and a brig, the Oregon, was purchased to take the place of the 

 Peacock. The squadron returned to the Hawaiian Islands for 

 supplies. After some study of the Kuroshiwo, or Japanese 

 Current, the expedition made a short visit to the Philippine 

 Islands, then proceeded to Singapore, and returned home by way 

 of the Cape of Good Hope, visiting on the way Cape Town and 

 Saint Helena. The arrival at New York was in June, 1842. 



In the next few years Dana's task was the preparation of reports 

 of the scientific work of the expedition. He had undertaken, in 

 the first organization of the scientific staff, the mineralogy and 

 geology; but, in consequence of the retirement of one of the party 

 at the beginning, and of another during the course of the expedi- 

 tion, he was led to undertake also two parts of the zoology, viz., 

 the study of the Crustacea and that of the corals. The report on 

 Zoophytes appeared in 1846, that on Geology in 1849, the first 

 part of the report on Crustacea in 1852, and the remainder in 

 1854. The reports were issued in magnificent style, that on 

 Crustacea forming two great quarto volumes, the others each one 

 volume, and each report being accompanied by a folio atlas. It 

 is, however, only in a very accommodated sense of the word that 

 the scientific reports of the expedition can be said to have been 

 published. The number of copies authorized by Congress to be 

 printed was so small that they have been from the beginning 

 inaccessible to most of the students who would have profited by 

 their use, only a very few of the largest libraries possessing com- 

 plete or nearly complete sets. This absurd policy contrasts 

 strongly with the enlightened liberality with which the more recent 

 scientific publications of the United States government have been 

 distributed. For about two years after the return of the expedi- 

 tion, Dana worked in Washington, but in 1844 he returned to 

 New Haven, where he resided until his death. 



He married, June 5, 1844, Henrietta Silliman, a daughter of his 

 teacher and friend, Benjamin Silliman. The home life of more 

 than half a century which thus began was most happy. Mrs. 

 Dana and four children survived him. The oldest son, Professor 

 Edward Salisbury Dana, of Yale University, is a distinguished
