Excerpt from The Entomologist's Useful Compendium; Or an Introduction to the Knowledge of British Insects: Comprising the Best Means of Obtaining and Preserving Them, and a Description of the Apparatus Generally Used It must be acknowledged that the very rapid progress which every science for some years past has made in this country, is greatly to be attributed to Elementary works, and at the same time it is to be regretted that as yet none has appeared on the practical part of Entomology, by which I mean the method of collecting and preserving insects, the elements of the science, &c. It is true such a work is announced, and it is hoped will shortly appear; I allude to the completion of Messrs. Kirby and Spence's Introduction to Entomology. - From the profound knowledge of the subject which these excellent authors possess, we certainly may expect a most complete work; yet its extent, and the necessary expense of at least four octavo volumes, must exclude many from purchasing it, and especially young persons to whom the study of Entomology is particularly adapted. From this consideration I was induced more than twelve months ago to begin a work, the mere outline of the present, and which was intended to comprise little more than the Linnean Genera, with a slight notice of the more natural Genera which had been separated from them, with references to the best essays or papers that had been published on the subject, and directions for collecting, &c.
