...the former gases was more opposed by mechanical causes. It is evident that the diffusiveness of .the gases is inversely as some function of their density — apparently the square root of their density. •- The results, however, are much influenced by the mechanical resistance arising from gravity, which...

...of the two former was more opposed by mechanical means. It is evident that the diffusiveness of the gases is inversely as some function of their density, —apparently the square root of their density. The effect of the position of the receiver was shown by an experiment on hydrogen gas. Other circumstances...

...Journal of Science, 1829, pp. 74-83, contains his first paper on the diffusion of gases. In it he states that the diffusiveness of gases is inversely as some function of their density, apparently the square-root of the density; he also considers it conceivable that orifices of excessive minuteness...
