the sulphuretted hydrogen was very strong and marked. With so 



small a quantity, however, our analysis, as to quantity, is necessarily 



imperfect, neither can we pronounce on the presence or absence of 



Iodine and Bromine as above remarked. Mr. Hodgson will, I have no 



doubt, favour us with a larger supply, when these questions will be 



settled.

As the water in both bottles had decomposed, it was useless to 



examine it for the quantity of the gaseous contents. 

 Twenty-two ounces of the water, (of B) carefully evaporated and 



the residue examined, gave as follows

The water is thus a carbonated and sulphuretted chalybeate 



spring, containing its iron in the peculiar state in which it is found 



in the Bath waters. 



It also greatly resembles one of the Harrowgate springs. 



By the kindness of Mr. Grapel who brought down the water, I 



have been able to ascertain that the bottles must nave been filled
