Classics.—Dr. Edward Harwood published his "View of the various editions of the Greek and Roman Classics" in 1790. He was followed in 1802 by Thomas Frognall Dibdin, whose work was much enlarged, and reappeared in several editions; the fourth and best being published in 1827 (2 vols. 8vo.). J.W. Moss published his "Manual of Classical Bibliography" in 1825, 2 vols. 8vo. Henry G. Bohn's General Catalogue, Part II. Section I. 1850, contains a valuable list of Greek and Latin Classics. Engelmann's Bibliotheca Scriptorum Classicorum et Græcorum et Latinorum (1858) is an elaborate work on the subject, and Professor John E.B. Mayor's translation and adaptation of Dr. Hübner's Bibliographical Clue to Latin Literature will be found to be a very useful handbook.

Commerce.—See [Trade].

Dialects.—Mr. J. Russell Smith published, in 1839, a useful "Bibliographical List of the Works that have been published towards illustrating the Provincial Dialects of England" (24 pages). When the Rev. Professor Skeat started the English Dialect Society, he at once laid the foundation of an extensive Bibliographical List to include MSS. as well as printed works. This Bibliography is being published by the Society in parts.

Dictionaries.—William Marsden printed privately, in 1796, a valuable "Catalogue of Dictionaries, Vocabularies, Grammars, and Alphabets."

Dictionaries.—Trübner's Catalogue of Dictionaries and Grammars (1872, second edition 1882) is a very useful work. H.B. Wheatley's account of English Dictionaries was published in the Transactions of the Philological Society for 1865.

Drama.—A notice of some books in the English Drama will be found in Chapter IV. The Bibliothèque Dramatique de Mons. de Soleinne (1843-44, 5 vols.), with its continuation to 1861, is a splendid Catalogue, in which the books are fully described, with valuable notes and preface.

Earthquakes.—Mr. Robert Mallet's Bibliography of Earthquakes will be found in the British Association Report for 1858, and Mons. Alexis Perrey's Bibliographie Seismique in the Dijon Memoires for 1855, 1856, and 1861.

Electricity.—Sir Francis Ronalds' Catalogue of Books and Papers relating to Electricity, Magnetism, and the Electric Telegraph (1880) contains a large number of titles. O. Salle's Bibliography of Electricity and Magnetism, 1860 to 1883, was published in 1884.

Entomology.—Dr. Hagen's Bibliotheca Entomologica (Leipzig, 1862-63) is a carefully compiled and useful book.
