In the Eighteenth century British English, American English, and German all used "heavy capitalization," in which almost all nouns were capitalized. But there were no firm rules about which nouns were capitalized in which uses.
In English speaking countries, many writers and printers argued against this practice and the use of heavy capitalization fell from favor.

In Eighteenth century writing two different forms of the letter "s" appear in both printed and handwritten works. The regular "s" which is still used today and the "long S."
It's sometimes hard to see the difference between the long S and the letter F. The horizontal bar goes all the way through the vertical stem of the letter 'f' but only extends to the left of the vertical stem of the long S in printed works.

Printers would sometimes make decisions on which s to use based on what they had in their type drawer or simply on personal preference. It's not unusual to see the same document printed in different ways.
