candlesticks without oil, invented, I believe, by Woomsron. A metal stem passes down into the liquid, and, once heated, is afterwards kept warm by the burning vapour, which it causes to rise and issue from the gas-jets encircling the stem. Some mystery is made about the liquid, but its analysis proves to be very simple.
Specific gravity, '76O at 32°; easily volatile. with a smell of turpentine. 100 grs. allowed to evaporate spontaneously, left barely a trace of solid matter—resinou_s. 100 parts, mixed with water in a measured tube, turned white, and 15 parts of pure colourless turpentine finally settled at the top of the watery emulsion. In fact, a mixture of 85 alcohol, and 15 turpentine was found to possess precisely the qualities of the liquid, burning with a clear flame, and without smell.
It is necessary to use the oil of, and not the rectified, turpentine, which latter is well known not to be soluble in alcohol.
5.—Native Remedy jbr the Spleen. The late Dr. Twmme gave me some pills used by the natives as a
cure for the spleen. They proved to contain nothing but sulphate of copper, mixed up with meal and mucilage. 6.—Three bottles of Water from Hot Springs in Assam.
Captain Jnnxnvs is anxious for the result of their examination ; but I really am uncertain of two, which arrived in a dirty and odorous state—one, No. 3, containing an abundant putrid yellow scum,which appeared like a compound of bitumen and sulphuretted hydrogen, but was not further examined. No. 1, was a clear sweet water, having a
specific gravity, '9964 at 91°, and containing only common salt. 7.—Mineral Water from Ava.
CAPTAIN Macnaon favoured me with a bottle of water from the lake near the Khyendwen river, whence a mineral salt is obtained. It hada spec. grav. of .9985 at 88°, and was consequently nearly pure. But a second bottle, filled from a well only three feet from the same lake, weighed l'OO06 at 88°, and yielded a copious precipitate to muriate of barytes, and nitrate of silver, shewing it to contain a mixture of sulphates and muriates, which are extracted by the people of the
The two bottles sent me by Dr. SPILEBURY were so nearly pure, that it was not worth while to examine them further than by the hydrometer.
The following are, I believe, the correct names of the specimens obligingly sent by Lieut. Fo1.sr, in June. Nos. 1, 4, 16, irom pyrites ; 2, galena; 3, sulphuret of antimony; 8, 9, hydrated oxide of iron, haematitic; 10, fibrous gypsum; ll, magnetic oxide of iron; 12, 14, 17, granite with pseudo-metallic mica ;l3, black oxide of tin. '
10.—Suh1huret of Molybdenum.
This was put into my hands by amercantile house in Calcutta, without however noticing whence it came.
It resembled graphite or plumbago so exactly in its qualities of drawing traces on paper, of beingiunaltered in the fire, and very gradually disappearing, that I should have been contented with these appearances, had not its specific gravity, 4'64 to 4'5, been so much higher than that of graphite, (l'4.) When heated also, white fumes, devoid of smell, or slightly sulphurous, were perceived at the moment of withdrawal from the fire.
It was digested with disengagement of red fumes in nitric acid ; leaving a white insoluble precipitate in the filter, weighing 744 per cent. The liquid gave immediate evidence of sulphuric acid, that had been formed from the sulphur present. The white mass acted in all respects like molybdic acid, and was known to be so from its peculiar property of turning instantly blue on contact with metallic iron, lead, copper, or silver: a fact, I believe, not hitherto noticed: water is required to produce this effect. Heated red with carbonate of soda, the metal was reduced with etfervescence.
I am not aware that IlllS singular mineral is turned to any profit, but it is desirable to ascertain where it has been discovered. The high specific gravity of the Ceylon graphite, 2'37, leads me to imagine that I may have mistaken that mineral also, and invites further inquiry. It may be remembered*, that in an English cabinet of minerals, a metallic ore was also found substituted for the true Borrowdale plumbago.
lX._Horary Meteorological Register for Calcutta. By Jas. Pnmsnr, Sec. &c.
The 21st September having been appointed one of the days for the combined series of horary observations, by the Meteorological Association, Icould not allow it to pass without an attempt to fulfil the prescribed terms, even at the sacrifice of a night's rest.
The weather was not very favorable, although such as might be expected near the equinox: the barometer was gradually falling, indicative of blowing weather; which in fact followed a few days afterwards. The occasional violent showers checked the course of the thermometer and hygrometer; and the minimum temperature noted, was that of the rain, rather than that of radiation to the sky. As a ditferent barometer was necessarily used during the night, care was taken to continue its readings during the day, to obtain an accurate comparison with the standard instrument at the Assay Ofiice. The difi'erence—'0l7, has been added, to bring the whole to terms of the

standard, which I have reason to believe does not differ more than -010 (in defect) from the Royal Society's barometer.
The thermometers were all standards from NswMAN’s. agreeing very closely together.
The diurnal tides for the two days are respectively 0' 140 and 0'1 16, from the former of which must be deducted the gradual decrease of the pressure for 6hours;"7H;32—__-_6_6L".-j-4:'01 7,leaving0' 1 23,and" l 10‘ + ' 123 +2 =0'l2O is the mean, which is rather above the usual amount of tide for the month of September. The nocturnal tide from 10% P. M. to 4% A. M. is '700—'6U7 (with allowance for the half hours) fr-‘O83. The hours of maxima and minima correspond with those used in the registers of the Journal, and suggest the expediency of an alteration in those fixed for Observation by Sir JOHN Hanson EL, (see page 358.)
