Catalogue of Scientific Paws : Fourth Series (1884-1900). Com- piled
by the Royal Society. Vol. XV., "Fitting--Hyslop." (Cam- bridge University Press. f2 1064—The Royal Society's great author- catalogue of the world's scientific papers for 1884-1900 makes progress, though the staff has been reduced for lack of funds. This volume contains the titles of fifty-six thousand three hundred and twenty-five papers by ten thousand and forty-nine authors, and represents only about a sixth of the scattered contributions made to the sciences in the seventeen years. This fact alone shows the need for such a catalogue, though it must presumably be followed by a subject-index if it is to be used to the fullest advantage.
