First published in London in 1819, with the first American edition appearing in 1820. An important and innovative work of popular science education, a series of “conversations” covering in a pretty comprehensive way mechanics (including hydrostatics and pneumatics), optics, astronomy and other related topics. The plates include astronomical charts showing the planets out to Herschel. (The interlocutor Mrs. B. speculates as well whether Mercury might be inhabited by creatures adapted to its harsh climate.) Nice early Boston bookseller ticket for R. P. & C. Williams, Cornhill Square, on the front paste-down.
