The " Journal of Physiology " is the 

 recognized register of physiological research 

 by English-speaking investigators, and pre- 

 sents as they are accumulated the results of 

 the studies of those distinguished cxperi- 

 mentists, on either side of the ocean, whose 

 discoveries have been the means of con- 

 tributing so much to the intelligent and effi- 

 cient treatment of human affliction. The 

 present number contains papers by G. F. 

 Yeo and J. W. Barrett, S. Ringer, II. Sew- 

 all and D. W. Stciner, J. A. Mc William and 

 T. Wesley Mills, on various aspects of the 

 heart ; S. Ringer and D. W. Buxton, on con- 

 tractile tissue, etc. ; C. S. Sherrington on 

 the spinal cord of the dog ; E. F. Hcrroun 

 and G. F. Yeo, on " The Sound accompany- 

 ing the Single Contraction of Skeletal Mus- 

 cle " ; and transcripts from the Proceedings 

 of the Physiological Society, 1SS5. 



Revision of the Palj^ocrinoidea. Part 

 III. First Section. By Charles Wachs- 

 MUTH and Frank Springer. Philadel- 

 phia : William P. Kildare, Printer. Pp. 

 138, with Eight Plates. 



Hardly any kinds of fossils arc more 

 attractive to the collector than the crinoids, 

 with their endless variety of forms, each dis- 

 tinguished by its peculiar style of beauty and 

 grace ; and hardly any other kind offers a 

 richer reward to the searcher for specimens 

 who is so fortunate as to find a bed of them. 

 Since the first part of this work was pub- 

 lished, some five years ago, great progi'css 

 has been made in the study of both the re- 

 cent and fossil members of the order, and 

 many new and interesting forms have been 

 discovered and described. The authors of 

 the monograph confess that their own knowl- 

 edge of the subject also has grown. The 

 present section of the work includes a dis- 

 cussion of the classification and relations of 

 the Brachiate crinoids, with generic descrip- 

 tions. A second section is promised in the 

 " Proceedings of the Philadelphia Academy 

 of Natural Sciences" for 1886, to contain 

 the Articulata and Quadrinata. 



The PunLiSHED Whitings of Isaac Lea, 

 LL. D. By Newton Pratt Scudder. 

 Washington: Government Printing-of- 

 fice. Pp. 278. 



This is Bulletin No. 23 of the United 

 States National Museum, and is the second 

 of a series of bibliographies of American 

 naturalists which the Museum is publishing. 

 Dr. Lea is our oldest conchologist, and is 

 one of the most laborious and fruitful devo- 

 tees in that branch of research that our 

 country has had. He is still living, in his 

 ninety-fourth year, and blessed with good 

 health and unimpaired mental and physical 

 faculties. The list of his publications, as 

 given in this work, with full descriptions of 

 each, includes 279 titles. His cabinet of 

 Unionldce in Philadelphia displays about 

 ten thousand individuals, of different ages, 

 so arranged that each may be separately 

 examined, and it is unique in having many 

 species arranged with a sequence from the 

 youngest to the oldest, so that the student 

 may see at a glance the aspect of their 

 growth. 



Bulletin of the Sedalia Natural History 

 Society. Sedalia, Mo. No. 1, August, 

 1885. F. A. Sampson, Corresponding 

 Secretary. Pp. 30. 



The society was organized January 14, 

 1884, and has been able to report a year 

 and a half of successful operation. This 

 first number of its " Bulletin " contains its 

 constitution and by-laws, list of officers, and 

 acknowledgments of contributions ; together 

 with papers on the " Shells of Pettis Coun- 

 ty," by F. A. Sampson, and " Pettis County 

 Pcntremites," by Dr. G. Hambach, 



Bulletin of the Minnesota Academy op 

 Natural Sciences. Volume II. No. 5. 

 C. W. Hall, Secretary, Minneapolis, Minn. 

 Pp. 84. 



The present number of the " Bulletin " 

 includes papers from May, 1881, to Decem- 

 ber, 1882, the publication of which has be- 

 fore been unavoidably delayed. Among the 

 more important papers arc a report " On 

 Some Tests of Building-Stones," by J. A. 

 Dodge ; a report on the " Mineralogy of the 

 State, with Notes on the Bibliography of the 

 Subject," by N. H. Winchell ; and " Meteor- 

 ological Statistics of Minneapolis for Eight-
