Postscript to the Paper on the Geology of Zante, by H. E. Strickland, Esq. 



Since the printing of the paper on the Geology of Zante, I have been 

 favoured by Dr. Daubeny with the following analysis of the mineral spring 

 described at p. 407: 



Specific gravity, r020. 



Solid contents in one pint, 174 grains. 



Ferrocyanite of potash produced no effect, proving the absence of iron. 



Barytic salts produced a cloud, proving the presence of sulphuric acid. 



Nitrate of silver produced a dense cloud, proving much common salt. 



Oxalate of ammonia produced a cloud, proving presence of lime. 



Phosphoric test caused evident indications of magnesia. 



From the above analysis it appears that the water of this spring differs but 

 little from ordinary sea-water. Indeed, from the manner in which it rises in 

 the sea, a large quantity of sea-water must unavoidably become mixed with 

 it. At the same time, its inferior specific gravity, its milky colour, the floc- 

 culi of Glairine, and the strong smell of sulphuretted hydrogen, all serve to 

 characterize it as a mineral spring analogous to those of volcanic regions.
