30 PUBLICATION OF THE 'ORIGIN OF SPECIES.' [1859. 



cannot possibly do head-work, and I must make only actually 

 necessary corrections. But I will, as far as I can without 

 my manuscript, take advantage of your suggestions : I must 

 not attempt much. Will you send me one line to say whether 

 I must strike out about the secondary whale,* it goes to my

 will do good to the English sale. If it depended on me, I

 and only beg that she [Mme. Belloc] would get some scien-

 that, though I am a very poor French scholar, I could detect 

 any scientific mistake, and would read over the French 

 proofs." 



The proposed translation was not made, and a second 

 plan fell through in the following year. He wrote to M. de 

 Quatrefages : " The gentleman who wished to translate my
