properly distributed throughout the cropping 

 season, to make agriculture reasonably cer- 

 tain without the aid of irrigation ; and the 

 people of the country believe that the hot 

 and dry winds have more to do with short- 

 ages of crops than lack of rainfall. The 

 capacity of the surface streams being limited 

 (the Arkansas and South Platte are already 

 made to give up most of their water before 

 leaving Colorado), a valuable other resource 

 for irrigation is derived from the use of the 

 subterranean or "undersheet" water, with 

 which the sand and gravel deposits in the 

 river valleys of considerable width and 

 unknown depth arc charged. Much of this 

 is obtained by means of open subflow 

 ditches. In other cases it has to be pumped. 

 In regions where this is not available, the 

 people must depend upon deep wells of 

 limited capacity, the storage and immediate 

 use of storm waters, and the flow of artesian 

 wells. 



The Journal of the College of Science of 

 the Imperial University of Japan, \o\. IV, 

 Part I — published by a committee of four 

 professors, three of whom are Japanese — 

 cohtains seven articles on subjects of biol- 

 ogy and physiology, all by Japanese writers. 

 All are distinguished by great merit, but 

 are of too technical a character to be sus- 

 ceptible of detailed notice in a popular 

 journal. Prof. K. Mitsukari offers a study 

 on the embryology of the turtle, in which 

 many notable features hitherto overlooked 

 are presented. Mr. Kamakichi Kishinonge 

 describes the pulmonary lamellae of certain 

 genera of spiders and their development, 

 which he suggests may be from some aquat- 

 ic arthropod, as limulus. Mr. A. Oka de- 

 scribes a new species of fresh-water poly- 

 zoa. A new fungus enemy of the mulberry 

 tree is described by Mr. Nobujiro Tanaka. 

 The Irritability of the Stigma is shown by 

 Mr. M. Miyoshi to have a relation to cross - 

 fertilization. A paper by Mr. Masamaro 

 Inaba on the Development of Suprarenal 

 Bodies in the Mouse contains much of in- 

 terest to physiologists. All these papers 

 are abundantly illustrated in the highest 

 style of lithographic art, with colors. 



In his lecture on Les Proges de V Anthro- 

 pologic (Paris, De Saye & Son, printers), the 

 Marquis de Nadaillac endeavors to refute 

 the theory of evolution. It is no slight tes- 



timony to the solid foundation on which that 

 theory has been established in our modern 

 philosophy that so learned and earnest a 

 writer has not been able to add one to the 

 arguments which English students met and 

 answered long ago. 



Two studies of general interest in the 

 Amm-ican Journal of Psychology for April 

 are those of Dr. E. W. Scripture on Arith- 

 metical Prodigies and Mr. Ilerbert Nichols 

 on the Psychology of Time. In his paper 

 on Arithmetical Prodigies, Dr. Scripture first 

 gives an account of the persons themselves, 

 with a bibliography of the subject; and 

 afterward undertakes to make such a psycho- 

 logical analysis of their powers as will help 

 in the comprehension of them, and furnish 

 hints to the practical instructor in arith- 

 metic. 



The most important paper in Part XYIII 

 of the Proceedings of the Society for Psy- 

 chical Research is that of Jlrs. Henry Sidg- 

 wick on the Evidences for Clairvoyance. 

 Other curious studies are those of Baron von 

 Schrenck-Notzing on Thought-transference ; 

 Mr. Thomas Barkworth on Automatic Writ- 

 ing ; and M. Leon Marrilier on Apparitions 

 of the Virgin in the Dordogne. Prof. Will- 

 iam James's Principles of Physiology is re- 

 viewed at length by F. W. H. Myers. London. 



Dr. William W. Parker, of Richmond, 

 Va., endeavors, in a paper on Instinct in Ani- 

 mals and Intelligence in Man contrasted, to 

 show that there can be no comparison be- 

 tween the two, but that the matter is one of 

 contrasts and antitheses : that in the ani- 

 mal, intelligence is limited ; in man unlimit- 

 ed ; that man's highest qualities or percep- 

 tions have no existence even in embryo in 

 animals ; and that " not one, not a thousand, 

 links can bridge the chasm between the in- 

 telligence of animals and the intelligence of 

 man." 



Insects and Insecticides, a practical manual 

 concerning noxious insects and the methods 

 of preventing injuries, is designed by the 

 author, Clarence M. ^yeed, who is also hia 

 publisher (Hanover, N. H.), for the use of 

 the farmer, fruit-grower, floriculturist, and 

 housekeeper. It has been prepared to fur- 

 nish these persons with a concise account of 

 the more important injurious insects with 

 which they have to contend, together with a 

 summary of the latest knowledge concerning
