THE HISTORY OF ANATOMICAL SCIENCE 307 



thus accumulated was eventually summed up and 

 published, first in the lectures on the Inverte- 

 brates (1843) and, secondly, in those on the 

 Vertebrates (1 860-1 868). 



As methodically arranged and comprehensive 

 repertories of the anatomy of animals, it may be 

 a question whether these works are equal to 

 the contemporary ' Handbuch ' of Siebold and 

 Stannius ; but it may quite safely be said of 

 them, that they are based on the results of a 

 greater amount of personal investigation than 

 any work of the kind except, perhaps, Cuvier's 

 ■ Lecons ; ' and I put the exception doubtfully, 

 inasmuch as Cuvier was aided by highly skilled 

 assistants. 



Further, I think that Owen's monographic 

 work .occupies a unique position, if one con- 

 siders, not merely its general high standard of 

 excellence, but the way in which so many of 

 these memoirs have opened up new regions of 

 investigation. I mention the following, as some 

 of the most important from this point of view, in 

 addition to that on the Pearly Nautilus, to which I 

 have already referred. 



To begin with the higher animals, Owen's 

 early memoirs on the anatomy of the anthropoid 

 Apes contained by far the most complete and 

 adequate account of their structure, and of the re- 

 semblances and differences between them and man, 



then extant ; and they formed the foundation of
