204 Bibliographical Notices. 



that this Fasciculus well deserves to form a portion of the valuable 

 work with which it is connected. It contains plates and descriptions 

 of fourteen genera of Cruciferse, two of Papaveraceae and the genus 

 Caltha. These are illustrated in a rather more complete manner 

 than was adopted in the earlier parts of the work. 



Concerning the other two fasciculi mentioned above, it is hardly 

 necessary to say that they are creditable to the eminent men whose 

 names are associated with them. 



We cannot conclude without specially directing the attention of our 

 botanical readers to this work, as having the unusual properties of 

 cheapness combined with excellence. It is quite essential to every 

 student of European plants, and by far the greater number of the 

 genera illustrated in it are natives of Britain. 



The Microscope and its Application to Clinical Medicine. By 

 Lionel Beale, M.B. 8vo. pp. 282. 



The Microscope ; its History, Construction, and Applications. By 

 Jabez Hogg, M.R.C.S. 8vo. pp. 434. 



The former of these works, as is implied in its title, scarcely comes 

 within our range of subjects. Inasmuch, however, as it treats of the 

 method of using the microscope, the means of examining and pre- 

 serving objects, &c, we can recommend it as containing a tolerably 

 satisfactory account of the present state of knowledge upon these 

 subjects. It contains upwards of 200 woodcuts, and will form a 

 useful handbook to those members of the medical profession who 

 have not sufficient time to procure the information from the original 

 sources ; for it contains nothing new. We must . observe, that in 

 regard to the history, &c. of one or two points, it is in error. 



Mr. Hogg's book is of a different kind. It is intended for a 

 popular work, and forms one of the series of the " Illustrated London 

 Library." 



It may be said to consist of two parts : a series of quotations, in 

 brackets, from various authors, in regard to microscopy and natural 

 history, and a number of annotations, with poetical abstracts by the 

 author, and is illustrated with numerous woodcuts. The quotations 

 embody a considerable amount of information upon natural history 

 and microscopy, for there is about as much of one as of the other ; 

 whilst the remarks of the author exhibit complete ignorance of both 

 these subjects, as well as a total deficiency of classical lore. Moreover, 

 the whole is written in a remarkably loose and clumsy style, well 

 calculated to disgust an educated mind with the use of the microscope 

 and microscopic observers. 



Thus, we are told, that "the Eunotia is of the Navicula species." 

 That " the scientific name by which the yeast-plant is known is 

 Fermentum cervisice, or Torula cervisice." That " the leathery 

 boletus is merely an enormous aggregation of the vegetable mould- 

 plant or mueor." That " the disease known as ring-worm, in- 

 festing the heads of children, is one out of forty-eight different
