‎Scarce first edition of this importent work which is a large extension of Meyer's classic paper of 1870, in which he independently of Mendeleev, discovered that the properties of the elements are a periodic function of (or vary in a periodic manner with) the atomic weight - the Periodic Table.""The significance of atomic weights in the demonstration of chemical periodicity, and the suspicion that some atomic weights were not accurate, led Meyer and Seubert to examine critically and to recalculate all atomic weights then considered importent. Their study was published in 1883 (the work offered). All atomic weights were referred to the standard of unity for the atomic weight of hydrogen, a standard that Meyer championed.....In 1903 the newly created International Commission of Atomic Weeights decided to publish parallel tables based on H=1 and O=16, a practice followed for many years.""(DSB IX, pp. 351-352).‎
