of similar relics to those he now produced. He then went 

 on to show that the specimens he produced, when tested by 

 various experiments, were found to correspond with Mr. 

 Beetz's experiments, so far as he (Mr. Lucas) had had the 

 opportunity to carry them. Two of the pieces were found 

 in an old mine near Eyam, where they were believed to 

 have been from 40 to 50 years. Another piece, however, 

 was changed almost completely to the appearance of chalk, 

 and it was found in a mine where it must have been for 

 150 years. All appearance of a wick had disappeared in 

 the latter piece. Remnants of candles from the wreck of 

 the Royal George had a mineralised appearance, and had 

 no remains of wick. Mr. Lucas concluded by explaining 

 the theory of the change, which he compared to the discovery 

 of dead bodies found in the state of adiposea. 



Mr. BiRAM confirmed the statement as to the similarity 

 of those fragments to a portion of candle from the wreck 

 of the Royal George, which was in his possession. 



The Chairman thought it probable that the wick in the 

 more completely changed portion was decayed. 



Mr. Morton was inclined to think that the vegetable 

 wick, if it were decayed, must have left a mark of carbon. 

 He proceeded to remark on the fact incidentally noticed 

 by Mr. Lucas, that butter made in summer contained the 

 greater proportion of oleine, and in winter of stearine. 

 This he traced, not to the change of atmosphere, but of 

 the food of the animals. He inferred, from the analysis 

 detailed by Mr. Lucas, that the stearine candles, in which 

 the oleine was removed, were very superior. 



Mr. Lucas, in reference to the feeding of cows, referred 

 to the statement of Professor Playfair, that the milk of 

 cows grazed out of doors contained casine, the principle of 

 cheese, but was not of equal advantage for butter. The 

 milk of cows fed in the house did not so well produce cheese.
