Table of the quantity of vapour of ether in 100 cubic inches of air, saturated with it at various temperatures.--

At about 45° the weights of vapour of ether and of air are equal, and at a little above 70° the volumes are equal. The weights are calculated with the barometer at 30.

* * * From this it will be seen that the quantity of ether administered with air varies materially with the temperature.
