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

 on this question. ' Setting out, like Bergman, with the hypothesis that affiuity 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 cMmique.' — Prof. E. v. Meyer.

Final Edition. ' Along with the absolute thoroughness which we also admire in his experimental work, clearness of 

 description is united in this book with precision of expression. He did not merely confine himself to the simple exposition 

 of known facts, but criticised the experiments from which these were deduced with perfect impartiality. His text-book 

 remained a pattern for others during the succeeding decades.' — Prof. E. v. Meyer.
