at the period assuming shape in his mind. They have done 

 more than all else of their period to rationalise the application 

 of our knowledge of the Vertebrata, and have now left their 

 mark for all time on the history of progress, as embodied in our 

 classificatory systems. 



He was in 1882 extending his important observations upon 

 the respiratory apparatus from birds to reptiles, with results 

 which show him to have been keenly appreciative of the exist- 

 ence of fundamental points of similarity between the Avian and 

 Chelonian types — a field which has been more recently inde- 

 pendently opened up by Milani. 



Nor must it be imagined that after the publication of his 

 ideal work on the Crayfishes in 1880, he had forsaken the In- 

 vertebrata. On the contrary, during the late '70's, and on till 

 1882, he accumulated a considerable number of drawings (as 

 usual with brief notes), on the Mollusca. Some are rough, 

 others beautiful in every respect, and among the more conspicu- 

 ous outcomes of the work are some detailed observations on the 

 nervous system, and an attempt to formulate a new terminology 

 of orientation of the Acephalous Molluscan body. The period 

 embraces that of his research upon the Spirala of the Chal- 

 lenger expedition, since published ; and incidentally to this he 

 also accumulated a series of valuable drawings, with explana- 

 tory notes, of Cephalopod anatomy, which, as accurate records 

 of fact, are unsurpassed. 



As you are aware, he was practically the founder of the 

 Anthropological Institute. Here again, in the late '6o's and 

 early '70's, he was most clearly contemplating a far-reaching 

 inquiry into the physical anthropology of all races of man- 

 kind. There remain in testimony to this some 400 to 500 

 photographs (which I have had carefully arranged in order 

 and registered), most of them of the nude figure standing 

 erect, with the arm extended against a scale. A desultory 

 correspondence proves that in connection with these he was 

 in treaty with British residents and agents all over the world, 

 with the Admiralty and naval officers, and that all was being 

 done with a fixed idea in view. He was clearly contemplating 

 something exhaustive and definite which he never fulfilled, 

 and the method is now the more interesting from its being essen- 

 tially the same as that recently and independently adopted by 

 Mortillet. 



Beyond this, your father's notes reveal numerous other indi- 

 cations of matters and phases of activity, of great interest in
