His findings were published in Über die neueren
Gegenstände in der Chemie (1792–1802) and Anfangsgründe der Stöchiometrie or Messkunst chemischer Elemente (1792–1794), but a considerable period of time elapsed before they were fully acknowledged. This was partly because some of his work was

Evidence for the existence of atoms was inferred from the law of definite proportions proposed by him in 1792. Richter found that the ratio by weight of the compounds consumed in a chemical reaction was always the same. It took 615 parts by weight of

He was thus led to conclude that chemistry is a branch of applied mathematics and to endeavour to trace a law according to which the quantities of different bases required to saturate a given acid formed an
