11. Dr Dauheny'^s Circular requestiiig iiiformation in regard 

 to Mineral Waters. — For many years past we have urged the 

 importance of attention to the chemical and natural history of 

 liot-springs and mineral waters, and we are happy to find the sub- 

 ](xX taken up by one so well qualified to do it justice as our 

 friend Dr Daubeny. The following copy of the printed circii- 

 lar will explain Dr Daubeny\s wishes. 



" Sir, Being desirous of investigating the properties of such of our mineral 

 waters as appear as yet to be known but imperfectly, I take the liberty of so- 

 liciting information respecting those in your neighbourhood, and of submitting 

 to you for that purpose the following queries : — \st. Are you awai'e of any 

 springs in your country, or in those adjacent, the heat of which exceeds the 

 medium temperature of our climate ? 2d^ Is the temperature of such springs 

 fixed or variable ? 3rf, Do you know of any distinguished from ordinary wa- 

 ter by certain peculiarities, either sensible or chemical ? Ath, Are you ac- 

 quainted with any to which medical virtues are or have been ascribed, or 

 which, when taken, produce any remarkable effects on the animal functions ? 

 5/A, Do the springs above alluded to give out any gaseous products, and of 

 what description ? Gth^ What is the geological character of the stratum from 

 which they arise ? 'Jt\ What effects do they produce on the stones and other 

 substances with which they come in contact, upon the contiguous soil or upon 

 animals ? 8^A, Are there any works in which a detailed and authentic account 

 of such springs may be found ? In addition to answers to the above queries, 

 I beg leave to request any further information relative to hot or mineral wa- 

 ters which you may have it in your power to afford me ; and shall likewise 

 feel obliged by receiving samples of the more remarkable ones, carefully corked 

 and sealed on the spot, and in quantity not less than a pint. They may be 

 addressed to the Chemical Laboratory, Broad Street, Oxford, for Charles 

 Daubeny, Professor of Chemistry, Oxford." — Oxford^ l^th July 1827.

12. Rule to he followed in examining Caves co7itai7iing Fossil 

 Animal Remains. — Professor Buckland states, that the best rule 

 to follow in pursuit of antediluvian remains in caverns, is to se- 

 lect the lowest part in which any diluvium can have accumu- 

 lated, and there dig through the stalagmitic coat, and seek for 

 the teeth and bones in the mud and pebbles that lie below. He 

 also proposes, as a test for distinguishing bones of this antiquity,
