speculation. There is much of the poet in him. All that is 

 spirit-stirring must proceed from the last two faculties of 

 mind : but, perhaps, in no branch of human knowledge is there 

 more need that they be strongly reined than in natural his- 

 tory. The fault of Mr. Mudie's present work may be, that 

 he therein has not reined them sufficiently. A profound 

 ornithologist has advised that the author certainly has not, in 

 his remarks on the wind-resisting powers of the plumage of 

 the mountain eagle.

 of all the known species of Infusoria; with instructions for

We are very glad to see this work. It is, or at least we 

 presume that it is, a clear indication of the latest state of the 

 knowledge of animalcules which has been attained in Britain. 

 There are six plates crowded with figures of these creatures, 

 whose forms are very varied, and those of some of them are 

 very extraordinary. The exhibited species, and many more 

 besides, are described generically and specifically, and " in 

 good set terms," in the text of the book ; where their system- 

 atic affinities, correlations of structure, &c., are treated of. 

 The classifications followed in the general arrangement are 

 derived from those by MUller and Ehrenberg. The last- 

 named author's arrangement of the Phytozoa is given, dis- 

 tinctly, towards the end of the book ; and to it are appended 

 some remarks by Mr. Pritchard, who observes, at the close, 

 that, " In a supplementary treatise, it is purposed to give a 

 more enlarged systematic arrangement of the Phytoz5a, ac- 

 cording to their organisation, together with the result of such 

 further observations as the author shall make or be favoured 

 with." A plate, exhibiting Pritchard's achromatic micro- 

 scope in different modes of adjustment, is prefixed to the 

 volume.

An interesting and superior work, richly deserving the 

 patronage of wealthy naturalists. Its foremost features are 

 botanical ; but with them are associated those of the geology,
