author of Die BefrucMung der Blumen (The Fertilisation 

 of Flowers), and of much other valuable work. 



The occasion of writing to Fritz Miiller was the latter's 

 book, Fur Darwin, which was afterwards translated by Mr. 

 Dallas at my father's suggestion, under the title Facts and 

 Arguments for Darwin. 



Shortly afterwards, in 1866, began his connection with 

 Professor Victor Carus, of Leipzig, who undertook the trans- 

 lation of the 4th edition of the Origin. From this time 

 forward Professor Carus continued to translate my father's 

 books into German. The conscientious care with which 

 this work was done was of material service, and I well re- 

 member the admiration (mingled with a tinge of vexation 

 at his own shortcomings) w r ith which my father used to re- 

 ceive the lists of oversights, &c, which Professor Carus dis- 

 covered in the course of translation. The connection was 

 not a mere business one, but was cemented by warm feelings 

 of regard on both sides. 



About this time, too, he came in contact with Professor 

 Ernst Haeckel, whose influence on German science has been 

 so powerful. 



The earliest letter which I have seen from mv father to 

 Professor Haeckel, was written in 1865, and from that time 

 forward they corresponded (though not, I think, with any 

 regularity) up to the end of my father's life. His friend- 

 ship with Haeckel was not merely the growth of corre- 

 spondence, as was the case with some others, for instance, 

 Fritz Miiller. Haeckel paid more than one visit to Down, 

 and these were thoroughly enjoyed by my father. The fol- 

 lowing letter will serve to show the strong feeling of regard 

 which he entertained for his correspondent a feeling which 

 I have often heard him emphatically express, and w T hich 

 was warmlv returned. The book referred to is Haeckel's 

 Generelle Morphologie, published in 1866, a copy of which 

 my father received from the author in January, 1867. 



Dr. E. Krause * has given a good account of Professor 

 Haeckel's services in the cause of Evolution. After speak- 

 ing of the lukewarm reception which the Origin met with 

 in Germany on its first publication, he goes on to describe 

 the first adherents of the new faith as more or less popular 

 writers, not especially likely to advance its acceptance with 

 the professorial or purely scientific world. And he claims
