These figures were obtained as follows:—Microphotographs were first obtained, and then, by a process recently acquired by Messrs W. & A. K. Johnston, a copperplate engraving is got, from which the figures were printed. The microphotographs were taken with a Hartnack's microscope and 2-inch object-glass. The increase in size is therefore about 12 diameters, and is a comparatively slight microscopic one.—Legend to Plate II.
The four photogravures were printed by the W. & A. K. Johnston firm, renown for its lithograph maps and globes. Original proprietors of the firm were William Johnston and his brother, Dr. Alexander Keith Johnston (1804-1871), who was geographer to the queen. A third brother, Thomas Brumby Johnston (1813-1897), took over the firm in 1871. He was a capable photographer and one of the founding members of the Photographic Society of Scotland in 1856.
