The five vessels of the squadron, under the command of Commodore Wilkes, sailed in August, 
1838, on a voyage around the world. After extensive explorations, dnd suffering shipwreck more¬ 
over at the mouth of the Columbia River in, Gregory Mr, Dana returned home in June, 1842. The 
rare opportunities which this voyage afforded for scientific observation'had been'well improved. 
During the thirteen years after its termination, he 1 was engaged in preparing for publication the 
various reports of this Expedition committed to his.charge, and in pursuing other scientific labours. 
He resided at Washington from 1842 to 1844,'and then returned to New Haven, Connecticut, 
where he soon after married Henrietta Frances, third daughter of Professor Benjamin Silliman, 
and where he has since resided. 
Before going to the Pacific, he published, in 1837, the first edition of his Mineralogy, a work of 
high repute in Europe and America, of which the fourth and last edition appeared in 1854. 
His first publication connected with his observations in the Exploring Expedition was a Report 
on Zoophytes, which appeared in 1846, a 4to volume of 740 pages, with an Atlas of 61 folio plates. 
In this work, Mr. Dana reviewed the whole department of Polyps, combining his own observations 
•with those of earlier authors, and proposed a new classification, bringing, for the first time, the 
Actiniae and the Alcyonoid Polyps into their true relations to the Astraeoid Polyps. The number 
of new species which he describes is two hundred and thirty. 
The second work in the same series, was a Report on the Geology of the Pacific, published in 
1849, a 4to vol. of 75.6 pages, with an Atlas of 21 Plates. This work presents a view not only of 
the geology of parts of Australia, Western America; and the islands of the Pacific, but also treats 
at length, and with original views, of Volcanic phenomena, Coral Reefs and Islands, and the 
General Features ef the Globe. 
The third work, pertaining to this Government Exploring Expedition, was a Report on Crustacea, 
which appeared in 1852-1854, the text 1620 pages 4td, the Atlas 96 Plates in folio. Six hundred 
and eighty species are described in this work, of which six hundred and fifty-eight are new. The 
subjects of Classification and Geographical Distribution receive in it special attention. These Re¬ 
ports were published by the Government of the United States, and only 200 copies of each have 
thus far been issued. With few exceptions, the drawings in these atlases were made by- Mr. 
Dana himself. 
While engaged in preparing the last two of these reports, Mr. Dana has been the active Editor 
of the American Journal of Science and Arts, founded in 1819, by Professor Silliman, sen., and 
well known as the great repository of the scientific labours of their countrymen. To this Journal 
which reached ; its seventy-third . volume in 1857, as well as to the Proceedings of the American 
Academy of Arts and Sciences in Boston, the ; Lyceum of Natural History of New York, and the 
Academy of Natural Sciences of Philadelphia, Mr. Dana has contributed various important 
memoirs. 
Soon after the resignation by Professor Silliman of the Chair of Chemistry and Geology in Yale 
College, Mr. Dana entered, in 1855, on the duties of the office of Silliman Professor of Natural 
History and Geology in that Institution, to which place he had been elected in 1850, his brother- 
in-law, Professor Benjamin Silliman, jun., having been appointed to the Chair of Chemistry. In 
discharging the duties of his professorship and in editing the American Journal of Science, Pro- 
fessor Dana is now engaged. 
In 1854 he was elected President of the American Association for the Advancement of Science, 
having been for many years one of the Standing Committee of that -body, and in August, 1855, he 
delivered the Annual Address before.that Association at its meeting in Providence. 
Professor Dana’s contributions to science evince uncommon skill in observation and great in¬ 
dustry, united to a high order of genius. They are probably unsurpassed in extent and value by 
those of any American philosopher.
