PREFACE TO SECOND EDITION 
The appearance of a second edition affords the author a pleasant 
opportunity of thanking the reading public, and the Press, for 
the kind way in which his endeavour to popularise the results 
of modern Palseontology has been received. There seem to be 
fashions in all things — even in sciences ; and perhaps the 
wonderful advances we have witnessed of late years in the 
physical sciences on the one hand, and in biological sciences on 
the other, may have tended to throw Palseontology somewhat 
into the shade. Let us hope that it will not remain there long. 
A large number of illustrations have been added for the 
present edition, besides additional matter here and there in the 
text. Three of the plates have been redrawn. Plate IV. shows 
the Ichthyosaurus as interpreted by the latest discovery from 
Wiirtemberg. 
Plate XXXVII., besides containing a valuable portrait of the 
late Sir Eichard Owen, gives another drawing of the Dinornis 
skeleton. 
April, 1893. 
The numbers of the Plates are those of the present Edition (1910).
