He observed that it combined directly with certain metals without effervescence and that it formed an explosive compound with ammonia. Although these striking properties made him suspect the presence of a new element, he was too lacking in self-confidence to attempt a thorough investigation in his poorly equipped laboratory and too poor to take the time from his business (11). He therefore asked two of his Dijon friends, Charles-Bemard Desormes and Nicolas Clement, Desormes future son-...
