the struggle £or existence, adaptations, sexual selection, and 

 results o£ selection. In the arrangement of his specitnens, in 

 order to bring out the various ideas, Professor Herrera places 

 them in series and places them in c®ntrast, using either method 

 as seems most suitable to each occasion. 



The paper is undoubtedly suggestive, and it is not intended 

 to be anythingmore; no doubt Professor Herrera would agree 

 that each curator must find his ideas and work them out for 

 himself, in aecordance with the circumstances of the museum 

 in which he is placed. Neither does he mean to deny that so- 

 me such arrangement of the museum according to ideas has 

 found its scattered instances; indeed, he does allude to some 

 of those beautiful cases that adorn the entrance-hall of the 

 Natural History Museum in London, exemplifying such biolo- 

 gical ideas as variatiou, protective mimiery, and albinism. But 

 it is still true that the idea which governs our museums is the 

 arrangement in aecordance with some human system of classi- 

 fication— "Why !" says our author, "the decimal classification 

 that is being adopted for librarles is preferable to the natural 

 (?) classification. It is this that will be universally applied in 

 the museums of the future." And thus he concludes : "All I 

 know is that i£, fifty years ago, museums had adopted the phi- 

 losophical and not the systematic order, then man, seeing side 

 by side the animáis of the deserts, would have discovered pro- 

 tective mimicry fifty years ago. ISeeing together on one side 

 the victims, on the other side the executioners, and further o'ff

man has tried to imprison the things of nature in a fixed sys- 

 tem, a fixed classification, which is not the whole of science, 

 and which cannot be the nest of all philusophy. Nature, in her 

 vastness, protests againstthe chassifiers; maddneed,indignant, 

 desperate she revolts against routine. A Darwin and a Huxley 

 as yet have lived in vain ; for we, here below, we classify, cla-
