On Atomic Weights—Elemental Properties Relationships, by Meyer

3 ON ATOMIC WEIGHTS—ELEMENTAL PROPERTIES RELATIONSHIPS, BY MEYER (1870) 

Mendeleev s Keplerian s ideas of periodicity were nevertheless also advanced, by another contemporary scientist, Meyer (1870), yet lacking somehow of elemental prediction in terms of atomic weight and or atomic number position

of those atomic weight probably derive from the equivalent weights, in total 56 elements. Besides H, it is missing only Y, Eb, Ce, La, Di, Th, U, Jg, with no atomic weight which was known and even some of which equivalent was undiscovered. The Table 1.10 is actually identical to the one given by Mendeleev (1869a). 

While the elements will follow the nine vertical rows (to the first until the last depending by their molecular weight), the horizontal rows include the natural families. In order to obtain this arrangement, certain elements (of which atomic weight was found almost equal and which probably was not very carefully determined) have to be rearranged tellurium before iodine, osmium before iridium and platinum, and these before the gold.
