lv PREFACE, 
book by Mr. R. 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 will 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 iong been famous. 
The Guide-book is completed by an appendix on the 
structure of Birds, with illustrations of the feathers and 
skeleton.
