between its canines before he begins to eat, waiting till it is quite 

 dead and quiet. In eating he never uses his canines at all, but 

 bites at the fish with the side of the mouth only. The molars 

 and the premolars are also very sharp, but capable of crushing 

 any substance into very small bits,"— a process which seems 

 necessary from the very small size of the gullet. 



We might cite other chapters in which the reader will find

 whose name while he lived had become quite "a household 

 word."

As a means of affording amusement, or as an aid to scientific 

 research, the use of the microscope is daily becoming more 

 general, and as a natural consequence the number and im- 

 portance of publications bearing on the subject are also daily 

 increasing. 



The manual, of which twelve parts are now before us, has 

 long since established itself as a valuable book of reference', and 

 no better testimony to its utility exists than the fact that' it is 

 now in a fourth edition. 



_ It may be briefly stated that the object of this work is to 

 guide the microscopist in his researches, to give him a notion 

 of the manner of making those researches, also some account of 

 the characters, microscopic structure, and properties of objects 

 in general, and to show how he may most easily arrive at 

 satisfactory results. 



Prefixed to the Dictionary is a long Introduction in which 

 useful hints are given as to the principles which should guide in 

 the selection of a microscope and the accessory apparatus ; and 

 this is by no means unimportant, because at the present dav a
