Abstract
FIFTY years ago or more, M. Beautemps Beaupré successfully employed a process which greatly facilitated the work of surveying, and which in its modern developments is likely to supersede the tedious work of measurement in the field. Where the greatest accuracy was not required, the method recommended itself on account of its great practical utility, enabling contoured maps to be produced without the labour of heavy calculations. M. Beaupré availed himself of the principle of the camera lucida, and by its aid sketched the panorama about him from two ends of a measured base line.
