Abstract
PROF. HOLT'S little book is intended for the instruction of those doing field work with theodolites. It contains a theoretical explanation of the heavenly motions sufficiently full to enable the student to follow the formulae with intelligence. The practical directions are clear and explicit. There is a useful table of formulae for solving spherical triangles, and some explanation of the solar attachments, which when used in conjunction with a theodolite enable the meridian to be found mechanically. There are tables at the end for the conversion of sidereal to mean time, refraction, azimuth of Polaris at elongation, etc. These tables indicate that the order of accuracy aimed at is the nearest second of arc. An error has been noticed on p. 82. In the equation just above (10) for cos z read cot z.
