skeleton of a crested dinosaur, which he names Corythosaurus 

 casiiarius. In this skeleton not only is the skin impression 

 preserved, but the impression of the muscles and the animal's 

 pose, as if in the act of swimming. It has a beautiful head 

 on a long, swan-like neck, a huge body, and a long, eel-like 

 tail. Deckert, in an ideal picture, has simply put one in his 

 native element with the exact pose in which he died. I claim, 

 however, that he overreaches the evidence when he stands two 

 other forms on their hind limbs and tail, in the same picture, 

 I will not go so far as to say that it is impossible for the 

 creature to rise on his hind limbs ; however, I do claim that it 

 is an unusual position. I hope some day to see preparators 

 put these creatures down on mother earth, or in the water, 

 where they belong. When the creator shows us such wonder- 

 ful specimens which absolutely contradict the preconceived 

 opinions of men, whom should we follow? 



Among the horned dinosaurs, George F. Sternberg and my- 

 self each found a skeleton of a very beautiful form, much 

 smaller than the Triceratops of a later day. Mr. Lambe gives 

 the new generic name of Chasamosaurus , due to the great 

 openings in the crest. Mr. Brown, however, retains the name 

 Ceratops, which Marsh gave to his Judith river species on 

 which the family Ceratopsia is founded. In George's speci- 

 men we have the most perfect one of a horned dinosaur 

 with which I am familiar. It is over five feet long, with 

 great openings in the crest, the central bar thick in the cen- 

 ter and beveled to a thin margin, the cross bone behind at 

 right angles to it. I now know this bone is distinct from 

 the skull, although it has always been called parietal. It is 

 deeply notched in the median line. Powerful jaws hold maga- 

 zines containing over two thousand teeth in three parallel 

 rows, their grinding surfaces beveled above and below a pair 

 of scissors, with which to shred their food after it is nipped 

 off by the broad duck bill in front. The skin impression, too, 

 is distinct from what has been claimed. There are pictures 

 extant covering the thick, rhinoceroslike skin with heavy 

 dermal scutes, a necessary protection imagined by men who 

 neither knew the habit or the environment of the animal 

 they recreated from a few^ scattered bones. In my speci- 

 men I secured many examples of the skin impression, proving 

 it to be thin, clad in small scales, arranged like mosaic
