to the exclusion of the opposite view. Which conclusion is to be 
adopted, must be determined on other grounds; and from the 
various facts I have stated, I believe it may be regarded as the more 
probable opinion in such cases, that the original ingredients are sul= 
phate of soda and muriate of lime. Since sulphate of soda exists 
in the Bath water, and since muriate of soda and sulphate of lime 
are obtained in its analysis, it is scarcely possible to refuse assenting 
to the conclusion that these are formed by the action of sulphate of 
“soda on muriate of lime. 
On this view of the composition of the Bath water, it is easy to 
assiga the proportions of the ingredients, fom the products which 
are obtained in its analysis. In the formation of 3°3 grains of mu+ 
riate of soda, which is the quantity obtained from a pint of the 
water, 3°l grains of muriate of lime must be decomposed: four 
grains of sulphate of soda would be required to produce this de- 
composition ; and at the same time 3°8 grains of sulphate of lime 
would be formed. . 
The latest, and no doubt the most accurate, analysis of the Bath 
water, that by Mr. Phillips, gives the following view of its compos

The peculiarity in the composition of the Bath water, compared 
_ With the greater number of saline mineral waters, is that it contains 
a larger quantity of sulphate of soda than is necessary to convert its 
muriate of lime into sulphate of lime. Hence no muriate of lime 
is obtained after evaporation in its analysis ; hence even a portion of 
sulphate of soda is indicated; and hence the large proportion of 
sulphate of lime which that analysis yields. In the Dunblane and 
Pitcaithly waters the sulphate of soda’ is deficient, the muriate of 
lime is in large quantity, and is accompanied with muriate of soda: 
hence the entire want of sulphate of soda, the small quantity of
