tion that legs or disks appear on this segment requires to be received, 

 or rather to be scutinized, with the greatest caution. It is somewhat 

 remarkable that two only of the figures of larvae represent them in a 

 position to exhibit these anomalously placed legs or disks : these are 

 the larvae of plagicolella and septembrella, figs. 1 and 2 of Plate IV., 

 and it is still more remarkable that these figures tally with my pre- 

 viously conceived opinion, and are at variance with Mr. Stainton's 

 description: in both instances the fifth segment is represented as 

 totally devoid of all appendages. The late William Wing — and it 

 always gives me a melancholy pleasure to mention the name of that 

 painstaking and amiable naturalist — was too accurate to have made 

 an error in these instances, so that I cannot avoid the conclusion that 

 Mr. Stainton's diagnosis requires revision. 



In conclusion, I may sincerely say that, willing as I am to point out 

 error, real or supposed, — to mention faults that I conceive to be suscep- 

 tible of improvement, — I consider this first volume of the ' Natural 

 History of the Tineina' to be a most valuable and praiseworthy pro- 

 duction, and that its author is deserving of our warmest thanks. 



' The Microscope, and its application to Vegetable Anatomy and 

 Physiology? By Dr. Hermann Schacht. Edited by Frederick

 Numerous Illustrations. London: Highley, Fleet Street. 1855. 

 Fcap. 8vo, 202 pp. letter-press, 130 woodcuts. 



We spoke so favourably of the first edition of this work that it were 

 needless repetition to express a second time our opinion in its favour. 

 The editor shall himself describe the difference between the second 

 edition and the first. 



" The rapid sale of the first edition of this translation has rendered 

 a second necessary ; and I wish to direct attention very briefly to the 

 points in which the present edition differs from the preceding. Four 

 chapters have been added at the beginning of the book; the first of 

 which relates to some elementary principles of Optics essential to a 

 proper comprehension of the Microscope; the second contains a 

 description of different kinds of English Microscopes, including, as 

 far as is necessary, the details of their different parts ; the third con- 

 tains an account of the accessory apparatus and chemical re-agents 

 necessary for microscopical investigations in Botany ; and the fourth 

 relates to the preservation of specimens. 1 have myself added these 

 Chapters, with a view of rendering the work more complete as a
