Context

Country: Unknown
State/Province: Unknown
Period: Unknown
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: The model is intended to show the construction of the parabola connecting two roads which meet obliquely. The construction is used by engineers in laying out roads.
Area Notes: Unknown
