A table showing the periodicity of the properties of many chemical elements, from the first English edition of Dmitrii Mendeleev's Principles of Chemistry (1891, translated from the Russian fifth edition). It is worth noting that the date, the presence of Gallium and the presence of Germanium this table indicate that it is not his original table. Thus it shows well his pattern recognition process, but not that he predicted the existence of Ga and Ge.
