Rare French reflecting circle of brass with inlaid silver scale divided from 0 to 180 degrees on either side of the zero point and signed "LORIEUX, LEPETIT suc Paris No 313" on the arc, with the additional mark "SH 140" on the index arm. The original dove-tailed fitted mahogany case with brass hardware also bears the brass tag reading "Service Hydrographique Cercel Hydrographique Lorieux Lepetit suc Paris No. 140." This instrument, with folding turned hardwood handle, was obviously used in the French Hydrographic Service for charting and mapping. (Private Collection. Ex. West Sea Co.)
