Jean-Félix Guyon (1864-1907) should not be confused with his father, the eminent urologist Jean-Félix-Casimir Guyon (1831-1920). And this book about the work of Jean-Félix Guyon should not be confused with "Notice sur les titres et travaux scientifiques" by Félix Guyon (that is, Jean-Félix-Casimir Guyon), published in 1877 and 1892. SIGNED BY JEAN FELIX CASIMIR GUYON TO JOSEPH JULES DEJERINE (on the second front flyleaf; see photo). Quoting from the Preface by D'Arsonval about his student and assistant Jean-Félix Guyon (in English translation): "During these thirteen years preceding his death, I was able to see him at work, to appreciate at the same time his ardor for research, his loyalty and his sincerity as an experimenter, all his qualities of heart and mind. This long intimacy created by the laboratory authorized me to think that I knew well everything he had done and that I was not a stranger to any of his scientific preoccupations. Reading these pages I had to admit that some points had escaped me and that the whole of my assistant's work formed a harmonious whole that I had seen much less clearly when going through his successive notes. All these works owe their incontestable value to the implementation of the moral qualities and the scientific spirit that characterized their author. I am all the more at ease in saying all the good things I think about the work of Jean-Félix Guyon because one cannot suspect the master of indirectly praising himself by glorifying his student. Jean-Félix Guyon, in fact, was my student by his functions only, but not by his work. His research relates to pure physiology and his incursions into biological physics, where I could have guided him, were few. His work therefore belongs to him in its own right and it is only sometimes that I had to indicate to him some detail of instrumental technique which could simplify his operating equipment. . . . I had persuaded my assistant to replace me in the chair of medicine during the year 1907-1908 to give him the opportunity to masterfully present his work. It had not been without difficulty, because his modesty feared, quite wrongly, to assume the burden of this official teaching. Death came to surprise him at the moment when he was writing the program of the lessons that he intended to keep silent. The presentation that we are about to read shows what the theme would have been; it can only give an incomplete idea of what this teaching would have been. However, the reader will judge, as I did, that it was worthy of the Collège de France.". Signed by Author(s).
