About the Book

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ... the identification will be complete if the computation be but roughly made. The possibility that the observed body may be a planet must always be kept in mind in scanning the star table or chart. Example: At sea, February 26,1916, L. M. T. 6h 20m p. m. Weather overcast and cloudy. Observed the altitude of an unknown star through a break in the clouds to be 31 W (true), bearing 285 (true). STiat is the name of the star? Ship's position, by D. R., latitude 35 2C N., longitude 60 W. L 35 2V log sin 9. 762 log cos 9. 912 h 31 3(y log sin 9. 718 log cos 9.931 log cos' 9. 931 Z 285 00' log cos 9. 413 log sin 9. 985 A 0.302 log... 9.480 B 0.180 log... 9.256 A+B =0.302 + 0.180 = 0-482 = natsind.f = 2849/... log sec 10.057 t=H. A.=70=4h 40m log sin 9. 973 Then converting the hour angle into right ascension, as follows: L. M. T. 6h 20= R. A. M. S. 22 20 corr. for G. M. T. +2 R. A. 0 02 The right ascension and declination of the unknown star, as we have now approximately found them, are 0s OZ and 28 49/ N., respectively. The star is, therefore, a Andromedte, whose tabulated coordi"vites are right ascension 0 04m 02 and declination 28 37' 36'N. 394. Value Of The Moon In Observations.--Next to the sun, the most conspicuous body in the heavens is the moon, and it may therefore frequently be employed by the mariner with advantage. Owing to its nearness to the earth and the rapidity with which it changes right ascension and declination, the various corrections entailed render observations of this body somewhat longer to work out, with consequent increased chances of error; and errors in certain parts of the work will have more serious results than with other bodies; the navigator will therefore usually pass the moon by if a choice of celestial...
