any one in the way of knowing what it lauds." He strives to 

 effect it (and we think, with success) by discursive analyses 

 of the mode in, and extent to, which the human senses and 

 mind are ordinarily educated by the objects of nature ,* and by 

 indicating fresh paths, through which this worthiest object of 

 our being may be more intensely and extensively furthered.

conformity is the surest index of natural affinity : hence, ana- 

 tomical analyses of the structure of animals have become 

 essential to a knowledge of systematic zoology. The pre- 

 sent able memoir exhibits, in great detail both of description 

 and illustration, the anatomy of that most interesting animal, 

 the Nautilus Pompiiius L. ; and, in the process of doing so, 

 indicates the adaptableness of the structure discovered in the 

 animal to the functions required of it in its habits of life : 

 throughout the investigation, comparisons are made with the 



structure of other mollusques. The Memoir is a very inter-

 them), with explanations and illustrations of them. These, as 

 is known, are for the most part applied to the external organs 

 of insects ; but, in the present little book, the internal struc-

 imperfections in the book have been pointed out to us, and
