Miscellanies. 39]. 



A copious introduction (pages x to lx) treats : 



I. Of the use of the microscope and the examination of objects. 



II. Of the methods of determining structure from — «, the mi- 

 croscopic awaZys is of the surface, including — 1. the form ; 2. the 

 colour; 3. the structure ; and 4, the internal structure : h,\h.Q his- 

 tological analysis : c, the qualitative chemical composition : and <?, 

 the measurement. The body of the work is arranged alphabeti- 

 cally and each article has numerous Bibliographical citations in 

 which the student,is referred to the best and latest works, treating 

 on the specific subject. The authors have given a larger space to 

 Microscopic Botany than to any of the other departments of the 

 science. The plates are tolerably good, and the wood engravings 

 profuse and excellent. We cordially recommend the work as a 

 valuable vade-mecum to the general naturalist, who has not access 

 to an extensive scientific library. 



Drops of Water ; their marvellous and beautiful Inhabitants 

 displayed by the INIicroscope, (6 coloured plates; square 16mo; 

 price 7s 6d. ; London: Lovell Reeve,) is the title of an. elegant 

 and fascinating little volume by Miss Agnes Catlow, well adapted 

 to young folks. Her plates are copied without acknowledgement 

 by a United States writer, a Rev. Joseph Wythes, M.D., in a book 

 entitled " Curiosities of the Microscope." Any one claiming to 

 be a member of both learned professions ought to know better 

 than to act so dishonorable a part.

We cordially recommend these two admirable Monographs to 

 the students of Microsbopic Botany in Canada. They enter fully 

 into the Habits, ]N"ature, Structure, Reproduction, Classification, 

 Determination and Uses of the Families of which they respectively 

 treat ; and are written, descriptions and all, in the English lan- 

 eruaafe.
