various efforts converge. In the meanwhile it is a very 

 precious encouragement to me to be approved and praised by a 

 man such as you. Your works have given you a great name, 

 and have placed you in the first rank among experimentalists 

 of our time. The admiration which you profess for me is in- 

 deed reciprocated ; and we must have been born to understand 

 each other, for true science inspires us both with the same 

 passion and the same sentiments. 



' ' Forgive me for not having answered your first letter ; but 

 I was really not equal to writing the notice you wanted. I 

 have deeply felt for you in your family sorrow; I have been 

 through the same trial, and I can well understand the suffer-

Henri Sainte Claire Deville, who was as warm-hearted as 

 he was witty, had, on his side, the ingenious idea of editing 

 an address of collective wishes for Claude Bernard, who 

 answered : "My dear friend, You are evidently as clever in 

 inventing friendly surprises as in making great scientific dis- 

 coveries. It was indeed a most charming idea, and one for

 way to it. 



' ' I have received the article Pasteur has written about me in 

 the Moniteur ; that article paralysed the vasomotor nerves of 

 my sympathetic system, and caused me to blush to the roots of 

 my hair. I was so amazed that I don't know what I wrote to 

 Pasteur ; but I did not dare say to him that he had wrongly 

 exaggerated my merits. I know he believes $]] fihp* ^"^ nrrifnn-, 

 and I am happy and proucfoT his opinion, because it is that of a 

 scientist and experimentalist of the very first rank. Neverthe- 

 less, I cannot help thinking that he has seen me through 

 the prism of his kindly heart, and that I do not deserve such 

 excessive praise. I am more than thankful for all the marks 

 of esteem and friendship which are showered upon me. They 

 make me cling closer to life, and feel that I should be very
