Chiefly devoted to an inquiry into the composition of the different 

 mineral springs of Bath. Grives analyses of waters from the Koman 

 Baths, King's Baths, Hetling Pump, and Cross Baths, which show that 

 the four springs which supply these Baths, though not artificially con- 

 nected, are derived from the same natural source. The waters of the 

 Hetling and Cross Baths are stronger in their mineral -constituents 

 than those of the two other Baths; allshow a daily variation, especially 

 in the amount of chlorine contained in them. The writer thinks it is 

 a question for consideration, whether the action of water, under high- 

 temperature and pressure, on carbonaceous residue, might not account 

 for the large quantity of carbonic acid gas given off by mineral springs, 

 or whether the internal heat of the earth may not 'have some decom- 

 posing action on the lower lying limestones. H. B. W.

 - This spring rises through an old mine-shaft, now covered up, and 

 passes by an underground passage to an opening -at the bottom of the 

 hill, discharging itself into the brook, at the rate of some 300 gallons 

 an hour. The writer gives an analysis of the water, comparing it with 

 that of the King's Bath. H. B. W.

 The boring is 1750 feet deep. The water contains chlorides.

Thinks that the salt water met with in the Coal Measures is due to 



old sea-water, and not to the minute amounts of salt which analysis 



reveals in the composition of Coal Measure rocks. In answer to a 



paper by M. Malherbe (see below). G. A. L.
