end, the ninth lying on top of the eighth. The tenth and eleventh were also 

 interlocked. The twelfth presacral or last (fifteenth) cervical was considerably re- 

 moved from the succeeding dorsals and less so from the preceding cervicals. Com- 

 mencing with the next vertebra (cervical fourteen), the direction of the entire cervi- 

 cal series was altered so that it lay with its axis almost at right angles to that of the 

 dorsal series. The cervicals extended in an almost straight line from the fourteenth 

 to the fifth, but there was a considerable gap between cervicals eleven and ten, while 

 the axis and cervicals three, four and five were doubled back under the succeeding 

 vertebrge." 



"Of the remainder of the skeleton the bones secured were found in the same 

 relative positions as shown in the diagram (PI. L). Most of the ribs of the right side 

 were not shifted far from their original position in reference to the vertebral column. 

 The right femur was nearly in position, the left scapula and coracoid were shifted far 

 forward from their normal position and lay parallel with the cervical series. The 

 right pubis lay just in front of the ilium, parallel with the skeleton, with the 

 proximal end toward the ilium, while the left pubis* was found near the tenth 

 caudal and lay at right angles to the caudal series. The ischia lay side by side, 

 mingled with the ribs in the mid-dorsal region, while not far distant were the two 

 sternal plates." 



Throughout the excavations attending the disinterment of the above-mentioned 

 remains strong hopes were entertained that the entire skeleton would be recovered, 

 save only the posterior caudals, which, if ever imbedded with the other remains, had 

 evidently been entirely removed by recent surface erosion. Late in the autumn of 

 1 899 the work of excavating for the still missing portions was abandoned for the 

 season. During the latter part of April and first part of May, 1900, an additional 

 excavation was made by the present writer and a considerable area uncovered lying 

 immediately adjacent to that worked the previous season by Dr. Wortman. This 

 resulted in the discovery of portions of a second skeleton of Diplodocus. Early in 

 May the work of exhuming the remains of this second skeleton was entrusted to 

 Mr. W. H. Reed, who continued the work uninterruptedly until May 27th, when 

 Mr. 0. A. Peterson took charge, making extensive additional excavations. He con- 

 tinued the work throughout most of the season of 1900, assisted by Mr. C. W. 

 Gilmore and Mr. Wm. Patton. Notwithstanding the extensive excavations made 

 in 1900 in search of the missing portions of the skeleton discovered and taken 

 up by Dr. Wortman during the previous season, not a single bone was found in 

 these subsequent excavations, which can be said without doubt to pertain to that 

 skeleton.
