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.E.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 Archseopteryx, 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
