book by Mr. li. B. Lodge. The plates have been produced 

 from photographs of the actual specimens in the gallery : it 

 must be borne in mind that there are special difficulties in 

 photographing specimens which cannot be brought into chosen 

 conditions of light. Many of the illustrations vpill be found 

 to furnish a valuable record of the successful efforts to exhibit 

 birds in their natural surroundings, for which the Bird Gallery 

 of this Museum has long been famous. 



The Guide-book is completed by an appendix on the 

 structure of Birds, with illustrations of the feathers and 

 skeleton.
