The following works are by Gray, or were part of the propaganda surrounding his proposals. A couple of notes: 1) The texts at archive.org are a little hard to work with, but they appear to be complete, which is much more than can be said for the versions at Google Books. I have reported a number of texts missing whole chapters, including one of the books by Gray. So far, I have yet to see a single instance of corrective action in that archive. 2) The "rough pdfs" are genuinely rough, though they are readable at proper magnification. They were provided by a friend who probably went to far too much trouble for such marginal material, but to whom I am very grateful. I hope to have clear, plaintext versions completed for those items soon. 3) An electronic version of the Lecture is in the works as well. I would like to include it in a collection of texts related to the spring course.
