TRANSCRIBER’S NOTE
Original spelling and grammar have been generally retained, with some exceptions noted below. Original printed page numbers are shown like this: {52}. Footnotes have been relabeled 1–3, and moved from within paragraphs to nearby locations between paragraphs. A few missing full stops were inserted, for example after “avoided” on page [49]. The transcriber produced the cover image and hereby assigns it to the public domain. Ditto marks have been removed and replaced by repetitions of the referenced text. Original page images are available from archive.org—search for “photolithography00frit”.
There are twenty-four advertisements at the end of the book. A new heading is added at the beginning of that section.
