in the Cryptodontia and the Dicnyodontia, and by the 

 combined lacertian and crocodilian characters in the 

 Thecodontia and Sauropterygia." In the same work 

 he tells us that, " the Anoplotherium, in several im- 

 portant characters resembled the embryo Ruminant, 

 but retained throughout life those marks of adhesion 

 to a generalized mammalian type ;" and assures us 

 that he has " never omitted a proper opportunity for 

 impressing the results of observations showing the 

 more generalized structures of extinct as compared 

 with the more specialized forms of recent animals." 

 Modern paleontologists have discovered hundreds of 

 examples of these more generalized or ancestral types. 

 In the time of Cuvier, the Ruminants and the Pachy- 

 derms were looked upon as two of the most distinct 

 orders of animals ; but it is now demonstrated that 

 there once existed a variety of genera and species, 

 connecting by almost imperceptible grades such widely 

 different animals as the pig and the camel. Among 

 living quadrupeds we can scarcely find a more isolated 

 group than the genus Equus, comprising the horses, 

 asses, and Zebras ; but through many species of Palo- 

 plotherium, Hippotherium, and Hipparion, and numbers 

 of extinct forms of Equus found in Europe, India, and 

 America, an almost complete transition is established 

 with the Eocene Anoplotherium and Paleotherium, 

 which are also generalized or ancestral types of the 

 Tapir and Rhinoceros. The recent researches of M. 

 Gaudry in Greece have furnished much new evidence 

 of the same character. In the Miocene beds of Pikermi
