The ' Educational Sheet of Butterflies ' ; " a cheap set of figures 

 of British Lepidoptera for the use of schools and beginners," 

 published also by Mr. Stainton, being another step in the popular 

 move, requires a notice, as the figures are well executed and 

 very characteristic. The method of teaching through the eye is 

 good, if the representations of objects are faithful, and the idea of 

 such good and cheap figures as are given by Mr. Stainton deserves 

 praise : in the sheet under consideration there are twenty-seven 

 figures of Lepidoptera for the small sum of twopence. 



Mr. Stainton's 'Manual of British Butterflies and Moths' is 

 likely to be a good and cheap assistant to any one studying 

 the Lepidoptera of these Islands. Such a work was much wanted, 

 and when completed will detail the author's views on the nomen- 

 clature of our species, which are somewhat at variance with those 

 of other authors who have treated on the Lepidoptera. 



The ' World of Insects,' by Mr. Douglas, is a work conceived in 

 the same spirit as those of Mr. Stainton, just noticed, and contains a 

 great variety of information on insects generally, conveyed in such a 

 pleasing and popular way as likely to make Entomology agreeable 

 to the world at large, and to induce many to look more deeply into 

 Entomology as a charming pursuit, capable of giving much mental 

 pleasure. 



Here should also be mentioned Mr. Shield's ' Practical Hints 

 respecting Moths and Butterflies, with Notices of their Localities ; ' 

 a little work full of information on the subject of the Lepidoptera, 

 and very useful to any one who wishes to become a good collector 

 of our butterflies and moths. 



In tlie same series of popular works, the ' Substitute ' also ranks : 

 it is a weekly paper, looking very like a continuation of the 

 * Intelligencer,' but by another editor, whose name has not transpired. 

 It is published professedly as a " substitute " for the ' Intelligencer,' 

 and will be discontinued when the latter paper again resumes its 

 place. It contains, like the ' Intelligencer,' much information on 

 the localities, habitats, &c. of British insects. 



Mr. Wollaston's ' Treatise on the Variation of Species, with 

 especial relerence to the Insecta,' is a work of no ordinary' merit.
