Chemistry no mystery; or, A lecturer's bequest. Being the subject-matter of a course of lectures, delivered by an old philosopher, and taken in short-hand by one of the audience, whose name is not known

I have in my library several chemistry textbooks from before 1860, but "Chemistry No Mystery" is not one of them.  Reflecting as they do an approximation of the chemistry known at the time, they provide insight about the history of both science and pedagogy. I learned about this one from my friend Ron Perkins, a skilled chemical demonstrator, and "Chemistry No Mystery" is the most demonstration-oriented of the old textbooks I have seen.
