CHAPTER XXI 



1867 



It has already been noted that Huxley's ethnological 

 work continued this year with a second series of lectures 

 at the Royal Institution, while he enlarged his paper on 

 " Two widely contrasted forms of Human Crania," and 

 published it in the Journal of Anatomy. One paleontological 

 memoir of his appeared this year on Acanthopholis, a fossil 

 from the chalk marl, an additional piece of work for which

 belong to two species. But it is an awful business to compare 

 all the Ichthyosaurians. I think that one form is new. Please 

 to tell Nordenskiold this much. 



However, his chief interest was in the anatomy of birds, 

 at which he had been working for some time, and especially 

 the development of certain of the cranial bones as a basis 

 of classification. On April 11, expanding one of his Hun-

As he had found the works of Professor Cornay of help 

 in the preparation of this paper, he was careful to send him 

 a copy with an acknowledgment of his indebtedness, elicit-
