The theatrical alphabet. [electronic resource] : Containing A Catalogue of several hundred Parts (both Mens and Womens) in different Plays and Farces; with the Number of Lengths noted that each Part contains, carefully disposed in alphabetical Order, and accurately distinguished by initial Letters, denoting whether they are in a Tragedy, Comedy, Opera, Farce, &c. The Number of Lengths are justly calculated, as they are performed at the Theatres Royal; with a Vacancy reserved to insert many more, as they may occur in new Pieces, or otherwise.
