140 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



to that of the quaternary deposits of Norway was thought 

 to he quite noticeable; hut many of the characteristic North 

 European invertebrates were not met with. This may, per- 

 haps, have been owing to the comparatively limited extent 

 of the investigations. It was expected that quite a resem- 

 blanee would he found to exist between the recent fauna of 

 the deeper parts of the Gulf of St. Lawrence and that of the 

 post-pliocene deposits of Canada. This, however, was not 

 very striking, although scfmewhat indicated. 12 A 9 Novem-

EXPLORATIONS IX VINEYARD SOUND. 



Professor Verrill has lately given, in the Journal of Science, 

 an account of the researches in marine zoology prosecuted by 

 him during the past summer at Wood's Hole, Massachusetts, 

 in connection with investigations of Professor Baird respect- 

 ing the food fishes of the coast of the United States ; and in 

 this he calls the attention of geologists to some of the more 

 important features of these examinations, promising a fuller 

 account hereafter. One of these results consisted in ascer- 

 taining that, while the shores and shallow waters of the bays 

 and sounds, as far as Cape Cod, are occupied chiefly by south- 

 ern forms belonging to the Virginian fauna, the deeper chan- 

 nels and central parts of Long Island Sound, as far as Ston- 

 ington, Connecticut, are inhabited almost exclusively by north- 

 ern forms, or an extension of the Acadian fauna. Both the 

 temperature observations at the surface and the deep-sea 

 dredgings prove that there must be an offshoot of the arctic 

 current settling into the middle of Vineyard Sound. Quite 

 a number of interesting ascidians, both simple and compound, 

 were met with by Professor Verrill, several of them entirely 

 new to science. Several new sponges were collected, and 

 also a large number of crustaceans and mollusks previously 

 unrecorded in that region. We would refer our readers to 

 Professor Verrill's article in the November number of the 

 American Journal of Science for these interesting facts. 4

EXPLORATION OF THE GREAT LAKES. 



We have already referred occasionally to investigations 

 prosecuted during the past summer, on the great lakes, into
