The specific gravity referred to water at 15° C. was 1.0006. 



Eathbawx Chalybeate. 



The temperature of this water was found to be 13° C, when that 

 of the air was 15°.l C, being a difference of oidy 2°.l, whilst in the 

 case of the Gowlaun water, the difference was 4°. 5 : this may be ac- 

 counted for by the more open situation of this well, which is more 

 freely exposed to sunshine. This water contains, in addition to the 

 usually occurring substances, a ferrous salt, and also a weighable 

 quantity of manganese ; this latter substance does not appear to have 

 been before detected. The several constituents are : —
