1860.] AUSTRALIAN FLORA,

With respect to tropical plants during the Glacial period, 

 I throw in your teeth your own facts, at the base of the Hima- 

 la> a, on the possibility of the co-existence of at least forms of 

 the tropical and temperate regions. I can give a parallel case 

 for animals in Mexico. Oh ! my dearly beloved puny child, 

 how cruel men are to you ! I am very glad you approve of 

 the Geographical chapters. . . . 



C. Darwin to C. Lyell. 



Down [January 4th, 1860], 



MY DEAR L. Gardeners' Chronicle returned safe. Thanks 

 for . note. I am beyond measure glad that you get more and 

 more roused on the subject of species, for, as I have always 

 said, I am well convinced that your opinions and writings 

 will do far more to convince the world than mine. You will 

 make a grand discussion on man. You are very bold in this, 

 and I honour you. I have been, like you, quite surprised at 

 the want of originality in opposed arguments and in favour 

 too. Gwyn Jeffreys attacks me justly in his letter about 

 strictly littoral shells not being often embedded at least in 

 Tertiary deposits. I was in a muddle, for I was thinking of 



Secondary, yet Chthamalus applied to Tertiary 



Possibly you might like to see the enclosed note * from 

 Whewell, merely as showing that he is not horrified with us. 

 You can return it whenever you have occasion to write, so as 



not to waste your time.

* Dr. Whewell wrote (Jan. 2, 1860) :"...! cannot, yet at least, be- 

 come a convert, But there is so much of thought and of fact in what you 

 have written that it is not to be contradicted without careful selection of 

 the ground and manner of the dissent." Dr. Whewell dissented in a prac- 

 tical manner for some years, by refusing to allow a copy of the ' Origin of 

 Species ' to be placed in the Library of Trinity College.
