Having given you these tables of the Orders, from a comparison of which you will be able to trace the improvements in his system made by this learned Entomologist in the interval of eight years, I shall proceed to give those of his subordinate groups arranged under each. This I have already done, to save space, in the Arachnida and Insecta aptera.

If you examine the Orders as here given, you will find that they mostly represent natural primary groups of his Classes, though with regard to their distribution you may perhaps feel disposed to differ from him. You will also think that his secondary and minor groups[1433], with the exception of some of his sections, merit the same character. Indeed, he has left far behind all his predecessors in the progress that he has made towards extricating the true system. Setting out from a common centre he holds on his unwearied course, endeavouring to trace every set of objects that branches from it to its extreme term. But though he studied insects analytically with unrivalled success, he was not always equally happy in his synthetical arrangement of them. I do not here so much speak of the result which must necessarily follow from any arrangement in a series, and which cannot well be avoided; but I allude particularly to his intire adoption of the Geoffroyan system in the Coleoptera, which has prevented him in many instances from seeing the natural distribution of his groups.
