Transcriber's Notes Obvious typographical errors have been silently corrected. Variations in hyphenation and accents have been standardised but all other spelling and punctuation remains unchanged. Several tables have been rearranged to improve clarity and constrain width. In particular the table of star signs on p 401 was printed horizontally with vertical names and has been rotated. The reference to 'the upper list' has been changed to 'the left hand list'. The names Shesu-Hor and Hor-shesu are used, apparently, interchangeably and have not been rationalised. The first two errata have been implemented, the third is erroneous. Italics are represented thus _italic_, bold thus =bold= and superscripts thus y^{en}.

The enormous advance which has been recently made in our astronomical knowledge, and in our power of investigating the various bodies which people space, is to a very great extent due to the introduction of methods of work and ideas from other branches of science.
