candlesticks without oil, invented, I believe, by Woolaston. A 

 metal stem passes down into the liquid, and, once heated, is afterwards 

 kept warm by the burning 1 vapour, which it causes to rise and 

 issue from the gas-jets encircling the stem. Some mystery is made 

 about the liquid, but its analvsis proves to be very simple. 



Specific gravity, "760 at 32°; easily volatile, with a smell of turpen- 

 tine. 100 grs. allowed to evaporate spontaneously, left barely a trace 

 of solid matter — resinous. 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 for the Spleen. 

 The late Dr. Twining 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 Jenkins is anxious for the result of their examination ; 

 but I really am uncertain of two, which arrived in a dirty and odo- 

 rous state — one, No. 3, containingan 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 Macleod favoured me with a bottle of water from the 

 lake near the Khyendwen river, whence a mineral salt is obtained. It 

 had a 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 - 0006 at 88°, and yielded a copious precipitate to muri- 

 ate of barytes, and nitrate of silver, shewing it to contain a mixture 

 of sulphates and muriates, which are extracted by the people of the 

 neighbourhood. 



8. — Hot Springs in the Mahadeo hills, (see Vol. III. p. 390. ) 

 The two bottles sent me bv Dr. Spilsbury were so nearly pure, that it 

 was not worth while to examine them further than by the hydrometer. 

 9. — Minerals from Moulmien. 

 The following are, I believe, the correct names of the specimens 

 obligingly sent by Lieut. Foley, in June. Nos. 1, 4, 16, irom pyrites ; 

 2, galena ; 3, sulphuret of antimony ; 8, 9, hydrated oxide of iron, hse- 

 matitic; 10, fibrous gypsum ; 11, magnetic oxide of iron; 12, 14, 17, 

 granite with pseudo- metallic mica ;13, black oxide of tin.
