 Lehrluch der vergleichenden Histologie der 



Tiers. Von Dr. Karl Camillo Schneider, 



Privatdozent an der Univ. Wien, mit 691 



Abbildungen im Text. Jena, Verlag von 



Gustav Fischer. 1902. 



This comparative histologj' is another in- 

 stance of the astonishingly brief time in which, 

 in Vienna, a great work may be brought to 

 completion. The heavy volume of 939 pages 

 contains also a bibliography of 30 pages and 

 an index. 



The work is divided into a general and a 

 special part. The plan has been to bring to- 

 gether in the general part the weightiest re- 

 sults for comparison by a presentation of the 

 leading points of view, while in the special 

 part leading groups are treated by taking up 

 typical representatives in detail. 



This plan has not been carried out com- 

 pletely, however. A number of groups, espe- 

 cially the Tunicata, and still further the 

 Trematoda, Aeanthoeephala, Rotatoria, Si- 

 phunculoidea, Cephalopoda, Myriapoda, Arach- 

 noidea, Scyphomedusa, Ophiuroidea, Eehi- 

 noidea, Bryozoa, Brachiopoda, typical fishes, 

 reptiles and birds, have not been considered at 

 all or only superficially. Even the remain- 

 ing types have not been worked up with the 

 completeness one might wish. Still the work 

 is a remarkable and valuable one. The text, 

 to a considerable extent, is based on the re- 

 searches of the author, while the literature, 

 to which extensive reference is made, has 

 served chiefly as control. Wherever the 

 author has been dependent on literature
