My dear Sir,

I write to thankyou for your kind note. Especially am I gratified by your recognition of the heaviness of the labour which the writing of the book entailed.¹ Much the same, I am sure, is true of the reading, and I therefore beg that you will not waste your valuable time upon it— If however you will look at two “special Phylogenies” of mine which may be found at pages 138 and 152 of the Descriptions I should be glad. They are in the notes—²

What I say of the “problematical” character of such “special Phylogenies” at p. xxv. was prompted by the reading of Haeckel’s and of Semper’s speculations as to the Pedigrees of so many animals.³ Much of the entire mass of some of Haeckel’s writing, is made up of hypotheses of this kind; and as I am sure he is quite wrong in much of his speculation as to ancestry, I think other men may go equally astray wasting time and thought which might be spent otherwise more profitably.

May I ask you to put your pen on that same p. xxv through the words “the value of the” which come before the words “Special Phylogenies”. The sentence is now ungrammatical, having been made so in the correction of the proofs by the very (under other circumstances) proper substitution of the words “are likely to” for the words “must always”— The obliteration of the words “the value of the” will make the sentence decent which, as it stands, it is not.⁴

I am | Yours very Truly | George Rolleston
