The purpose of these maps, like those of the total solar eclipses published earlier, is to enable a historian rapidly to identify an apparent reference in his sources to a solar eclipse, or to ascertain the moments at which eclipses might have been witnessed over specific areas in Africa. The originals have again been drawn to the scale of I: 10,000,000 by Mr A. K. Appleton, F.R.A.S., to calculations by Dr J. G. Porter, F.R.A.S., and represent precisely the same advance in accuracy compared with Oppolzer's charts. At the small scale at which these maps are here reproduced, however, it will generally be possible merely to arrive at approximate results; a more accurate assessment can be reached only by consulting copies of the originals, or, in some cases, by undertaking further calculations. Within these limits it is hoped that they will prove a useful indication of the possibilities of this type of evidence and will lead to the discovery of references that have not yet been published or reported
