Late Director of the Natural History Museum, and President of the Royal Zoological Society. A Personal Memoir.

By CHARLES J. CORNISH, M.A., F.Z.S. With Photogravure Portraits. 8vo. 8s. Ed. net. PALL MALL GAZETTE.—"The late President of the Zoological Society was a man of so many interests that this biography should be welcome everywhere. .. The portraits are a capital addition."

ACADEMY._"Verily a life worth living, and worthy of remembrance.”

SPECTATOR.-"Flower's youngest son has contributed two chapters on his father's early life, and his widow some personal details of his last years. . . . An address which Sir William gave at the Church Congress at Reading admirably expounds the bearings of science on religion and the reasons for modifying some of our theology. ... The Sunday opening of museums, which Flower always urged . . became an accomplished fact, and the long-fought question was silently settled by a Resolution of the House of Commons in 1896.”

COUNTRY LIFE.—“One of those rare books which is precisely what it pretends to be."

LAND AND WATER.—“ It is interesting to all sportsmen, for not only was Sir William author of the masterly “The Horse : a Study in Natural History,' and an expert taxidermist, but the results of his system of exhibiting, labelling, and arranging the skeletons of animals are seen to-day in every up-to-date museum in the world. Sir William Flower's courtesy freed him from the difficulties which had beset his predecessors, he had 'the temper of a saint, and the manners of an ambassador.'"
