Were I to say that I could not agree to accept such an arrangement • 

 of exosteate animals as this, I should simply announce that Mr. Dallas 

 and I differ in our views of system, and of course the announcement 

 of that difference neither depreciates Mr. Dallas's nor enhances the 

 value of my own ; but this I may say, that supposing Mr. Dallas to be 

 correct in his views, — supposing him to be philosophical in making 

 such novel combinations and in introducing such uncouth names, — 

 of this I am confident, that no "incipient" can master a system so 

 fraught with difficulty, and that Entomology must remain, for fifty 

 years at least, a sealed book to all but those who are deeply read, — 

 profoundly instructed in the speculative philosophy of the German 

 visionaries. 



Reviewing the system carefully, I find some points of accordance 

 with my own published views ; such is the reunion of the helmin- 

 thoids ; such is the juxtaposition of the Hemiptera, Orthoptera and 

 Neuroptera, of the Diptera and Lepidoptera, of the Hymenoptera and 

 Coleoptera. I am therefore in no way prejudiced against, but rather 

 in favour of, the principles Mr. Dallas has avowed ; but it seems to 

 me that he has committed two capital errors : he has carried into the 

 actiniate province laws which obtain only in the exosteate, and 

 in methodizing his views he has rendered them cumbrous and difficult 

 to understand. 



The work is full of illustrations, some of which are good, others 

 very bad : in the coloured frontispiece the ostriches have scarlet
