Annual Report of the Board of Regents of the Smithsonian Institution, Showing the Operations, Expenditures, and Condition of the Institution for the Year Ending June 30, 1900.

lxv, 759 pp. 8vo. While at first blush the title would seem to indicate that this is a rather dry annual report, a closer examination reveals numerous engraved plates and photogravures, as well as an appendix full of important textual references to important topics of the day, such as: the May 28, 1900 solar eclipse; geology; Mars; aeronautics, flight, and zeppelins; electricity; the photography of sound waves; African exploration; endangered species; archaeological discoveries in Mesopotamia; yellow fever; etc.
