2. Postscript to the tnemoir on the Aust bone-bed, Tewkes- 

 bury, by Mr, Strickland. 



Since his former communication, the author has deter- 

 mined that the "bone-bed" has a further range north- 

 wards of at least ten miles, having ascertained that 

 it occurs in some old salt works on Delford Common, 

 in Worcestershire. The shaft of these works, 175 feet 

 deep, was emptied of its brine a few months ago, and it 

 was ascertained that it descends through the lias into 

 the gray marl, which forms the top of the triassic series, 

 but without reaching the red marl. The shaft, as the author 

 observes, consequently intersects the horizon of the bone 

 bed, and, among the rubbish thrown out, he found conside- 

 rable quantities of the peculiar white sandstone with bivalves, 

 which, in his former paper, he shows is the representative 

 of the bone-bed ; and he further noticed, that the sandstone 

 is occasionally charged with the teeth, scales, &c. which 

 are so numerous in the bone-bed at Coombe Hill. 



3. "0^ the high temperature of Well Water in the vicinity 

 of Delhi,'' by the Rev. R. Everest, 



If, says Mr. Everest, a line were drawn due west from the 

 Jumna at Delhi to the Indus, a distance of 100 miles, it 

 would intersect no river, brook or spring, water being ob- 

 tained only from wells. In Delhi, the depth at wliich 

 water is reached, is generally about 35 feet, 40 or 50 miles 

 to the westward from 80 to 90 feet, and beyond that dis- 

 tance, as far as Hausi, 95 miles, it is found at 150 feet. 

 The soil consists of a granitic alluvium, but the surface is 

 covered in many places with saline efflorescences, such as 

 the floods of Jumna now leave behind them. Mr. Everest 

 gives various tables of the temperature of well water, both at 

 Delhi and at points intermediate between that city and 

 Hausi ; but as the results, which vary considerably, are
