interests replacing the bodily social or polyp-stock or worm- 

 stock of the lower animals. 



The subject of Fetichism in Animals is treated, by Mr. G. 

 J. Romanes, in Nature^ who believes that a sense of the mys- 

 terious exists in dogs, and that it is this sense which is the 

 cause of the dread which many animals show of thunder. He 

 relates a number of interesting anecdotes bearing on this sub- 

 ject. 



Mr. Dall's Nomenclature in Zoology and Botany is a time- 

 ly series of rules comprised in a report to the American As- 

 sociation for the Advancement of Science. It was the result 

 of replies to a circular prepared by Mr. Dall, and sent to the 

 leading systematists in this country. It may be considered 

 as an authoritative code of rules, and should be followed as 

 closely as circumstances and good judgment will dictate. 

 With them should be read Professor Yerrill's edition of the 

 Rules of the British Association (American Journal of Sci- 



e?ice, July, 1869). 



Treatises. 



Among recent text-books on zoology, of value to the gen- 

 eral student, is Schmarda's " Zoology," published in 1878, and 

 beautifully illustrated with fresh wood-cuts. The introduc- 

 tory portion is especially valuable. Pagenstecher's "General 

 Zoology" is not so well illustrated, but, as its name implies, 

 is written from the side of general biology and comparative 

 anatomy. It is incomplete ; the third part is devoted wholly 

 to the subject of respiration in animals. By far the most 

 useful book, however, is the English translation of Gegen- 

 baur's "Elements of Comparative Anatomy," the most au- 

 thoritative German work. The style of treatment and the 

 introduction of speculative questions into anatomical descrip- 

 tions will be quite new to English-reading students. 



There has appeared an American edition, revised for use 

 in this country, of an excellent little treatise on the " Zoolo- 

 gy of Vertebrates," by Professor Macallister, of Dublin. 



Explorations* 



Mr. Agassiz has, during the winter of 1877-78, explored 

 the Yucatan Bank and other points, at great depths, with the 

 d red jre, aboard the United States Const Survey steamer JBlake. 

 lie discovered that the fauna of the Yucatan Bank is identical
