398 Reminiscences of 



and Wyoming have resulted in the generaUzing of 

 diversified groups of aquatic mammals of earlier types 

 in the mixosaurus and shastasaurus class of reptiles, 

 distinctive links anterior to the life of the mammoth 

 fossilized saurian remains found in Colorado, to 

 be yet further detailed, from which the evolution 

 of the whale and kindred genera is readily traced, 

 as distinctively as that of the horse of the present 

 day from its five-toed ancestral type of inferior 

 size. 



Curiously interesting is the history of evolution, 

 yet but partially explained, but sufficiently to in- 

 dicate a great future advance, though probably never 

 to be fully illustrated.

 formerly a numerous and powerful one, is in late 

 years reduced to a few thousand. Comparatively 

 peaceful by the restrictions of government, they,

 which have an extensive sale. Many of these are of fine 

 texture, and often sell as high as $ 100 or more. They are
