234 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



Colorado, by Professor Cope, in which he presents the paral- 

 lelism of the formations recently investigated by him with 

 those earlier known and in other parts of the West. He con- 

 cludes that, although these formations have generally been 

 considered as tertiary, the geological evidence shows them 

 to be strictly mesozoic, as in the great lignite formations on 

 the Missouri River. 



During the past season twenty-one new species of verte- 

 brates were obtained in the pliocene sandstone at the head 

 of the water-shed between the South Platte River and the 

 Lodge-pole Creek. The most important result was, first, the 

 discovery that the camels of that period possessed a full se- 

 ries of upper incisor teeth ; second, that the horses, of the ge- 

 nus Protohippiis are, like those of Hipjjot/ierium, three-toed ; 

 third, that a mastodon of the 31. ohioticus type existed dur- 

 ing the same period. 



FINAL REPORT UPON THE GEOLOGY OF OHIO. 



We have already given a notice of the appearance of the 

 first volume of the final report upon the geology of Ohio, by 

 Professor Newberry, and we have now to chronicle the pub- 

 lication of the first volume of the series of reports on the pa- 

 leontology, a work of very great scientific value. It em- 

 braces three sections : first, a description of the invertebrate 

 fossils of the Silurian and Devonian system, by Professor F. 

 B. Meek ; second, descriptions of the fossil fishes, by Profess- 

 or Newberry; and, third, descriptions of fossil plants, also 

 by Professor Newberry. This volume is fully illustrated by 

 forty-eight plates, representing the new and more interesting- 

 species. As the first systematic account of the fossil re- 

 mains of the state, this volume has a special importance, 

 since, although descriptions of a large number of species have 

 been actually published, they are scattered through the trans- 

 actions of societies and scientific serials at home and abroad, 

 requiring a large library for their study. The concentration 

 of this information in the volumes of the report, with new de- 

 scriptions and figures, together with large numbers of new 

 species, brings the means of prosecuting such inquiries with- 

 in the reach of any one.

 tion, to some interesting points connected with the vertebrate
