themes. It is the fertility and pertinence of 

 illustration, the masterly marshaling of facts, 

 the discernment that detects the crucial points 

 of difPerence and is not deceived by the 

 current or surface view of things — these will 

 be the traits that will measure the value of the 

 work to the progress of psychology. Accord- 

 ingly, the volume may be set down as one of 

 those that has a literary style and a capacity 

 to make the reader think. He will not always 

 think as the writer does; but he will never 

 listlessly muse as his eyes scan the pages, nor 

 idly accept as dogma what is offered to his un- 

 derstanding. 



The scope of the volume may be said to in- 

 clude those phases of discussion that deal 

 with thought as a whole; with the succession 

 of waves of consciousness and the composition 

 of these waves. Habit, memory, imagination, 

 dreams, originality, language, reasoning, at- 

 tention, willing, emotional and esthetic prod- 

 ucts, are all subjects of chapters with head- 

 ings the appropriateness of which the reader 

 will recognize only as he proceeds. There 

 is no detailed study of the senses nor of the 

 nervous system; for it is maintained that sci- 

 ence has progressed only so far that general 

 illustrations of these alone find a place in the 

 psychology now possible. The results of the 

 experimental or laboratory psychology are re- 

 garded as too incomplete and too artificial to 

 modify more than incidentally the more vital 

 considerations that flow from experimental 

 introspection. Genetic sources are considered; 

 though the topic is the mind of man, and 

 thus deals but little with the minds of ani- 

 mals. 



The opinion is frequently heard that, in 

 spite of the enormously increased attention 

 that is now given to psychological matters, 

 and in spite of the conviction, only occasion- 

 ally challenged, that psychological principles 

 have great potency to guide the practical 

 path of culture and education, yet so little 

 that is tangible enough to be summarized and 

 entered to the credit side of the progressive 

 inventory of science can be written upon the 

 pages allotted to psychology. Apart from the 

 pertinent query as to how far such difiiculty 

 is itself significant, it may well be concluded 



that psychology might profit by a shaking up 

 rather than by efforts to harmonize essentially 

 opposed tendencies; that the time has come, 

 not for repairing old clothes, but for making 

 new ones. Those who feel that there is some 

 force in such considerations, as well as many 

 others whose interest in matters psychological 

 is less comprehensive or less professional, will 

 find much food for reflection — and food pleas- 

 antly prepared and vigorous withal — in the 

 pages of Mr. Spiller's notable work.

In the future, as in the past, it is not im- 

 probable that works dealing with the unicel- 

 lular plants will continue to be published in 

 botanical journals, and papers dealing with 

 the bacteria will appear sometimes in one and 

 sometimes in another, or that monographs on 

 the Protozoa will still be brought out in strictly 

 zoological periodicals. This will involve 

 the continuation of an old bibliographical 

 difiiculty for those investigators whose prob- 

 lems carry them into the more general aspects 

 of the unicellular organisms. These diffi- 

 culties may, however, be considerably lessened 

 if students of the several groups mentioned 

 would send their contributions to the Archiv 

 filr Protistenhunde. This is a journal de- 

 voted exclusively to the publication of papers 

 upon the unicellular organisms, and under the 

 direction of one of the most capable students 

 of these forms. It is sincerely to be hoped 

 that the object of the new journal will be ful- 

 filled, and that students of the unicellular 

 plants and animals in America will interest 

 themselves in the project and contribute to its 

 support. 



Two numbers of the Archiv have already 

 appeared, and the contents of the first give an 

 adequate view of the scope of the periodical. 

 In this there are six contributions which vary 

 in Jength from two or three pages, as in 

 Prowazek's note on Trichomonas hominis, to 

 nearly eighty pages in Lohmann's excellent 

 monograph on the Coccolithophoridse or coo-
