Characters as Adaptive and Specific. 173 



attention which, apart from any such antecedent 

 persuasion, they deserve. For example, a few years 

 ago I incidentally stated in a paper before the 

 Linnaean Society, that " a large proportional number 

 of specific characters " are of a trivial and apparently

 expressly given utterance to the same opinion. 

 When these statements were made, I did not antici-

 except perhaps, by Mr. Wallace. And, in order now 

 to show that my innocence at that time was not 

 due to ignorance of contemporary thought on such 

 matters, a sentence may here be quoted from a 

 paper which was read at the meeting of the 

 British Association of the same year, by a highly 

 competent systematic naturalist, Mr. Henry Seebohm, 

 and soon afterwards extensively republished. Criti- 

 cizing adversely my then recently published paper, 

 he said : 



" I fully admit the truth of this statement ; and I presume 

 that few naturalists would be prepared to deny that ' distinctions 

 of specific value frequently have reference to structures which 

 are without any utilitarian significance V " 



But since that time the course of Darwinian specu- 

 lation has been greatly influenced by the writings of 

 Weismann, who, among other respects in which he

 recently and extensively accused of ' heresy " to 

 Darwinian principles, for having stated that " a large
