that many valuable contributions on geographical subjects will be received from other individuals, whether on the List of Members or not, than those who are thus professionally qualified and invited to furnish them; particularly from such of their countrymen as have permanent residences abrouad, from the various public authorities in the British colonies, and from those who have travelled, or may yet travel, in foreign countries. It is not for the Committeen to specify in detail the various points of information which should engage the attention of the traveller; but they may observe that every species of information, connected either with Physical Geography or Statistics, if it have only accuracy to recommend it, will be acceptable; and in cases where the stock of information, generally, in the hands of any individual, is not of sufficient magnitude or importance to form a volume for publication, if sent to the Society, it will be made available, in some form or other, in its Transaction. The routes, for example, which travellers may have pursued through portions of countries hitherto but imperfectly known, or inaccurately described,—the objects of Natural History that may have presented themselves,—the meteorological and magnetic phenomena that may have been observed—the nature of the soil and its products, of its forests, rivers, plains, mountains, and other general features of its surface; but above all, the latitudes and longitudes of particular places which the Resident or Traveller may have had the means of determining to a degree of precision on which he may rely;—such notices of detached portions of the Earth's surface, where regular surveys cannot be held, are of extreme importance, as furnishing the only means by which anything approaching to correctness in our general Maps can be attained. And the Committee cannot, therefore, entertain a doubt, that it will constitute a part of the Transactions of the Society to publish such detached pieces of information bearing on each of these points, as may be thought of sufficient interest and importance to be communicated for the use of its Members, and of the public at large.
But there are many other means, besides those now mentioned, by which geography may be advanced, which are too numerous to be here specified at length. In addition to the few, however, which have been noticed here, as well as in the printed prospectus already circulated, the following points may be briefly stated, as being among the most important that will probably engage the attention of the Society:—
1. The composition of Maps illustrative of particular branches of geographical knowledge, more especially those relating to orology, hydrology, and geology.
2. The establishment of new divisions of the Earth's surface,
