Abstract
BY the death of Troost, on September 30, at the ripe age of eighty-five, France loses the last surviving member of that group of workers—pupils of Henri Sainte-Claire Deville at the Ecole Normale —who created, mainly under his inspiration and leader ship, what was practically a new department of chemical science. Thermal chemistry, as we under stand it to-day, may be said to have originated in mid-Victorian times. It may be urged that the rela tions of chemistry to heat are so intimate that the study of these relations is necessarily as old as the study of chemistry itself. But it was only at the beginning of the latter half of the last century that the subject of thermal chemistry was attacked. Systematically, and for the most part in France, at the instigation of Deville, who, with the aid of Troost, Debray, Isambert, Hautefeuille, and Ditte, laid the foundations of that imposing superstructure to which this special department of knowledge has now attained.
