He demonstrated that dry carbon and phosphorus will not inflame when heated in dry oxygen; that dry ammonia and hydrogen chloride when mixed do not unite, and that dry ammonium chloride and calomel respectively vaporise without dissociation.
Shown that dry hydrogen and oxygen mixed together are not ignited by exposure to the temperature of melting silver. These results are of the utmost importance in regard to the theory of chemical action.</OtherInfo>
