Deeply indebted as we are, in common with all who admire 

 the wonders of the creation, to that profound zoologist who has 

 succeeded more effectually than any of his predecessors in unra- 

 telling the intricacies of the system pursued by Nature in the 

 distribution of the animal kingdom, Mr. W. MacLeay has ad- 

 vanced still farther claims upon our gratitude in the excellent 

 and purely scientific work the title of which is quoted above. To 

 the more prominent features of the method which he has followed 

 it i$ unnecessary at this advanced perijod of our acquaintance with 

 it to advert particularly. Developed originally in that valuable 

 production, the '' Horaj Entomologicae," of which by far the 

 greater number of copies were unfortunately lost to the world, 

 these were further explained in a communication to the Linnean 

 Society, which has probably ere this passed through the hands of 

 nearly the whole of our readers. The outlines of the system 

 will therefore have become familiar to them, but they will have 

 remarked that the attention of the expounder of these luminous 

 views has hitherto been directed in general rather to the larger 

 and more striking groups than to the minor divisions of families 

 and genera. In the immense numerical extent of the insect tribes, 

 and in the evidently inadequate acquaintance with them which 

 we at present possess, sufficient reasons may at once be perceived 

 to show \\\e impossibility of immediately undertaking the stupen- 

 dous task of comparing together the whole of them, and of thus 

 elucidating throughout their respective affinities and analogies, 

 so as to establish a copnpletely natural system, at once perfect
