The residue furnished by distillation much vegetable oil and some 

 ammonia. Muriatic acid dissolved from the product some phosphate 

 of lime, but water with a little potash dissolved it completely, pro- 

 ducing a thick mucilaginous liquid in which acids formed a coagulum. 

 The mucus matter taken up by the boiling,water was yellow and 

 semi-transparent. Nitrate of lead and sulpnate of iron, nitrate of 

 copper, lime water, barytes water, formed gelatinous precipitates 

 with it. Tannin rendered it opaline. Iodine had no effect. All 

 these properties are exactly similar to thosp which have been recog- 

 nised as characteristic of the mucilage of the Nostoc commune a 

 species of Alga common in this country. From which it appears, 

 that this plant holds an intermediate place between animals and 

 vegetables. The volvox then consists of, 



1. A peculiar matter forming the greater portion of the animal. 

 2. Chlorophylle. 3. Mucilage identical with that of Nostoc com- 

 mune. Animal matter soluble in alcohol. 5. Chloride of potassium. 

 6. Phosphate of lime. 7« A combustible acid united to potash. 



XII. — Capnomore, 



Capnomore has been so termed by Reichenbach, because it is met 

 with in the smoke of organic bodies decomposed by fire. When pure 

 it is a transparent colourless liquid, possessing the smell of rum or 

 punch with a very agreeable taste. Specific gravity 0*9775 at 68 F. 

 It boils at ^Q^"" under a pressure of 28*25 inches. It does not con- 

 geal at — 5*8°. It evaporates without leaving any residue, it is a 

 non-conductor of electricity. , With the vegetable bases it acts as an 

 acid, and with sulphuric acid and the salts as a base. It does not 

 appear to unite with other bases, for a combination seems to be 

 produced ; it is decomposed by water. Capnomore is distinguished 

 from creosote and picamare by its taste, its insolubility in the 

 alkalies and acetic acid, and by the facility with which it dissolves 

 elastic gum. It differs from eupion by its specific gravity, and 

 boiling point, by the soot which it produces when burning, by its 

 solubility in sulphuric acid, its decomposition by nitric acid, and its 

 solubility in carbazotic acid, and the vegetable bases. (Journ.de 

 Chim. Medic, i. 195). 



XIII. — Iron works in the Uralian District. 



In this district there are nine iron works, of which, the oldest, 

 Nischney Taguilsk, was built in the year 1702, by Demidowitsch 

 Demidoff. It was so improved by Nicholas Demidoff that it pro- 

 duced annually five millions of roubles (of 833,333 6s. 8d.) Iron 

 and copper are smelted, gold and platinum are washed, and lead full 

 of silver and diamonds are obtained. The gold brings about 

 1,800,000 paper roubles, the platinum 1,152,000 roubles. After 

 paying expenses, the product of the iron, gold, and platinum, 

 amounts to from 2,600,000 to 3,000,000 roubles (£433,333 or 

 £500,000). 



To the north of Taguilsk lies the iron work of Kuschva, on the 

 mountain Blagodat. The vein consists of magnetic iron ore. —
