M. De La Roche and Berard be correct, that other causes, besides density and capacity for heat, interfere with the phenomena. Thus nitrous oxide, which is nearly one-third denser than oxygene, and which, according to De La Roche and Berard, has a greater capacity for heat in the ratio of 1.3503 to.9765 in volume, has lower powers of preventing explosion; and hydrogene, which is 15 times lighter than oxygene, and which in equal volumes has a smaller capacity of heat, certainly has a higher power of preventing explosion; and defiant gas exceeds all other gaseous substances in a much higher ratio than could have been expected from its density and capacity. The defiant gas I used was recently made, and might have contained some vapour of ether, and the nitrous oxide was mixed with some azote, but these slight causes could not have interfered with the results to any considerable extent. Mr. Leslie, in his elaborate and...
