the water should be just bearable by the hand. It is then to be 

 poured upon the corn, placed in a tub, stirring it continually, 

 at first with a stick, and then with a shovel. The fluid should, 

 at first, cover the wheat three or four fingers' breadth, but it 

 will soon be absorbed by the grain. It should remain in this 

 state twenty-four hours, being turned over five or six times in 

 the interval. Whatever fluid will drain ofl" is then to be sepa- 

 rated, and the seed, after standing a few hours, so that it may 

 run freely out of the hand, may be sown. Jf not to be used 

 immediately, it should be put in a heap, and moved once or 

 twice a day till dry. 



This grain germinates sooner than unlimed grain, it germi- 

 nates with more certainty, and insects will not attack it.

Mr. Editor, — Sir, 



During my late tour into Derbyshire, 1 was pleased at 

 meeting with compact fiuor, which has not before been no- 

 ticed, to my knowledge, in that county ; it occurs sometimes 

 covered with beautiful cubic crystals of opalescent yellow fluor. 

 Another variety has frequently been called kevel. 



In a level driving from Castleton-town, in a west direction, 

 to the Odin mine, and, in the stratum called shale, several 

 small calcareous veins were cut ; from one of them some fine 

 crystallizations were obtained of the primitive rhomb, and from 

 another, rushed a current of air of small magnitude, which 

 inflamed when a lighted candle was applied to it. In one in- 

 stance it burnt all night, but it was exhausted in a few days. 

 Some years ago, perhaps thirty, I have heard of the miners 

 selling specimens of green selenite ; they occurred in the Odin 

 mine : latterly, some very fine phosphates of iron have beeo 

 met with in that neighbourhood : it is doubtful if what were 

 called green selenite were not phosphates of iron. In the shale, 

 this substance is common, appearing as a blue pmvdcr, but it is
