In this new edition there are no references to photographic surveying air survey or photogrammetry. These are subjects that must either be omitted altogether or take up a considerable amount of space if treated adequately. There are now many excellent books devoted solely to these subjects. This edition is completely newly written-no text has been directly transferred from the fifth edition. Only the general arrangement has been followed as closely as possible. However the opportunity has been taken to attempt to get away from the somewhat stereotyped style of presentation that has developed over the years and is particularly noticeable in writings on field astronomy.
