The Periodic Table is so much part of our Chemical education that we forget that for many decades after the birth of 'modern' chemistry no such thing existed. Various attempte were made to classify the elements, culminating in Mendeleev's brilliant achievement of not only categorising what there was known about the elements, but also predicting what was not. The four extracts here give some of the flavour of the thoughts of the times.
