Forty-eight ounces of this water being evaporated gave a slightly 

 coloured residuum and a considerable white crystalline sediment 

 weighing in the whole 11 grains.

The spring is thus a carbonated, calcareous and magnesian water, 

 with a slight, though probably efficacious proportion of iron ; which 

 is of course in the state of carbonate, and held in solution in the 

 water. 



III. 



Mineral Water from Sosoneah, North of Hazareelagh, from W. H. 



Elliott, JSsq. f O. S., through Mr. Geote. 



I had three small pint bottles of this water, but the whole were 

 very badly corked. 



Examined by the same tests as the foregoing, the carbonic and 

 muriatic acids only were found, and of the bases lime, iron and soda 

 were present ; but the whole are in very small quantity, the total 

 of the saline matter and sediment obtained by the evaporation of 

 24 oz. being 1.70 gr. ; so that we can only at present say, generally, 

 of this water that it is a carbonated and slightly chalybeate spring, 

 with a little muriate and carbonate of soda also in solution. Never- 

 theless when a larger quantity in proper preservation can be 

 obtained, it should be re-examined for Iodine and Bromine as above 

 remarked. I add to this paper, a circular from the Medical Board 

 with which I have been favoured by Dr. Macpherson, which give 

 excellent directions for collecting mineral waters for analysis, and a 

 list of many springs of which we know nothing and now that com-
