" This species is extremely common in the northern seas, and 

 forms the principal food of the cetaceous animals. In 1811, dur- 

 ing a tour made by me to the Orkneys with some friends, I ob- 

 served on the rocks on that side of the Isle of StafFa, several muti- 

 lated specimens of this animal ; the three previous days had been 

 extremely stormy, so as to confine us to the Isle Colunsa. Some 

 days afterwards I borrowed from a fisherman a large shrimp-net ; 

 and on rowing along the coast of Mull, when the sea was calm, 

 after many vain efforts I was at last enabled to capture one of 

 them alive. This specimen is in tliat part of the Zoological Col- 

 lection which I presented to the British Museum." 



The work from which the above extract is taken, and which 

 appeared just as the last sheet of our last number was passing- 

 through the press, demands from us more than a passing notice. 

 To a synonymy already overburthened, it adds an awful accumu- 

 lation of names, which, although invented by Dr. Leach, more than 

 thirty years ago. can only take date from December 1 852, the year 

 in which they are published, with descriptions attached. Mr. Gray 

 sends forth this work as an act of duty and justice towards his dis- 

 tinguished friend and master. There will be many doubts in the 

 minds of naturalists as to the good policy of the act, and whether 

 it can be regarded as one of either justice to Leach, or justice to 

 science. The eminent author of the manuscripts thus issued was, 

 unquestionably, a man of brilliant genius, and, in many respects, 

 in advance of his time. It would be unfair to judge of his merits 

 by this " Synopsis of the Mollusca of Great Britain," a portion 

 only of which appears to have been revised for the press. It is 

 scarcely fair to send forth these undigested pages, containing such 

 manifest experiments on the constitution of generic groups, that
