4. EPISODES OF INSECT LIFE. 
““ We have seldom been in company with so entertaining a guide to the Insect World. 
Few merrier or wiser companions could be summoned to our firesides.’—Atheneum. 
‘“The letterpress is interspersed with vignettes cleverly engraved on stone. Alto- 
gether the book is a curious and interesting one—quaint and cleyer, genial and well- 
informed.”’—Morning Chronicle. 
“This beautiful volume—without exaggeration beautiful in typography, binding, 
illustrations, subject, and execution—should be the most popular, as it is the best, 
Gift-book of the season. It is Entomology made not only easy, but attractive and 
amusing. The writer has thorough scientific and practical knowledge, a love of his 
subject, and a style exceedingly suitable in its quietness and refinement. A vein of 
tender feeling and of natural piety is pleasingly mixed with a quiet and kmdly humour, 
never misplaced nor misapplied. ‘The design is greatly aided by numerous illus- 
trations well executed on stone, and finely and faithfully coloured.’’—Scotsman. 
‘* Our readers will find in this work the lively and the severe admirably blended ; 
rich veins of humour in a groundwork of solid, and yet entertaming information. 
Although lightness and amusement can find subject-matter in every page, the under 
current of the Episodes is substance and accurate information.’’— Pictorial Times. 
‘“‘ The style of these Episodes is after the manner of the Thackeray and Dickens class 
of works. It is in every way a wonderful book.”—North British Mail. 
‘¢ Professor Nichol has done much to make astronomy a lightsome science; Mr. 
Miller has gone down among the substrata of the island, and thrown the influence of 
eloquent and powerful writing around the fossils of the old red-sandstone ; but neither 
of them has, however, produced a work equal in the particular above mentioned to 
these Episodes,” —Taits’ Edinburgh Magazine. |
