DARWIN 141 



worked globule with centrifugal radiating needles, 

 embodied in the Heliosphcera. " At the same 

 time," he says, characteristically, " this does not 

 imply in the least that all the radiolaria must 

 have descended from this primitive form ; I merely 

 show that, as a matter of fact, all these very 

 varied forms may be derived from such a common 

 fundamental type." In other words, once more, 

 it is conceivable a golden word even long after- 

 wards. The first " genealogical tree," a " table of 

 the related families, sub-families, and genera of 

 the radiolaria," arranged in order from the higher 

 forms down, and connected with lines and brackets, 

 comes next. The text deals thoroughly with the 

 possibility of descent. This closes the first and 

 general part of the monograph. But there is a 

 long note at this point in the text, where Darwin's 

 title is cited, that gives us his first appreciation 

 of Darwin in detail. It begins : " I cannot refrain 

 from expressing here the great admiration with 

 which Darwin's able theory of the origin of species 

 has inspired me. Especially as this epoch-making 

 work has for the most part been unfavourably 

 received by our German professors of science, 

 and seems in some cases to have been entirely 

 misunderstood. Darwin himself desires his theory 

 to be submitted to every possible test, and ' looks 

 confidently to the young workers who will be 

 prepared to examine both sides of the question 

 impartially. Whoever leans to the view that 

 species are changeable will do a service to science 

 by a conscientious statement of his conviction ;
