First printing (it was also issued the same year in Comptes Rendu) of Pierre Curie's famous doctoral dissertation in which he shows that when the temperature of a magnet is increased there is a level at which the magnetism is disrupted and ceases to exist, the temperature here is called the "Curie Point" and he further shows that Paramagnetism is inversely proportional to the absolute temperature, which is "Curie's Law".

"A little later Paul Langevin, who had been Curie's student at the 'Ecole de Physique et Chimie', proposed a theory that satisfied these facts (the facts expressed in the tqo laws) by postulating a thermal excitation of the atoms in the phenomena of magnetization.. Curie's experimental laws and a quantum mechanical version of Langevin's theory still constitute the basis of modern theories of magnetism."(DSB III, p. 506).
