PREFACE. 
Mrs. Loudon's Entertaining Naturalist has been so de- 
servedly popular that the publishers, in preparing a 
new edition, have striven to render it still more worthy 
of the reputation it has obtained. For this purpose, 
it has been # very thoroughly revised and enlarged by 
Mr. W. S. Dallas, Member of the Zoological Society, and 
Curator of the Museum of Natural History at York, 
and several illustrations have been added. 
In its present form, it is not only a complete Popular 
Natural History of an entertaining character, with an 
illustration of nearly every animal mentioned, but its 
instructive introductions on the Classification of Ani- 
mals adapt it well for use as an elementary Manual of 
the Natural History of the Animal Kingdom for the use 
of the Young.
