 This classification was published early in the present 

 year (1833), and has excited very considerable interest 

 among the learned men of France. Its author is M. Am- 

 pere, Member of the Academy of Sciences, and Professor 

 of Natural Philosophy in the College of France. The 

 Classification strikes us as exhibiting much . more of inge- 

 nuity in the author than of utility to the public. Of the 

 " carmen mnemonicum," prefixed to it, we think quite other- 

 wise. It is a synopsis, in Latin verse, of all the objects of 

 human knowledge ; and these are so pleasingly enumerated, 

 that a perusal must delight the student, as showing him the 

 objects which are presented in nature and in life for the 

 human mind to employ its capacity upon ; and, we think, 

 must, as well, fire him with the endeavour to extend his 

 mind to the comprehensive grasping of a knowledge of them 

 all. The poem deserves to be learned by heart, and so 

 rendered indeed a " carmen mnemonicum," or poem to be 

 remembered. Notwithstanding our indifference to the Ta- 

 bleau, or Classification, it is quite likely that it may be deemed 

 of much interest by those whose taste is more metaphysical 

 than our^Q-} j Uf j tjsoyb aid didferf ^Lriotlg JJ «tjiviO nolfil
