In my previous paper I endeavoured to establish a basis for calculating the amount of fresh air necessary to keep an air-space sufficiently pure or health, taking the carbonic acid as the measure. The results showed that the mean amount of carbonic acid as respiratory impurity in air undistinguishable by the sense of smell from fresh external air was under 0·2000 per 1000 volumes . My object in the present note is to call attention to the relative effects of temperature and humidity upon the condition of air, as calculated from the same observations. If we adopt the figures of Class No. 1 (that is “fresh,” or not differing sensibly from the external air) we find the following:—
