Ryerson Physical Laboratory
Ryerson's laboratories were state of the art facilities for that time. The building was designed to optimize experimental conditions. To minimize vibrations from outside which could interfere with experiments, Ryerson was built with exceptionally solid construction. The building had an extra heavy foundation, heavy slate wall shelves and piers of masonry for the first floor laboratories. Basement laboratories were lined with thick cork to control the moisture level.
The first floor labs were devoted to research level works. Upper floors held student labs and classrooms as is shown in this floorplan of the third floor.
