This valuable dictionary is completed by the issue of the present volume which aims at furnishing, not an absolutely exhaustive, but a compre- hensive bibliography of philosophy under the rubrics noted above. The importance of such a work certainly justifies the great amount of time which Dr. Band has devoted to it during the last decade ; and he is to be congratulated on terminating, on the whole successfully, what must have been a very laborious task. This copious bibliography substantially increases the value of Dr. Baldwin's dictionary, and Dr. Band may rest assured that his work will certainly, as he modestly hopes, further re- search. It has a long career of usefulness in front of it ; but perhaps its greatest service will be to stimulate the production of complementary works traversing the saine ground more minutely and surveying it more systematically. For, although it is probably inevitable, and even just as well, that there should be one such work arranged throughout, like the present, alphabetically, such an arrangement has occasional serious dis- Ivantages. It must be admitted that the research student requires lore minute subdivision than the present work affords in some lirections, while the exclusively alphabetical arrangement of the livisions given breaks up chronological order without furnishing him with any logical clues. Thus, suppose one desirous to work up the Philosophy of History turned to this volume : he would discover, probably to his surprise, that there is no section devoted to the subject, and we do not envy him the task of collecting his authorities from alphabetical lists under the heads noted above. Even more surprising is the absence of a section on Sociology, and one might even have ex- pected another on Economics. The amount of material has, we are informed, been apportioned according to the relative importance of authors and subjects; but surely we are not to understand that the subjects just named are of no importance ; or to infer from the pro- portion of pages that Psychology is twice as important as Ethics, three times as important as the Philosophy of Beligion, or quite five times as important as Logic. No doubt the annual issues of the " Psychological Index" published by the Psychological Review which since 1902, the date to which the lists given in this volume extend, has been and will continue to be published as its supplement explains why we have an exhaustive bibliography in one direction, but it does not excuse the absence of any in others. Perhaps all the information is contained somewhere, but you certainly have to hunt for it. Where, for example, does one find Simmel's Philosophic des Geldes, or discover what Durk- heim or Tarde may have to say on social questions ? Then turning to authors : One could have wished that there had been a section " English philosophers : their works and works upon them ". As it is English thought is only treated separately under " History of Philosophy," where it is dismissed in four columns ; and although individual writers are treated of under " Philosophers : their works, etc.," it is not easy to see what raises a writer to the dignity of a section of his own. Why is there not one on Bradley as well as on Sidgwick ? Why is there a lengthy
