Mendeléeff's Vertical Table (Q&Q's Spelling)

Quam & Quam's review paper states:

"Mendeléeff's first table was a vertical arrangement in which the elements could be read in order of increasing atomic weight from the top down and in successive series from left to right. The fist column consisted of H and Li; the second, of Be to Na; the third started with Mg.

"An improved form of this table, shown below, appeared in 1872: H occupied the first position separately. The vertical series in order were Li to F, Na to Cl, K to Br, etc., causing the halogens to appear in the same bottom series, while H, Li, Na, Cu, Ag, and Au constituted a midway series, and K, Rb, and Cs formed the topmost series."
