256 LIFE OF PROFESSOR HUXLEY CHAP. X 



The little book threatened to grow to an undue 

 length, and therefore the question of morals is treated 

 more briefly than was perhaps desirable. Ever yours 

 very faithfully, T. H. HUXLEY. 



Early in November I find the first reference to a 

 proposed, but never completed, "English Men of 

 Science" series in the letter to Mr. Morley above. 

 The following letters, especially those to Sir H. 

 Roscoe, with whom he was concerting the series, 

 give some idea of its scope : 



4 MARLBOROUGH PLACE, N.W. 

 Dee. 10, 1878. 



MY DEAR ROSCOE You will think that I have broken 

 out into letter-writing in a very unwonted fashion, but I 

 forgot half of what I had to say this morning. 



After a good deal of consultation with Macmillans, 

 who were anxious that the " English Men of Science " 

 series should not be too extensive, I have arranged the 

 books as follows : 



1. Roger Bacon. 



2. Harvey and the Physiologists of the 17th 



century. 



3. Robert Boyle and the Royal Society. 



4. Isaac Newton. 



5. Charles Darwin. 



6. English Physicists, Gilbert, Young, Faraday, 



Joule. 



7. English Chemists, Black, Priestley, Cavendish, 



Davy, Dalton. 



8. English Physiologists and Zoologists of the 18th 



century, Hunter, etc. 



9. English Botanists, Ray, Crew, Hales, Brown. 

 10. English Geologists, Button, Smith, Lyell.
