONDON duriv the WEEK.
(From the Registrar-General's Return.)
In the week ending last Saturday the deaths re-
gistered in the metropolitan districts were 1,053.
The weekly average of this season, corrected for
increase of population, is 1,162. The mortality of
last week is therefore less than the estimated amount
by 109 deaths, and is nearly the same as that of the
previous week. Of the 1,053 persons whose deaths
are included in this return 841 had medical attend-
ance, and written statesments of the diseases which
proved fatal, distinguishing in many cases the pri-
mary and secondary forms, are entered on the
register books ; 15 had no medical attendance. In
15 cases the causes of death were not certified, and
in these it does not appear whether or not the patients
had professional aid. At the end of the quarter an
influx of cases returned by coroners swells the num-
ber of deaths registered in the week, but many of
these occurred at earlier dates. Inquests were held
on 176 deaths in the present return, considerably
more than the due proportion. They fall mostly
under fractures, wounds, drowning, hanging, and
suffocation, burns, scalds, and poison, making
altogether 65, whilst the weekly average is 30; and
under apoplexy, from which there were 44 deaths,
whilst the average is 26 ; besides 45 in which the
cause of death could not be ascertained, or was
defectively returned, the average of such being only
12. Seven children are returned as having died of
suffocation in bed ; 5 deaths are ascribed to intemper-
ance, of which one was the case of a girl of fourteen
years, who died after 38 hours' illness of congestion
of the brain and other organs, from drinking gin ;
a child died of want; a man of 40 years, in the
subdistrict of St. Andrew's East, of "exposure
to cold and destitution," and a pork•butcher of 27
years, on the third day after admission into the
workhouse of St. Martin's-in-the Fields, from the
effects of "starvation and neglect." A woman who
had no medical attendance died in Somer'se town of
" inflammation of the lungs ;" she is stated to have
arrived at the advanced age of 100 years. In the
last week 42 children died of measles (which is about
the average), 24 of scarlatina, and 24 of whooping
cough (both diseases now under the average). Small-
pox, which was fatal in seven cases), and typhus in
31, are also less prevalent than usual. There is a
decrease of deaths on the previous week both from
bronchitis and pneumonia ; eight persons died of
influenza. Only nine deaths occurred from diarrhoea ;
none from cholera. Tables accompany this return
which show the deaths from cholera in each of the
135 sub-districts of London in each week since
October, 1848.
The mean daily reading of the barometer at Green-
wich Observatory ranged from 30'440 inches to
30.304 inches on Sunday and Monday ; on Tuesday
it was 30.378 inches. The mean of the week
was 29 877 inches temperature of the week
was 83.1 degrees, less by 9 degrees than that of
the previous week, and less than the average of the
same week in seven years by five degrees. The daily
mean was throughout less than the average, except
on Wednesday. On Friday, when the mean tempe-
rature was only 25 degrees, it was less than the
average of the same day by 13 degrees.
