The past year has been characterized by the increased attention 
given to the anatomy of Birds. The remarkable attempt at a 
natural classification of the class by Prof. Sundevall, and the 
somewhat pretentious ^ Thesaurus ^ of Prof. Giebel, portions of 
which have appeared, will always render the ornithological 
literature of 1872 memorable, to say nothing of the commence- 
ment in India of a new journal, ^ Stray Feathers,^ solely devoted 
to the advancement of this branch of science.
