REPORT OF CHEMISTRY AND EXPERIMENTAL PHILOSOPHY.

R. TADDEL inas discovered that cor- 
rosive sublimate, when mixed with 
gelatine, is innoxious, the former to the 
latter being as 1 to 12 in dry, and 25 in 
fresh, gelatine. 
The present dip of the magnetic needle, 
according to the experiments of Capt. 
Edward Sabine, in the Regent’s-park, on 
the north-west of London, is 70° 3°; which, 
compared with the experiments of Mr. 
Cavendish in 1776, and Mr. Nairne, in 
1772, shews an annual decrease, since 
about 1774, of 3’.02: these latter, com- 
pared with the experiments of Mr. 
Whiston, in 1720, show, in this earlier 
period, an annual decrease of 3'.05 in 
the dip. 
M. Brandes, a foreign chemist, has dis- 
covered, that 2 parts by weight of salep, 
dissolved in 192 parts of distilled water, 
to which is added, 3 parts of calcined 
magnesia, become a permanent jelly, not 
subject to putrify; which is insoluble in 
water, fat oils, oil of turpentine, alcohol, 
or a solution of caustic potash. Quere, 
might not this singular new substance 
prove useful for covering the inking rollers, 
now almost universally used by printers, 
instead of leathern balls ?

kept at Hartfield, by Dr. F. Forster, from 
Nov. 20 to Dec, 20, 1822, inclusive. 
Nov. 20.—55° 29.55. Wind S.W. 
Clouds, with wind, and wetting fine show- 
ers. I noticed to-day the white polyan- 
thus narcissus (N. Orventalis, or Tazetia, ) 
in flower in the open ground. ‘Tussilago 
fragrans also in blow. 
—. 21.—43° 29.70. Fair day, but that 
sort of raw feeling in the wind which fore- 
bodes rain, Grey evening. 
—. 22.—52° 29.55. Early in the morn- 
ing I saw the counterpart of the phenome- 
non witnessed on the 2d of November. 
Beds of cirrostrative clouds, which were 
deep red by refraction at sun-rise, immedi- 
ately at the vapour-point changed to a fine 
golden yellow. Rain and wind followed, 
verifying the termination of the proverb 
before cited, that, un evening grey, and a 
morning red, will bring rain to wet your head. 
Aratus, the meteorological poet, also no- 
tices this red colour of the clouds as a sign 
of wind and raiv,,in his poem of the 
Diosemeia. ; 
—. 23 to 30.—Changeable damp showery 
weather. 
Dec. 1.—45° 99.92. Wind and rain 
from the south, A vast number of summer 
plants still remain in flower here and 
there : among others, Lychnis chalcedonica, 
Narcissus Orientalis, Chrysanthemum coro- 
narium, C. Indicum, Tagetes ercecta, Calen- 
dule officinalis, Vinca minor, besides holy- 
hocks, stocks, and others. The field- 
hares begin to be seen, and starlings still 
move about the country in large flights. 
—. 2 to 15.—Clear mornings, Fair 
days, and rain and wind all the nights, 
remind us of one of the complimentary 
lines addressed to Cesar. Nocte pluit tota 
redeant spectacula mane, Divisur imperium 
cum Jove Cesur habet. 
—. 5.—37° 29.65. N.W. Aclearday, 
with cirruli, and fairer prospect of fine 
weathier. 
—. 6,—49° 29.95. A fine clear day, 
and cold clear frosty night. The stars 
particularly bright, and the phenomena, 
conimonly called twinkling, very ap- 
parent.* 
—. 10.—The air became frosty, and 
the barometer up at 30.29. Ther. 29°, 
This was a fine morning, for the scent lay 
well: a circumstance which, as I have 
discovered, may be easily ascertained by 
those who smoke: if the smoke from the 
pipe remains stationary in the same place 
in the air, we may be sure that scent will 
lie well that day. 
—. 11, A wetting fog early. Barom. 
50.40. At night I noticed that the 
spectrum of Jupiter, in the field of a very 
bad non-acromatic telescope, was not 
oblongated and coloured as usual, but per- 
* I beg leave to call.’the attention of 
astronomers and meteorvlogists to the re- 
markable and sudden alternations of co- 
lour which attends the twinkling of stars, 
particularly the red stars, and especially 
Antares. This phenomenon has never been 
explained, nor much attended to; but it 
must have considerable influence on the 
refraction of the light of the star, thus 
varying the apparent position of the 
spectrum in the field of the telescope.
