Maps of Solar Eclipses from 1850 to 1854

This eclipse map is unique among all the maps on this web site. The interesting feature on this map that is to be found in no other map are local corrections to angle of contact during the eclipse. From the map: “Correction to be applied to the Angles from Sun’s upper point at disappearance and reappearance on the central line of shadow, to give the angles from Sun’s upper point in other parts of the shadow.” Another interesting aspect of this map is that only a narrow strip of land is shown directly on or near the path of totality with the map tilted to follow the general path of eclipse. The full map is presented below.
