IT is hoped that the great variety of new, useful, curious and entertaining articles which will be found in the following work, will entitle it to a favourable reception from the public. No pains nor expence have been spared to give it as much accuracy and perfection as the nature of such a work will admit of. And though we do not flatter ourselves that it will be absolutely free from errors or imperfections, yet we doubt not but the candid reader will find so much to commend, that he will easily be inclined to excuse some unavoidable deficiencies. The Environs of London, though they contain many of the most remarkable seats and places in the kingdom, have never before been included in any account of that metropolis; and we are persuaded, that the most intelligent enquirer will here find numberless curiosities, not hitherto taken notice of by any other writers: besides, we have not only been particular in our descriptions of whatever is remarkable twenty miles round; but to assist his observation, we have added a map, which we flatter ourselves will be found to have some advantages over any other that has yet appeared. This map, and these descriptions, will serve both as a guide and an instructor to the travelling Virtuosi, whether natives or foreigners, in their little excursions to any part of these delightfully adorned and richly cultivated environs. In order to render the knowledge of this metropolis as complete as possible, we have necessarily been obliged, in conformity with our plan, to treat of what may to some appear little and uninteresting, as well as of what is great and important. Among these the citizens are particularly interested in knowing the extent and limits of the wards in which they reside: and it was absolutely necessary to mention in their proper places all the several companies that compose their whole body: and as every inhabitant of the kingdom may, at one time or another, have occasion to visit or write to their friends or relations residing in this great city, the names and situation of all the several streets, lanes, rows, courts, yards and allies could not be omitted. With regard to these an ingenious gentleman has furnished us with a key, which has let us into the origin of many of their names; and this part of our work is farther illustrated by a new and correct plan. The prints with which the whole is decorated, are all engraved by the best hands, after original drawings, which were taken on purpose for this work, from the several objects themselves, at a very great expence; and we imagine they will not only be considered as an ornament, but that they will be found of use in illustrating the verbal descriptions.
