THE HAEMONIES OF MTUEE; 



OR, THE UNITY OF CREATION. 



'DE.HAKTWiGhasproiluicd another 

 delightf 1 and instructive vokime, in 

 which he illustrates the wonders of 

 wisdom and knowledge with which 

 creation teems. The opeiii i ig chapters 

 are devoted to a recapitulation of some 

 of the magniflcent and astonishing 

 phfenomena which are observed in the 

 heavens, air, and sea, by way of de- 

 veloping the harmony which is the 

 universal law of nature. But through- 

 out thi- greater part of the work the 

 Authoreonlincs himself to the domains 

 of vegetable and animal life ; and here 

 he accumulates a surprising number 

 of evidences of design, adaptation of 

 power, and inexhaustible resource. 

 The work exhibits a very unusual and 



most felicitous combination of accurate 

 and varied erudition with clear and 

 pojHilar writing. It is a true in- 

 structor; for both the descriptions 

 and the woodcuts with which they 

 are accompanied are scientifically cor- 

 rect, while the narration is full of 

 almost romantic interest. Each page 

 has some new wonder to enchant the 

 youthful reader and excite the re- 

 verent admiration of the thoughtful. 

 . . . The reverence and piety of Dr. 

 Hartwig's works are a great recom- 

 mendatiou in days when scientific men 

 seem to tliink their first duty in speak- 

 ing or writing is to avoid every word 

 that could possibly suggest the idea 

 of a personal Deity and intelligent 

 Creator.' Pateiot.

' This is the third edition, consi 



derably enlarged, of the first and best 

 of Dr. Hartwig's beautiful and popu- 

 lar volumes on natural history. The 

 size of the book is increased by a 

 hiuidred pages ; a good deal of it is 

 remoulded ; two whole new chapters 

 have neeu added, one on Marine Caves, 

 the other ou Marine Constructions, 

 such as Lighthouses and Breakwaters; 



some of the old illustrations have dis- 

 appeared, but their place has been 

 supplied by more and better; so that 

 the new edition really amounts to a 

 recasting of the entire book. It was a 

 very good bonk before; it is better and 

 more complete now. AVhether we re- 

 gard the letterpress or the numerous 

 illustrations, it takes a rank second to 

 none among ornamental and popular 

 books of science.' Guardian.
