Note 1 — I THE AMERICAN JOURNAL OF SCIENCE FROM 1818 TO 1918

The statements given are necessarily much condensed, without an attempt to follow all changes of title; furthermore, the dates of actual publication for the academies given above are often somewhat vaguely recorded. For fuller information see Scudder’s “Catalogue of Scientific Serials, 1633–1876,” Cambridge, 1876; also H. Carrington Bolton’s “Catalogue of Scientific and Technical Periodicals, 1665–1882” (Smithsonian Institution, 1885). The writer is much indebted to Mr. C. J. Barr, Assistant Librarian of Yale University Library, for his valuable assistance in this connection.
