Time Measurement: an Introduction to Means and Ways of Reckoning Physical and Civil Time

Abstract

IN this book the author has aimed at giving the rudiments of time measurement to readers possessing no previous knowledge of the subject. The first forty pages deal with the nature of time measurement and of the more prominent natural cycles (the year, the day) suitable for the purpose of measuring time. To assist the reader towards an exact understanding of the astronomical terms involved, the author insists upon the use of the globes and the armillary sphere, and describes in full detail a cheap home-made example of the latter instrument.
