was right, but it was not until 1893 that the actual bones of one of the 

 reptiles were found in a sufficiently good state of preservation to allow 

 Prof. O. C. Marsh to make the restoration shown in fig. 123. This 

 particular form was about six feet in height, when standing, as in the 

 figure. '"One of the most slender and delicate dinosaurs yet dis- 

 covered, being only surpassed in this respect by some of the smaller, 

 bird-like forms of the Jurassic." The creature is shown in the figure 

 in the position it is thought to have habitually assumed. On a firm 

 but moist beach only three-toed impressions would have been left by 

 the hind feet and the tail would have been kept free from the ground. 

 On a soft muddy shore the claw of the fifth digit would have also left 

 its mark, and perhaps the tail would have dragged. When, perhaps 

 momentarily, he rested on his fore feet, tracks of a quite dissimilar 

 nature would have resulted, such as at first were assumed to be those 

 of an animal of another species. 



And so the matter rests. 



Dr. James Deane was born at Coleraine, .Massachusetts. February 

 21, 1801, and became by profession a physician, practicing at Green- 

 field, in the same State. Eminently successful in his practice, he 

 nevertheless found time for stud}' and work in other

 from the great labors of his profession. Late into 

 the night was his lamp seen glittering from his -casement * * * 

 while he was copying, with his masterly touch, these relics of an 

 ancient era" (Bowditch). He is described as a man of few words, 

 though of a genial and social character; of a tall and commanding- 

 form, and a well knit, compact frame: a man whose very walk con- 

 veyed an idea of strength.
