with the little or no subsequent improvement, being an appa- 

 rent difficulty, it has just occurred to me that in fact the case 

 harmonises perfectly with our views. The case would be a 

 decided difficulty on the Lamarckian or Vestigian doctrine

Pray do not suppose that I expect to convert or pervert 

 you ; if I could stagger you in ever so slight a degree I 

 should be satisfied ; nor fear to annoy me by severe criticisms, 

 for I have had some hearty kicks from some of my best
