Xlviii PRELIMINARY SKETCH OF THE 



been published in France on this subject, 

 remarkable for the beauty of the illustra- 

 tions. Le Vaillant's work on the Birds of 

 Africa, contains many new species, and in- 

 teresting observations ; as do his works on 

 Parrots, Birds of Paradise, $c. In Germany, 

 ornithology has been much advanced by 

 Messrs. Wolf and Meyer, and the figures pub- 

 lished by Borkhausen,Lichthammer and Becker, 

 are possessed of merit. M. D'Azara, whose 

 excellent history of the quadrupeds of Para- 

 guay, we have already noticed, has given also, 

 in the two last volumes of his Travels in 

 South America, a history of the Birds of Pa- 

 raguay. 



Elegance of illustration, has been displayed 

 upon a class of animals, apparently but little 

 susceptible of its exhibition. Daudin in France, 

 has given, beautifully executed, figures of frogs, 

 toads, tyc, and our own countryman, Dr. Rus- 

 sel, has published the serpents of the coast of 

 Coromandel, with considerable magnificence of 

 style. 



Herpetology, or the study of reptiles, a 

 class of animals for a long time neglected, owes 

 much to the labours of Lacepede, Daudin, and 

 Schneider.
