" to the sea. The rock there, is a sort of decomposed iron-stone 

 *' under the form of balls. The sound compact iron-stone, having 

 " the appearance of flat pebbles worn by the rolling of the sea, occurs 

 " not unfrequently along the shore." 



§ II. General Qiialkier and specific Gravity of the l^^ater, 



' a. The water issues from the sand rock above described, perfectly- 

 transparent, and it continues so for any length of time, provided it 

 be collected immediately, and preserved in perfectly closed vessels ; 

 but if allowed to remain in contact with the air, or even if corked up 

 after a temporary exposure to it, reddish flakes are soon deposited, 

 which partly subside, and partly adhere to the inside of the vessel. 



h. It has no smell, except that which is common to all chaly- 

 beates, and this it possesses but in a very slight degree. 



c. Its taste is intensely chalybeate, and, besides a considerable 

 degree of astringency and harshness, it has the peculiar kind of sweet- 

 ness which sulphat of iron and sulphat of alumine are known to 



d. Its specific gravity somewhat varies in different specimens. In 

 three different trials I obtained the following results : 

 1st specimen 1008,3 

 2d specimen 1007,2 

 3d specimen 1006,9 



3022,4 

 which gives a mean specific 



gravity of 1007,5
