opportunities for extending their area of experience, throughout 

 the domain of marine biology. As an advance upon these less 

 pretentious marine laboratories, have been evolved those more 

 perfectly appointed institutions, such as the Zoological Station 

 at N^aples, or the more recently erected Marine Biological 

 Station at Plymouth. The Xaples station, founded by Dr. 

 Dihrn, has been established for the more exclusive object of 

 purely scientific research, and is resorted to for this purpose by 

 scientists from every country in Europe. Oxford University, 

 among others, pays, or until recently paid, a subsidy to Dr. 

 Dohrn, for the privileges of having a " table " at his station 

 reserved for the use of her students and graduates, while the 

 same institution has been in receipt of a yearly grant of £100 from 

 the British Association for the Advancement of Science, to assist 

 towards the furtherance of its exclusively scientific aims. The 

 University of Pennsylvania, in the United States, also holds a 

 table at this Marine Z )ological Stition, on the same t^ran as 

 that of Oxford. 



At the more recently established British Zoological Stations 

 and Marine Laboratories, and likewise at those in America, a 

 more practical element has been introduced. In addition to the 

 i*esearches connected with organisms of purely scientific import 

 much attention has been given to acquiring a knowledge of the 

 embryology, life habits, and general economy of all fish, and 

 other marine products having a direct economic value. At the 

 Scottish Marine Biological Laboratory, associated with the Edin- 

 burgh University, by way of example, most valuable investiga- 

 tions have been conducted by Professor Cossar Ewart and others, 

 with relation to the spawning habits of the common herring, and 

 both here and at the Plymouth station, the turbot, sole, lobster, 

 oysters, and other commercial products of the sea. have been 

 subjected to scientific investigation with the object of solving the 

 many problems associated with their reproduction, and with the 

 object of increasing their rates and areas of distribution by 

 ai'tificial means. The progress made in the science of fish propa- 

 gation, through the instrumentality of seaside and riverine Inbo-
