EXTRACTS FOREIGN AND DOMESTIC. 145 



roil) the Russian Admiral commanding the squadron in the Eay of 

 lA-strabad ; he made one of his captains go and fill the bottle 

 far out in the Caspian Sea. An analysis of this water gave 

 n JOOO grams 13.2 grains of solid contents; of free carbonic 

 icid .24 equal to .5 of a cubic inch; and there is a large 

 |]uantity of sulphuretted hydrogen in it— .67 of a grain; and 

 his IS a much larger proportion than we generally find in sulphur 

 springs. The result .1 give thus :

This water contained no iodine and no bromine ; its taste is pe- 

 Liliar ; and it is a weak saline. 



, A bottle of Caspian water from close to the shore only £rave 

 I grains of solid matter in JOOO ; and nearly one of sulphuretted 

 ydrogen— a very large proportion of the laUer indeed, owino- to 

 le decomposition of the sulphates by organic matter. ^ 



I The analysis of the ocean water on the eastern coast of Africa 

 .so shows large quantities of sulphuretted hydrogen, produced by 

 lie decomposition of organic matter at the mouths of rivers on the 

 bast. This can be seen by reference to Prof. Daniel's analysis 



■ |nd this sulphuretted hydrogen, from this organic matter, is the 

 iiuse of the terrible fevers on the coast of Africa, where the mala- 

 a is said to prevail, and in all hot climates. ' 

 Prof. H. also said that Mr. Perkins had sent home a very curi- 

 is account of a salt pond in Persia, the water of which was five 

 etdeep, and the salt at the bottom five feet thick; the water 

 as separated from a large salt lake by a small sand bar; in hio-h 

 jinds the lake water was washed over the bar into the pond, and 



. jence was evaporated and salt made by the hand of nature. 



: je also sent home an account of a curious cave near Ooromania* 



: |t of which flows a stream of carbonic acid gas similar to that 

 ; the grotto Del Cano near Naples. 



: iDr. Booth said, that he formerly analyzed the Croton and 

 Jhuylkill waters ; the former had five grains of solids, and the 

 ifter four, to the gallon ; now, in the absence of disturbino- 

 Jiuses, the Croton only contained less than four grains to the gal- 

 lb, and M-as purer than the Schuylkill ; but the purest water he 



' <ler analyzed, was that of the creek at Washington city. The wate'-
