| Notes | The cutting of objects into thin translucent section had been introduced for studies of wood in the 18th. Century, and in mid-19th. Century it was realized that soft tissues could be better studied if they were similarly supported for sectioning. Following Klebs' discovery, it was found that soaking dried tissues in molten wax allowed penetration of the tissue, providing both internal and external support for cutting purposes. A major advance. |
