_The London Telegraph_:--"In 'The Humour of the Underman' there is a delicacy, a skilfullness, an ease of manner, and a consummate sense of style. Here is the short epigrammatic way of putting things which is Emerson's way, but the successive sentences are less staccato than in the work of the Concord Sage; there is added to it something of the delicacy, the ease, the grace of the French." THE INVINCIBLE ALLIANCE _Austin Harrison, Editor of The English Review_:--"Mr. Grierson's essays are masterpieces of lucid expression and condensed though. In 'The Invincible Alliance' he puts his index finger on the weak places--on snobbery on politics, on music, on the clergy, on the English point of view, which is twenty years behind Continental thought.... We believe him to be absolutely right." _Dr. Samuel P. Orth, Professor of Political Science at Cornell, in a page review of the book in the N. Y. Times_:--"In 'The Invincible Alliance' Mr. Grierson touches prophetic heights. His analytical gift is a sort of intellectual clairvoyance." ILLUSIONS AND REALITIES OF THE WAR _The New York Sun_:--"Mr. Grierson's volume on the war is the rarest book of the year." _The Brooklyn Eagle_:--"A work of marvellous power." _The Independent_:--"Keen observation, trenchant criticism, and a conciseness of style combine with unusual force in Mr. Grierson's latest volume on the great war." _The Boston Transcript_:--"In 1913 Mr. Grierson wrote a volume of essays called 'The Invincible Alliance' in which he outlined very clearly the dangers which lay before the two great English-speaking nations. Re-reading these essays in the light of the last four years we can see that Mr. Grierson looked even more deeply into the future and that he predicted much which has come to pass since the war began." _The Herald, Washington, D. C._:--"Since the publication of the 'The Invincible Alliance' nothing has appeared in book form to surpass the trenchant vigour and illuminating insight of 'Illusions and Realities of the War.'" LA VIE ET LES HOMMES _M. Sully Prudhomme, of the French Academy_:--"J'ai trouvé ces méditations pleines d'aperçus profonds et sagaces. J'ai été frappé de l'originalité puissante de la pensée de l'auteur." MODERN MYSTICISM _Maurice Maeterlinck_:--"This volume is full of thoughts of the very highest order. You have deliciously and profoundly surprised me. You have said so many things which I should like to have written myself." _A. B. Walkley, dramatic critic of the London Times_:--"Modern Mysticism is an original and delectable book."
