MACMILLAN & CO.'S LIST. SIR WILLIAM HENRY FLOWER, K.C.B.,
F.R.S., LL.D., D.C.L., 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 THE NATION (U.S.A.). -"For details of the life we must refer to the volume. ... Flower was a man of noble presence, striking manly beauty, and of a most kindly and unaffected nature. . . . His marriage proved ideal in its results. . . . He was a self-sacrificing worker, a miracle of persistent, steady devotion to the profession he had at heart . . He was . . . the first man in Great Britain to elevate the keeping of a museum into one of the higher professions ; was one of the first in the world to introduce modern ideas into the administration of museums, and the originator of many most important advances. . . . He was an excellent comparative anatomist, a specialist in the first rank of students of the Cetacea ... a lover of poetry, of outdoor life, of children, and animals. Not a genius, he was lamented more than any scientist of his generation, in his own country, and by those of other lands who had had the privilege of his friendship, and knew his worth in spite of his modesty. . . . It was well that a memoir should be written to keep him and his work in remembrance."
MUSEUMS JOURNAL.-" That which will most strongly interest readers of the memoir, and all who have personal recollection of Sir Wiliam "lower, is the character of the man. . , . No one can read the simple and beautiful chapter (at the conclusion of the memoir) in which Lady Flower writes of the end of that noble and unselfish life without emotion,"
