Leipzig, Breitkopf & Härtel, 1883. Contemp. hcalf. Raised bands, gilt spine, titlelabel with gilt lettering. X,245,(1) pp. Internally fine and clean.

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). …
