** "ITie other is, that the density of the gas In 

 the water has a special relation to that out of 

 the water, the distance of the particles within 

 being always some multiple of that without : — 

 Thus, in the case of carbonic acid, 8ic. the 

 distance within and witliout is the same, or 

 the gas within the water is of the same density 

 as without ; in olefiant eras the distance of the 

 particles in the'water Is twice that without; in 

 oxygenous gasj Zic. the distance is just three 

 times as great within as without ; * and in 

 azotic, &c. it is four times. This fact was the 

 riesult of my own enquiry. The former of 

 these, I think, decides the effect to be mecha- 

 nical; and the latter seems to point to the 

 principle on which the equilibrium is ad- 

 justed. 



Tlie facts noticed in the 4th, 5th and 6th 

 articles, were investigated h priori from the 

 mechanical hypothesis, and the notion of the 

 distinct agency of clastic fluids when mixed 

 together. The results were found entirely to 

 agree with both, or as nearly as could be ex- 

 pected from experiments of^uch nature. 



The facts mentioned in the 7th article, are 

 of great importance in a theoretic view ; for, 

 f the quantity of gas absorbed depend upon 

 mechanical principles, it cannot be affected 

 by temperature in confined air, as the mecha-
