I first came into contact with the long s while reading (IIRC) Antoine de Lavoisier's memoirs (or papers?) on the nature of diamond. It was very unnerving to read, as I couldn't see the difference with an "f" before enquiring more about it, and reading the wikipedia article. I couldn't find the exact reference, but the book was along the lines of that one (French): https://books.google.fr/books?id=yr3OAAAAMAAJ&pg=PA22 https://books.google.fr/books?id=yr3OAAAAMAAJ&pg=PA22
