PREFACE THE good friend who has so successfully ter- minated the task which he felt a vocation to undertake thought it would be of advantage to complete it by presenting to the reader a picture both of my life as a whole and of the work which it has been given me to accomplish. The better to accomplish his undertaking, he abstracted from my correspondence, as well as from the long conversations which we have so often enjoyed together, a great number of those memories of varying importance which serve as landmarks in life above all in a life like mine, not exempt from many cares, yet not very fruit- ful in incidents or great vicissitudes, since it has been passed very largely, in especial during the last thirty years, in the most absolute retire- ment and the completest silence. Moreover, it was not unimportant to warn the public against the errors, exaggerations, and legends which have collected about my person, and thus to set all things in their true light. In undertaking this task my devoted disciple has to some extent been able to replace those Memoirs which he suggested that I should write, and which only my bad health has prevented me from undertaking for I feel that henceforth I am done with wide horizons and far-reaching thoughts. And yet on reading now the old letters which he has exhumed from a mass of old yellow papers, and which he has presented and co- ordinated with so pious a care, that in the depths of my being it seems to me I can still feel rising in me all the fever of my early years, all the enthusiasm of long ago, and that I should still be no less ardent a worker were not the weakness of my eyes and the failure of my strength to-day an insurmountable obstacle. Thoroughly grasping the fact that one cannot write a biography without entering into the sphere of those ideas which alone make a life interesting, he has revived around me that world which I have so long contemplated, and sum- marized in a striking epitome,and as a strict inter- preter, my methods which are, as will be seen, within the reach of all, my ideas, and the whole body of my works and discoveries and despite the obvious difficulty which such an attempt would appear to present, he has succeeded most wonderfully in achieving the most lucid, com- plete, and vital exposition of these matters that I could possibly have wished.
