His chief work, embodying investigations into the laws of chemical affinity, still exercising a most powerful influence 

 on this question. ' Setting out, like Bergman, with the hypothesis that affinity is identical with gravity, he went on to 

 emphasise the undeniable conclusion that the forces of chemical affinity, like those of general attraction, must be pro- 

 portional to the masses of the acting substances. The further deductions from his principle he worked out with a 

 masterly clearness in his Essai de Statique chimiqm.' Prof. E. v, Meyer.
