young Dana was attached made a narrow escape. He then visited 
in succession Chili and Peru, and subsequently crossed the Pacific, 
touching at the Paumotus, Tahiti, and the Navigator Islands, on 
his way to New South Wales and New Zealand. From New 
Zealand the voyage was resumed to the Fiji Islands, the Sandwich 
Islands, the Kingsmill Group, the Caroline Islands, and thence 
north to the coast of Oregon, where Dana’s ship was finally 
wrecked. He then accompanied the party that crossed the moun- 
tains and passed down the Sacramento Yalley to San Francisco. 
Here the wanderers again set sail, and made their way home by 
the Sandwich Islands, Singapore, the Cape of Good Hope, and St 
Helena, arriving at New York on 10th June 1842. It is needless 
to say that the experiences of these four eventful years made a 
profound impression upon Dana, and influenced all his subsequent 
life. For the next thirteen years he was fully occupied in study- 
ing the materials brought home by the Expedition, and in prepar- 
ing his reports. His geological observations are contained in a 
large quarto of 746 pages, accompanied by a folio atlas of 21 plates 
(1849). Besides this great work, he prepared a Report on Zoo- 
phytes of similar extent, with an illustrative atlas of 61 plates 
(1846), and a Report on Crustacea , which occupies 1620 pages, and is 
accompanied by an atlas of 96 plates (1854). Nor were his energies 
during this period confined to the elaboration of these reports, 
for we find him at the same time issuing three successive editions 
of the System of Mineralogy (1844, 1850, 1854), and two editions 
of the Manual of Mineralogy (1848, 1857), besides many papers 
communicated to various scientific journals. Not a few of 
these appeared in the , American Journal of Science , of which, 
in 1846, Dana had been made an editor, associated with Prof. 
Silliman, whose assistant he had been in 1836-37, and whose 
daughter he had married in 1842. In 1850 he was appointed 
to the chair of Natural History in Yale College — the title 
of the chair being subsequently changed to that of Geology and 
Mineralogy. 
The enormous amount of work accomplished in the few years 
after Dana’s return from abroad testifies to his abounding zeal and 
enthusiasm. Unfortunately, as his son Prof. E. D. Dana remarks, 
“ he was but little restrained by the thought that injury to health
