INTRODUCTION. THE present volume, forming the second part of the Nautical Description of In the Introduction to the first part we have given a brief enumeration of the But there is one broad distinction, generally, in the geographical portion of One important part of Pacific hydrography is the relative value of the positions The work itself will give all the details respecting our present knowledge of This brings us to another point which has been alluded to in the previous volume, but for the sake of convenience we will repeat the substance of what is there stated, as the remarks are still more applicable to the tables which follow this, than to the longitudes of the points of the continental boundaries of the The latitude of a place is found with much greater accuracy and simplicity than its longitude, and therefore but little need be said on that point; but the But there is one mode, more especially insisted on by Lieutenant Raper, to whom so much is owing, by which it is almost in the power of any one possessing a good chronometer to verify or improve his predecessors' determinations. This is to connect any new or less known point with one better ascertained, whether the latter be absolutely correct or not. "The question would thus be narrowed into the determination of chronometric differences alone, until a favourable oppor- tunity occurred for the definitive determination of a fundamental position." Any improvement which is made in this primary point must, therefore, be extended to all those dependent on it. With this view Lieutenant Raper has selected twenty points in various parts of the globe, to serve as secondary meridians for the districts in their vicinity. Five of these refer to the Pacific. And as uniformity is in every way desirable, we have taken Lieutenant Raper's determinations as the groundwork; and, in addition to those he has chosen, several other points have been proposed in the first volume for the same purpose in the Pacific, and In the future determination of longitude by chronometer, it is hoped that the |
