Abstract: After thirty years' labouring, the author accomplished to exchange the spheric trigonomical equation as follows: log 2(cos S+1)/2(cos S+cos Z)=log 2/1+cos H+log 2(cos S+1)/2(cos S+cos D) ∫Z0sin z/cos S+cos z・dx・log e=∫H0sin H/1+cos H・dx・log e+∫D0sin D/cos S+cos D・dx・log e It is confidently hoped that this table will be used to finish the nautical culculations within sufficient accuracy and the least time. Moreover, this new nautical table, conveniently, is well adapted for extending through the astronomical and the geometrical sailings, namely the calulation on the high altitude, the Ex-meridian altitude, the great circle sailing etc., at the same openning of a table.
