BIRDS OF OLD 89 
For scientific descriptions of these birds the reader is 
referred to Owen’s paper “On the Archaeopteryx of von 
Meyer, with a Description of the Fossil Remains, etc.,” m 
the “Transactions of the Philosophical Society of London 
for 1863,” page 33, and “ Odontornithes, a Monograph 
of the Extinct Toothed Birds of North America,” by O. 
C. Marsh. Much popular and scientific information 
concerning the early birds is to be found in Newton's 
“ Dictionary of Birds,” and “ The Story of Bird Life,” 
by W. P. Pycraft ; the “ Structure and Life of Birds,” 
by F. W. Headley; “ The Story of the Birds,” by J. 
Newton Baskett.
