PREFACE TO NEW EDITION xix 
to Professor H. F. Osborn, who supplied photographs reproduced 
in Plates XV., XVI. and XX. Plate XXVI. shows a new and 
probably better restoration of Stegosaurus, by Mr. J. Smit. 
With regard to the Triceratops (the restoration of which is 
unusually difficult on account of the want of any single complete 
skeleton), a new attempt has been made by our friend Mr. J. 
Smit, based on the recently mounted and restored skeleton in 
the Natural History Museum, see Plates XXVII. and XXVIII. 
It was certainly a most strange beast, and we can only hope that 
in time every bone will be completely known. The now well- 
known Diplodocus has also been restored by the same artist from 
the cast in the Museum, see Plate XXII. Another comparatively 
new Dinosaur is the remarkable Polacanthus, seen in Fig. 60, 
reproduced by permission of Baron Nopcsa and Dr. Henry 
Woodward, F.R.S. 
Some new matter and illustrations dealing with sea-serpents 
will be found in Chapter X. 
The huge flying reptile or Pterodactyl Pteranodon, seen 
in Plate XXXIII, is from an illustration supplied by the 
Smithsonian Institution, U.S.A. 
With regard to birds, some new matter has been added, and 
a restoration of the great Patagonian bird Phororhacos, kindly 
lent by Professor F. A. Lucas of the Brooklyn Museum, who also 
lent the picture of the Mammoth seen in Plate XLIX. Mr. 
W. P. Pycraft also kindly lent his own restoration of the oldest 
known bird, the Archeopteryx, seen in Fig. 79, for which the 
author is much obliged, as it seems to be the only reliable 
restoration yet published. The truly wonderful story: of the 
evolution of the elephant can now be read in outline from the 
record of the rocks. This is certainly a result of which geologists 
may be proud. The drawings seen in Fig. 105 have been specially
