CUVIER CEITICISED 427 
What then, says the critic, of the sloth ? What structural 
distinction between herbivorous and carnivorous bears ? The 
principle, ' valuable enough in physiology, is utterly insuf- 
ficient as an instrument of morphological research.' Falconer 
attacked him in the June number. Huxley replied in July. 
[June ?], 1856. 
Dear Huxley, — I have been dissipating the disconsola- 
tion of my solitude (rather fine that) by reading old Quarter- 
lies as I nutrify and assimilate (better still) and find in xli. 
313 a passage that will amuse you and rile Falconer — ' Under 
the influence of this delusion " the necessary conditions of
