Our especial thanks are due to the Council of the Royal 
Oollege of Surgeons for permission to use the woodcuts from 
their “Osteological” Catalogue; to Mr. Howard Saunders for the 
nndly help he has rendered during the progress of the volume

enough to send us some original notes on nests and eggs, which 
unfortunately reached us too late to be included in their en- 
tirety.
