Cause, The Nebular Hypothesis, Illogical Geology, Tran- 

 scendental Physiology, Bam on the Emotions and the Will, 

 The Social Organism, The Genesis of Science, Manners and 

 Fashion, The Origin and Function of Music; and that this 

 group of essays be republished under some such title as, . 

 How all Things Progress. 3. That if this succeeds, I then

 System of Philosophy would form a good prefix to such a 

 volume of essays; since the essays would be so many 

 illustrations of it.

 expected from one in his position. I will see whether I can 

 find any appropriate materials for such a sketch as you 

 propose, and, if so, will send them to you.

 Derby I mentioned the measures I had recently been 

 taking to bring about an American reprint of your books. 

 We want them for general circulation. 



Sooner or later they will be republished. This will end 

 the sale of English copies, and if not attended to will cut 

 you off from any pecuniary advantage. Conscious of the
