Rh Exp. C. a. and B. c. the lime has been shewn to be in combination with sulphuric acid: 5.68 grains of oxalate of lime, according to Dr. Henry, are equal to 7.1 grs. of sulphate of lime, both salts being dried at 160°: there are therefore 2.37 grs. of sulphate of lime in one ounce of the brine.

3. From the several experiments made with the view of determining the amount and nature of the sulphates, it has been inferred that there are 4.47 grs. of sulphuric acid in combination with soda in three ounces of the brine, which, (according to the proportions of Kirwan of 25.52 acid, 18.48 soda, and 58 water,) are equal to 7.98 grs. of dry sulphate of soda, or 2.66 in one ounce.

4. By Exp. B. it has been shewn that there are 0.32 gr. of muriate of magnesia in three ounces of the brine or 0.11 in one ounce.

Therefore the several salts contained in the ounce of the brine consist of
