----. _Catalogue of Scientific Papers, 1800-1900, Subject Index._
London, 1909, vol. 2.

This subject index was started in 1908, and by 1914 three volumes (the
third in two parts) had been published; however, this subject index was
never completed. Volume 2, titled _Mechanics_, has some 200 entries
under "Linkages." It is interesting to note that both of the Royal
Society's monumental catalogs grew out of a suggestion made by Joseph
Henry at a British Association meeting in Glasgow in 1855.
