I repeated this operation a great number of times, varying the capacity of the bell, or t^e quantity of the ^ir, as well as the mode of in- troducing the vapour; rejecting all (hose re- sults which could be affected by any accidental circuinsta^ce, and particularly by the smallest perpcptible quantity of red vapour. 87. I should have been astonished, if a dis- tillation, the essential property of which is not to decompose a single particle of acid, had furnished a sensible quantity of oxygen gas. But I still less expected to find, in opposition to the assertion of Mr. Keir, that instead of being meliorated by an additional portion of OX) gen, the air was actually deprived of a part of that pruiciple it possessed before the commencement of this process, which was, however, uniformly th^ case. Having allowed a sufficient time for the cooling and condensation of the vapours, the air in the bell was submitted to several eu- diometrical experiments, by nitrous gas, sul- phuret of pot-ash, and phosphorus; the mean difference, between the air introduced into the apparatus, and that which remained after dis-^ tillation,
