The Technologist
An 1861 technology periodical published in London by Kent & Co., illustrated with engraved line drawings of mechanical and manufactured objects for an educated general readership. The four plates shown are numbered cross-sections and a split seed or fruit, a lumpy irregular solid, a smooth carved bowl-like object with a fluted rim, and a suspended curved frame with a rod and twisted cords. A designer could take from them the cross-hatched shading that models solid volume and the clean outline style of nineteenth-century scientific instruction.
