Abstract
THE appearance of this volume brings us definitely face to face with a new situation in the derivation of accurate positions of the heavenly bodies from photographs. It will be remembered that in the winter of 1900-1 the recently discovered small planet Eros made a very near approach to the earth, and a large number of photographs were taken with the view of determining the distance of the planet, from a knowledge of which that of the sun, and the dimensions of the solar system generally, could be inferred with (it was hoped) considerably improved accuracy. The measurement of the plates involves enormous labour, and has only been partially accomplished in the intervening four years; and the discussion of the measures has necessarily proceeded even more slowly. But the present publication of more than 400 quarto pages represents a notable addition to the tabular statement of measures, and contains an important contribution to the discussion.
