1856. He immediately entered the freshman class in Yale 

 College, pursuing the regular classical course, and receiving 

 the degree of B.A. in 1860. Graduate courses in the natural 

 sciences were continued in the Sheffield Scientific School during 

 the two years following (1861-62). The long summer vacations 

 from 1851 to 1862 were occupied in collecting minerals and 

 fossils from New York, New England, and Nova Scotia. To 

 the latter region he made five trips during this interval, and 

 obtained much valuable experience and scientific material. 

 On his second visit (1855) he found some fossil vertebrae in 

 the Coal Measures at South Joggins, representing a new and 

 important vertebrate animal {JEosaurus). This discovery 

 finally directed his studies into the channel which became his 

 life-work. At this time, however, his interests were about 

 equally divided between invertebrate paleontology and miner- 

 alogy, and it is worthy of note that his first scientific paper 

 was published in this Journal in 1861, under the title " The 

 Gold of Nova Scotia." 



The description of Eosaumis did not appear until 1862, 

 seven years after its discovery. Even then it cannot be said 

 that he had developed a strong liking for vertebrate paleon- 

 tology. This closes the account of his student life in American 

 schools. 



The next three years were passed in study abroad, in the 

 universities of Berlin, Heidelberg, and Breslau. He attended 

 lectures and took special courses with H. Rose, G. Rose, 

 Ehrenberg, Peters, Roemer, Grube, ' and Gceppert. The vaca- 

 tions were occupied, as before, by geological excursions. He 

 visited the most important localities in Europe, and obtained 

 extensive collections. His official connection with Yale Col- 

 lege began by his appointment, in 1866, to the chair of 

 Professor of Paleontology. This title he held in high esteem, 

 as it was the first established either in this country or else- 

 where. 



After attending the meeting of the American Association 

 for the Advancement of Science at Chicago, in 1868, Marsh 

 went as far west as Nebraska and Wyoming, along the route 

 of the Union Pacific railroad, then just opened. This trip 

 gave him a foretaste of the inexhaustible fossil riches of the
