414 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



este," Professor Claus lias edited the first part of a handsome 

 volume containing memoirs on the minute structure of the 

 Siphonophores, represented by the Portuguese man-of-war. 

 A paper on the male reproductive organs of the crabs, and 

 one on the origin of the vasrus nerve in the sharks, with 

 especial reference to the electrical batteries of the torpedo, 

 also appear in the part issued. 



Most excellent work was done in this country by Professor 

 W. K. Brooks and others, of the Johns-Hopkins University, 

 in a zoological laboratory established during the last sum- 

 mer at Old Point Comfort, Ya. Unfortunately, the work 

 done (regarding the development of Lingula and Amphiox- 

 us) remains unpublished for want of means on the part of the 

 university, as few, if any, would be found to purchase the 

 pamphlet or work containing the memoirs, owing to the 

 great lack of advanced students in this country like those 

 of Germany, who purchase such works at the expense of oth- 

 er luxuries. 



The Zoological Station of the Zoological Society of the 

 Netherlands has published its third report. The Station 

 during the summer of 1878 was erected on the island of 

 Terschelling, and in the course of two months it was visited 

 by ten zoologists for the purpose of studying the animals 

 of the Zuyder-Zee. 



The Zoological Garden in Philadelphia has been specially 

 favored. Its management has been in the hands of gentle- 

 men of the highest character and position, and the excep- 

 tionally large receipts coming to it during the Centennial 

 and preceding years have so assisted its rapid development 

 that what is usually the growth of many years has been ac- 

 complished by the Philadelphia society in a few months. 

 This garden was opened in July, 1874. Up to March 1, 

 1878, it had been visited by the large number of 1,508,501 

 persons, and its gate receipts amounted to 8226,301.70. Its 

 collection of animals is the finest in the country, and con- 

 sists of 434 mammals, 453 birds, 58 batrachians, and 63 rep- 

 tiles. The beauty of the grounds, the taste with which they 

 have been laid out, the elegance of the buildings (perhaps 

 too costly for their purposes), and the excellence of their col- 

 lection combine to make the Philadelphia Gardens compare 

 favorably with many of the long-established gardens of the
