When all air was displaced, a weighed amount of the amalgam to be diluted was run into the empty half of C from a separating funnel filled with carbon dioxide. A Beckmann ther- mometer was then lowered into the hole, and clamped firmly in place, its bulb half way between the surface and the bottom of the amalgam. All the tubes leading into the calorimeter were also clamped, after which the tenth of a liter of a mixture of hard and soft paraffin melting at about 45 ° Centigrade were poured upon the ebonite cover. This, when hard, made the vessel F water-tight; but as an additional precaution a small outward pres- sure of carbon dioxide was always maintained by closing all outlets. The thermostat was now filled well above the top of F, and regulated by a very large and sensitive electric cut-off. The make and break was in an arti-.
