I submit that I have correctly translated Mr. 

 Eomanes' meaning, and also that we have a right to 

 complain of his not saying what he has to say in 

 words which will involve less " ganglionic friction " on 

 the part of the reader. 



Another example may be found on p. 43 of Mr.

 Eomanes did not merely want to tell us all about 

 instinct, but wanted also, if I may use a homely
