which it is especiallj^ fitted ; library facili- 

 ties ; scholarships and fellowships open to 

 students ; lists of apparatus invented, re- 

 searches published and in preparation, and 

 other publications by the instructors. 



II. The second part of the annee is 

 headed ' Bibliographie,' and consists of 

 analyses of nearly 200 books and articles 

 (pp. 257-528), of a description of new ap- 

 paratus (529-53i), and of a necrology (535- 

 638). 



III. In a third part is placed a biblio- 

 graphical table of 1217 titles, provided with 

 an index of authors. The classification of 

 this bibliography, which differs slightlj^ 

 from that of the analyses of the second part, 

 is the following : Psychological treatises ; 

 articles on general psychology; normal and 

 pathological anatomy and histology of the 

 central nervous system ; physiologj^ of the 

 nervous sj^stem ; psychological methods ; 

 physiology and anatomy of vision ; visual 

 sensations ; audition ; sensations of the 

 skin ; gustatory and olfactory sensations ; 

 movements ; fatigue ; emotions ; memory ; 

 psychometry; attention ; association ; indi- 

 vidual psychology and character ; scholastic 

 psychology (pedagogy) ; heredity and evo- 

 lution ; criminal psychology ; hypnotism, 

 suggestion and sleep ; aphasia ; mental and 

 nervous pathology ; anthropologj' ; com- 

 parative psychology. 



The first five articles of part I. do not 

 represent all the work accomplished in con- 

 nection with the laboratory of the Sor- 

 bonne. A full list, given on p. 179, includes 

 twelve further titles of papers which have 

 been published elsewhere, and which are 

 therefore merely analyzed in part II. It is 

 proposed to retain as a permanent feature 

 of the Annee the ' general review on some 

 important question,' represented this year 

 by the paper on American laboratories, in 

 such a manner as to gradually work through 

 the entire field of psychology. General re- 

 views on psychometry, on the graphic 



method, and on the psychology of vision, 

 are announced as probable.

 pp. 501, plates XXXVII. , figs 34. 

 In July, 1892, the present Geological 

 Survey of Iowa took the field, and up to 

 date three volumes have been issued. 

 These are the Annual Report for 1892, 

 issued 1893; the Coal Deposits of Iowa, 

 issued 1894; and the Annual Eeport for 

 1893, the volume here under consideration. 

 Iowa is more widelj^ known for its agi'i- 

 cultural than for its mineral resources, but 

 the latter are none the less of extreme 

 importance. In coal there is a vast pro- 

 du-Ctive area and an annual output of five 

 million tons. The great beds of gypsum 

 near Fort Dodge are now being adequately 

 developed, and in not a few places through- 

 out the State the less conspicuous indus- 

 tries of brick, pottery and building stone 

 are coming into prominence. It is not in- 

 tended to imply that agriculture is in any 

 degree less benefited by a geological survey 

 than these other industries, and the reports 

 in question give evidence that this fact has 

 been well appreciated by the State Geologist. 

 The wise manager in an office of this kind 

 carries on, behind the breastworks of eco- 

 nomic geology, all the purely scientific work 

 that his constituencj' will bear. Professor 

 Calvin seems to have nicely adjusted these 

 relations. 



Passing over the routine reports, the work 

 before us contains the following special 

 papers :

 posits of the Sioux Valley,' pp. 101-114. 

 The classification of the cretaceous is more 

 accurately carried out for this region than
