Abstract
THE year 1893 should be an interesting one to nautical men. A new Daniel has come to judgment in the person of Mr. Ernest Wentworth Buller, M.R.A.I., M.R.U.S.I., M.I.E.E., the inventor of the semi-azimuth system of navigation, who is equally earnest in denouncing the shortcomings of the existing systems of navigation, and in advocating the merits of his own. For the precise object of the new method let our author speak for himself. In page iv. of the preface we read: βIt is here claimed for the semi-azimuth method that it renders double altitudes unnecessary; that a better result than they have been supposed to yield can be obtained from either observation singly, and this also with a great saving of time and trouble.β
