Abstract
THE introductory section of this volume1 contains an explanation of the symbols employed and of the sign conventions adopted, together with extensive tables of formulas designed to cover the trigonometrical calculation of rays through a series of centred refracting surfaces. The system described is probably far more extensively employed than any other by practical opticians. It is constructed throughout with a view to convenience in logarithmic computation, and only minor improvements have been effected since it was first published. Its popularity has not been seriously affected by the introduction of the calculating machine into the workshop.
