Bitford, Alcester, Dioitwich, and Worcester. Mr. Strickland points out, also 

 for the first time, aline of fault ranging- from a little north of Bredon Hill, in 

 Gloucestershire, to Inkberrovv, north of the road from Alcester to Worcester. 

 By this fault the relative position of the red marl and the lias has been affected, 

 the former constituting- a valley of elevation, bounded on each side by the 

 latter. Mention is also made of bones and teeth of the hippopotamus, and of 

 a deer having been found in the gravel near Cropthorne, between Evesham 

 and Pershore. Mr. Strickland likewise alludes to the occurrence, on Shotover 

 Hill, near Oxford, of fossils which he believes to belong to the freshwater 

 genus Paludina ; but the specimens which he procured are imperfect casts. 

 These shells, he adds, were first discovered by the Rev. H. Jelly of Bath, in 

 a sand-pit on the brow of the hill, much higher than the pit in which the 

 Portland strata occur. 



3. — Notice of the Analysis of a Mineral fVater from the Island of St. Paul, 

 in lat. 38° 43' 8., and long. 11" 53' E. By John Bostock, M.D., F.G.S. 

 [Read January 7th, 1835.J 



The Island of St. Paul is stated, on the authority of Capt. Ford, who pro- 

 cured the mineral water, to be of volcanic origin, very rugged in its outline, 

 the highest part being about 700 feet above the level of the sea, and to have the 

 formof abowl 10 or 12 miles in circumference, into which thesea flows through 

 a narrow opening capable of admitting a boat. The surface of the island is, 

 in many places, covered with pumice ; and at night flames issued from various 

 crevices in the rocks. With the exception of the island of Amsterdam^ about 

 40 miles to the north, St. Paul's is at a great distance from any land. 



In the hole from which the water was taken the thermometer stood at 212°; 

 and there were numerous other springs, all of which were by the edge of the 

 sea. 



Dr. Bostock then explains the manner in which he conducted the analysis; 

 and afterwards compares the results with those obtained by Dr. Marcet from 

 water procured in the middle of the South Atlantic ; and infers from the 

 great difference in the mineral contents, that the water of the Island of St. 

 Paul is not merely the water of the neighbouring ocean in a state of dilution 

 or altered simply by mechanical filtration.
