vesicles are circular in outline, concave from within, and form round- 

 ed elevations on the outside where the cups come in contact with the 

 outer layer of the epiblast. The optic vesicles are clearly outlined in 

 Squalus acanthias before the medullary groove is fairly established. 

 Related to these are other depressions on the cephalic plate. These 

 are circular depressions formed in the same manner as the optic vesi- 

 cles but behind them as if the process of eye-formation were repeating 

 itself serially. These the author calls accessory optic vesicles. If 

 the views expressed are true we have a multiple-eyed condition in the 

 embryos of these animals and the author employs these facts as evi- 

 dence of the origin of eyes from segmental organs. The anterior 

 accessory vesicles the author subsequently identifies as the protons of 

 the pineal outgrowths which are thus rendered homodynamous with 

 the lateral eyes. We await with interest more substantial evidence 

 than that afforded by the very unsatisfactory diagrams which accom- 

 pany the paper. Certainly in matters of this sort we may hope for the 

 confirmation of serial sections. 



The psychological Review. 



In accordance with the announcement made some time since 

 and which has awakened much interest, the first issue of this Journal 

 appears promptly with the new year. 



Professors J. M. Cattell of Columbia and J. M. Baldwin of 

 Princeton issue the periodical with the active cooperation of a very 

 able corps of associates from America, England, Germany and 

 France. That the appearance and make up is all that could be de- 

 sired goes without saying. 



It is perhaps inevitable in the present transitional stage of psy- 

 chology in America, when almost all our better colleges offer some 

 experimental work, which is dominated largely by the old ideals, that 

 the product in the form of printed results shall have a sketchy and 

 unsatisfactory character. Such a periodical as the present one should 

 do much to set high ideals for such work. This place has been worth- 

 ily filled for some time by the American Journal of Psychology, though 

 the difficulties under which it. has labored made themselves manifest 

 at times. 



It is hardly complimentary to American intellectual independ- 

 ence to note that we are quite unwilling to accredit or assist any at- 

 tempt originating here until the verdict of certain authorities abroad 

 has been heard. 



The present issue is chiefly noteworthy in its promise for the 

 future.
