Burton's Navigational Publications, Alva Scotland. 1953. By the device of using versines instead of haversines in these tables it will be found that solutions of the astronomical triangle will be correct to within one minute of arc. Whether this degree of accuracy is satisfactory for navigational purposes at sea will doubtless long remain a matter of dispute, but it is certain that a considerable body of both British and foreign competent opinion considers that it is so. It may be advisable to mention here that the use of versines in place of haversines does not in any way affect the process of calculation. Indeed, were the fact not mentioned, the change would probably not be noticed by the majority of users. A further remark on this change occurs in the" Notes.
