Abstract: The H.O. 214 and 218 methods in celestial navigation are being used increasingly because of the brevity of the procedure. However, for those who are willing to do a small amount of computing, the Dreisonstok (H.O. 208) and Ageton (H.O. 211) methods have been available in single inexpensive, pocketsized volumes. The former of these has been considerably less popular, judging by the amount of space devoted to it in most of the texts which have appeared during the war. This was probably due to the feeling, as stated to the writer by one experienced navigator, that “in the Dreisonstok method the computation is shorter, but the rules or precepts are harder to remember and harder to apply.” However, the announcement by S. Herrick [I] that the Ageton method is subject to errors, in some cases as large as 30’ (when used without interpolation as recommended), has led to rather widespread abandonment of that method. It is the purpose of the present article to suggest a change in the Dreisonstok rules which will remove the objection as stated above.
