The methods given in this paper are as complete as we know how to make them. Many of the points are explained more fully in the references cited, and so these references must be used by the reader who wishes to follow closely as he goes through the present paper. A list of the symbols used is given at the end of this article. We propose to justify by a slightly different approach some of our megalithic astronomical results, and will consider two of the larger sites, Brogar and Temple Wood. The…

In a previous issue of this journal we showed! that the Megalithic site at Brogar almost certainly contains the remains of an important lunar observatory. We gave particulars of the probable
Observation of the Moon in Megalithic Times
To reduce any lunar observation at standstills we require the data given in Table 1. Then, with the declination previously calculated for the site, enter Table 2 and determine the nominal declination
