Book excerpt: Excerpt from A Catalogue of Stars for Latitude Observations on Dominion Lands Surveys Just at this time a copy of Boss' Star Catalogue for was received. Now the results of large numbers of pairs of stars in zenith telescope observations had previously shown that those pairs of stars which had the largest residuals from the resulting mean latitudes were almost invariably pairs composed of either two Ambronn stars or one Ambronn and another star. For this reason the same confidence was not placed on Ambronn stars as on the stars of the other catalogues. When the positions of such stars as were given in both Ambronn and Boss were computed from both catalogues it was found that there were many stars which showed differences in declination as high as 5 and some even as much as 8 and over. It was decided therefore to revise the catalogue by giving the positions of such Ambronn stars as were in the Boss Catalogue from the latter catalogue. Mr. Waugh took this in hand, but was obliged to leave for the field before the re vision was completed. The work was then carried on by Messrs. W. H. Herbert.
