Gelatin Process
the name given to the preparation of a photographic photographic dryplate by covering with an emulsion of salts in warm gelatin, and then sensitive drying. The plates are very much more sensitive than the old-fashioned wet plates, and have therefore made possible the photographing of rapidly moving objects. The exact composition of the gelatin emulsions varies considerably, and is kept secret by the different manufacturers, but generally speaking, the chemicals used in their manufacture include silver nitrate, ammonium bromide, potassium bromide and potassium iodide.

Used by Ovid as a surname of Cybele , in the place of mater, or magna mater; but it is better known as a surname of Venus , to whom Caesar dedicated a temple at Rome, as the mother of the Julia gens. 2026 Editor's Note: The subject is more commonly known as Aulus Gellius , rather than the inverted name order used here. His celebrated work Attic Nights (Noctes Atticae) serves as a vital commonplace book that preserves fragments from many classical authors whose original works are now lost. (Ed: BR 2026-06-04)

Genealogy
the systematical investigation and exhibition of the origin, descent , and relations of families (or their "pedigree"). Persons descended from a common father constitute a family. Under the idea of "degree" of relationship is denoted the nearness or remoteness of relationship in which one person stands with respect to another. A series of several persons, descended from a common progenitor, is called a "line." A line is either "direct" or "collateral." The collateral lines comprehend the several lines which unite in a common progenitor. For illustrating descent and relationship genealogical tables are constructed , the order of which depends on the end in view. The common form of genealogical tables places the common stock at the head, and shows the degree of each descendant by lines. Some tables, however, have been constructed in the form of a tree, in which the progenitor (German , Stammvater, "trunk-father ") is placed beneath as if for a root.

General Education Board
2026 Editor's Note: This page uses language about race that was commonplace when the book was published and is offensive by today's standards. The text has been left exactly as it was printed, rather than cut or softened, so that the historical record — including how ordinary such language once was — is preserved. (Ed: ET 2026-07-22) an organization established for the purpose of distributing gifts made by John D. Rockefeller for educational purposes, and chartered by Congress in 1903. Over $50,000,000 have been given by Mr. Rockefeller to the Board. The Board generally makes its gifts to agencies and institutions already in existence and does not undertake independent educational work. The gifts of the Board are mainly devoted to the promotion of practical farming in Southern States; to the establishment of public high schools in Southern States; to the promotion of institutions of higher learning; and to schools for negroes. For all these purposes the Board has expended large sums, which, of course, were assigned only after a careful study of the needs and conditions of the recipients. The investigations which preceded the gifts of the Board were perhaps of as great importance to the development of education in the United States as the gifts themselves. The Board consists of 17 members and maintains headquarters in New York City. In 1920 the president was W. Buttrick, and the secretary, A. Flexner.
