[1878Q. Jrnl. Microsc. Sci. XVIII. 132 The lamellæ when stripped off from a bone that has been softened in acid but subsequently freed from all traces of the acid by long steeping in water or spirit exhibit under the microscope the appearance of intercrossing fibres (the reticulating fibres of Sharpey).] 1890G.
