Canada: In 1872 the South Kensington Museum in London UK commissioned Fabre de Lagrange of Paris to make 45 mathematical models for their Education Collection. The Canada Science and Technology Museums Corporation obtaind 28 of them from the Science Museum in 1973 through a deaccession. They still have seventeen models from the original commission.
Function: USED AS VISUAL AID FOR TEACHING DESCRIPTIVE GEOMETRY OF ENGINEERING.
Technical: In this model a skew quadrilateral has all its sides equal, and is pierced with holes at equal distances. It shows the plans and elevations of the right line generators. The rings show the parabolas of the principle sections. A brass stand made of 1/2" X 1/8" brass straps with cylinderical brass legs. The legs swivel at each corner. All brass frames have drilled holes. The flat square area is woven with green light green and light thread. This model will fold flat.
Area Notes: Unknown
