The paper is very fully illustrated, having 

 seventeen cuts in the text and three plates, 

 illustrating the dental and cranial characters of 

 the forms recognized. Many of the figures of 

 the skulls are reproductions from photographs.

Elementarcurs der Zootomie in funfzehnVorlesun- 

 gen. Von Dr. B. Hatschek und Dr. C. J. 

 CoRl. Jena, Gustav Fischer. 1896. 

 This new zootomy of viii. and 104 octavo 

 pages, 18 plates and 4 text figures comes to us as 

 a surprise after waiting so long (and apparently 

 in vain) for the Vierte Lieferung of Hatschek's 

 Lehrbuch der Zoologie. It devotes four lec- 

 tures to Salamandra maculosa, one to Eana 

 temporaria, two to Anodonta mutabilis, two to 

 Helix pomatia, two to Astacus fluviatilis, two 

 to Periplaneta orientalis, one to Lumbricus ter- 

 restris, and one to Hirudo medicinalis. Apus 

 cancriformis and Hydrophilus piceus each con- 

 stitutes an ' Anhang ' to the eleventh and thir- 

 teenth lecture respectively. Of the plates four 

 are devoted to the Salamander, one to Rana, 

 two to Anodonta, two to Helix, three to Asta- 

 cus, one to Apus, three to Periplaneta and Hy- 

 drophilus, one to Lumbricus and one to Hirudo. 



The general plan of the book is to indicate 

 first in a table or two the systematic position 

 of the animal to be studied ; then, as an intro- 

 duction, give a brief account of the organiza- 

 tion and relationship of the group to which the 

 animal belongs, and then give an account of the 

 external and the internal anatomy of the ani- 

 mal, preceding the accounts of the several sys- 

 tems of organs with brief laboratory directions. 

 Practically it is a meager laboratory guide dis- 

 tributed in a text-book that aims to give the 

 beginner a general survey of the animal king- 

 dom in as short a time as possible, and with 

 material most easily obtained at Prague. 



The fish is omitted because a profitable study 

 would require too much time, and the Coelen- 

 terata, Echinodermata and Ascidians are merely 

 alluded to in the lectures, because laboratory 

 work on these groups is impracticable in ' eines 

 ganz elementaren Kurses.' When we read 

 the lectures, the technical notes and examine 

 the figures we exclaim what is a ' ganz elemen- 

 tar Kursus ' at a university ! 



In the preface we are told this elementary 

 course in zootomy is the outcome of a ten-years' 

 experience at the University at Prague and that 

 with respect to ' Form, Inhalt und Ausdehnung' 

 it represents quite accurately the annual course 

 of lectures and exercises given at the Univer- 

 sity. The object of the course, it is stated, is to 

 acquaint the beginner with a mass of facts that 

 in connection with the lectures upon theoreticalj 

 zoology shall constitute a foundation for more| 

 advanced study. 



All of this we are assured can be attained in 

 fifteen two-hour periods ! This will no doubt ; 

 be welcome news to the lovers of the ' 14 weeks ' 

 courses which many of us mention with so : 

 much respect. Personally we have no time to 

 waste upon such courses at our colleges or uni- 

 versities, and we even have our doubts as to] 

 their value in our high schools. 



It is the unanimous verdict of careful obser-^ 

 vers that the American student in general is 

 not a whit inferior to the German student, and 

 yet these authors would have us believe their 

 beginners in zoology studj?^ ' in fruchtbringender 

 Weise ' the vascular and nervous systems of
