The second water was that of the Baths of Tiberias, at its source a sul- 

 phureous thermal, and of too high a temperature to permit of the hand 

 being held in it. It had not been previously analysed with care. Dr 

 Dalzell found its specific gravity at 60° to be 1022*5, and the solid residue 

 of a gallon to be 2821 grains, or about twice as much as Marah yields ; 

 nearly 80 per cent, of its saline matter was common salt, as the following 

 table showed :— 



Chloride of sodium .... 76*85 



Sulphate of lime . . . . . 11-01 



Sulphate of magnesia . . . . 12-14 



100*000 

 The third water was also sulphureous and thermal. Its original heat 

 must have been great, as, from some notes accompanying the bottles, it 

 appeared that a thermometer graduated to 120° Fahrenheit, instantly 

 burst on being immersed in it. At 60° he found its specific gravity to be 

 not far from that of the Marah well, viz., 1007*9, and the solid residue 

 from a gallon 1211 grains. Like the Dead Sea, it contained much, 

 magnesia, and, as in that water, so here, the amount of sulphate of lime 

 was smaller than in either of the preceding. Its analysis showed, of 



Chloride of sodium .... 73*215 



Sulphate of lime ..... 6*720 



Sulphate of magnesia . . . . 20065 



100*000 



Dr Dalzell concluded by stating, that in a portion of Dead Sea water 

 taken from the northern end,, the specific gravity of which was 12\0 at 

 60°, he found 17,402 grains per gallon of solid matter, 5612 of whieh 

 was chloride of magnesium, 29*62 chloride of sodium, 11 '25 chloride of 

 calcium, a little more that 2 per cent, chloride potassium, 0*43 sulphate 

 of lime, and 0*28 consisted of the bromides of magnesium and potassium. 



III. (1.) A few Fossils from Vancouver's Island were exhibited. (2.) 

 Notice of a Tetraodon (believed to be new) from Old Calabar. (The 

 specimens were exhibited.) By Andrew Murray, Esq. 



Mr Andrew Murray exhibited a few fossils from Vancouver's Island. 

 They belonged to the Lower Chalk, and consisted of a species of ammon- 

 ites and baculites (B. ovatus, Say,), Diceras (Caprotina, D'Orb.), Venus % 

 Unicardium, and Psammobica.
