1869 



IN 1869 Huxley published five paleontological papers, 

 chiefly upon the Dinosaurs (see letter above to 

 Haeckel, January 21, 1868). His physiological re- 

 searches upon the development of parts of the skull 

 are represented by a paper for the Zoological Society, 

 while the Introduction to the Classification of Animals 

 was a reprint this year of the substance of six lectures 

 in the first part of the lectures on Elementary Com-
