NEW CONTRIBUTIONS ON THE HERRING-QUESTION, ETC. 211 



p. s. — We learn that, at the suggestion of Professor Mohn, the director 

 of the Norwegian Meteorological Institute, an expedition will this sum- ' 

 mer (1875) be fitted out for exploring the open North Sea between Nor- 

 way, Iceland, and the Farce Islands, to which Professor Sars will be 

 attached. We hope that this eminent naturalist will thus have a chance 

 to submit his theory to a test in that direction where we think that its 

 weakest point lies, viz, in the hitherto unknown. We heartily wish that 

 he may have the triumphant satisfaction to clear up every doubt, and 

 dissipate the last clouds of obscurity which envelop the natural history 

 of the Norwegian herring.
