This appears to be the second catalogue of a U.S. exhibition of rare books on any scientific subject, following John Shaw Billing's catalogue of his exhibition of books from the Army Medical Library at Johns Hopkins Hospital in 1899. (See GM 13587.) Bolton's briefly annotated catalogue records a selection of 110 highlights from what was presumably Bolton's much larger private library. For Bolton's "select" bibliography of chemistry and the history of chemistry, containing 12,031 entries, see No. 11425.
