Why would Mendeleev and other chemists of his time arrange elements in the periodic table in order of atomic masses instead of in order of atomic number?

In the 1800's scientists didn't know that atoms even had electrons, let alone protons and neutrons. All they had was a way to measure the relative masses of the elements so that is what they used. It worked out quite well anyway.

I'm pretty sure atomic mass is directly related to the atomic number.
