NOTES

[1] _Horae Entomologicae_, by W. S. MacLeay, Esq. M.A. of Trinity College, Cambridge. London, 1819. A work which for acuteness of reasoning and profound research, has never been equalled either in this, or perhaps in any other country.

[2] It is truly grievous in those which are privileged to possess themselves of the works of their countrymen, however expensive, at free cost, and thus to inflict a ruinous fine on authors. Thus--National Institutions, founded for the encouragement of learning, are made to oppress and impoverish its followers.

[3] Were it necessary at this time of day to point out the unnatural separation of shells intimately connected with each other, which the Linnaean arrangement presents, it would be sufficient to observe, that the genus _Bulimus_ is formed of shells scattered in the old genera of _Turbo_, _Helix_, and _Bulla_: thus we see in Mr. Dillwyn's Catalogue, the large pink-mouthed African land-snail put in the same genus with our English _Bulla lignaria_, and _aperta_; the one inhabiting the depths of forests, and the others the depths of ocean!
