Philadelphia, PA, The Author, 1873. 8vo (22.5 x 14.9 cm). 32 pp. (first seven with Roman page numbers); eight finely engraved, tissue-guarded plates by the author. Original printed wrappers.

The rare start of a seldom-seen work (there are no auction records after 1977). The rear wrapper, not usually preserved, contains a prospectus of the whole work, and conditions of the various editions offered. This part is of the plain edition, but as often with Tryon's publications, a hand-coloured version as well as one with plates in double suite, uncoloured and coloured, were available too (this one in a limited edition of 25 copies). The work was completed with 208 pp., and 44 plates. This work should not be confused with a similar-titled work by Timothy Conrad. Some light wear to the wrappers, otherwise very good. Nissen ZBI, 4173.
