The tube and the wash bottle were immersed in a constant temperature bath. $\\ce{CO2}$ was bubbled through it rapidly for 30 minutes. The wash bottle was replaced by a mercury reservoir and the free gas was driven completely out of the saturating tube by admitting mercury underneath the solution. The $\\ce{CO2}$ contents of the solutions were determined in the manometric gas apparatus (Refs 1 and 2).", "reference": {"citation": "Van Slyke, D. D.; Sendroy Jr., J.; J. Biol.
