weeks would be requisite. It would be a grand haul for Letter 568 

 Palaeontology. I have been thinking over your lecture. 1 

 Will it not be possible to give enlarged drawings of some 

 leading forms of trees ? You will, of course, have a large 

 map, and George tells me that he saw at Sir H. James', at 

 Southampton, a map of the world on a new principle, as 

 seen from within, so that almost |ths of the globe was shown 

 at once on a large scale. Would it not be worth while to 

 borrow one of these from Sir H. James as a curiosity to 

 hang up ? 



Remember you are to come here before Nottingham. 1 

 have almost finished the last number of H. Spencer, and am 

 astonished at its prodigality of original thought. But the 

 reflection constantly recurred to me that each suggestion, to 

 be of real value to science, would require years of work. It 

 is also very unsatisfactory, the impossibility of conjecturing 

 where direct action of external circumstances begins and ends 

 as he candidly owns in discussing the production of woody 

 tissue in the trunks of trees on the one hand, and on the 

 other in spines and the shells of nuts. I shall like to hear 

 what you think of this number when we meet. 



To A. Gaudry. 2 Letter 569 



Down, Nov. 1 7th, 1868. 



On my return home after a short absence I found your 

 note of Nov. 9th, and your magnificent work on the fossil 

 animals of Attica. 3 I assure you that I feel very grateful 

 for your generosity, and for the honour which you have thus 

 conferred on me. I know well, from what I have already 

 read of extracts, that I shall find your work a perfect mine 

 of wealth. One long passage which Sir C. Lyell quotes from 

 you in the loth and last edition of the Principles of Geology 



1 A lecture on Insular Floras given at the British Association meeting 

 at Nottingham, August 27th, 1866, published in the Card. Chron., 1867.

 Museum, Paris, Foreign Member of the Royal Society of Lorydon, author 

 of Animaux Foss. et Geol dc rAttique.

 Gaudry's of this date in Mr. Darwin's library.
