DAVID DALE OWEN. 503 



the classes in physics and chemistry conducted by Dr. Andrew 

 Ure, author of the Dictionary of Arts, Manufactures, and 

 Mines, at Glasgow, where their mother then resided. Their 

 father was absent at New Harmony. For that place the two 

 younger sons set out in November, 1827, going by a ship 

 from Liverpool to New Orleans, thence up the Mississippi by 

 steamer, reaching the settlement on the Wabash early in Janu- 

 ary, 1828. 



During the next three years they kept up and increased 

 their knowledge of chemistry by repeating the experiments 

 of Dr. Ure's course. Desiring to extend his knowledge of 

 chemistry and geology, Dale Owen in 1831 returned to Great 

 Britain. He had as a companion Henry D. Rogers, and they 

 both lived at the house of Owen's father in London while 

 attending the lectures of Dr. Turner at the London Uni- 

 versity. 



After about a year abroad Owen came back to the United 

 States. Soon after his return he was stricken with Asiatic 

 cholera, which was epidemic in this country in the summer 

 and fall of 1832, but was fortunate enough to survive the 

 attack. Wishing to increase his knowledge of anatomy and 

 physiology as an aid in the study of paleontology, he entered 

 the Ohio Medical College, in Cincinnati, and was graduated 

 in the spring of 1836. He devoted the summer following his 

 graduation to gaining practical experience in field geology. 

 To this end he accompanied at his own expense Dr. Gerard 

 Troost, who was then engaged on the State Survey of Ten- 

 nessee. 



Dr. Owen married, March 23, 1837, Caroline C. Neef, the 

 third daughter of Joseph Neef. 



Having been appointed State Geologist of Indiana, Dr. 

 Owen, immediately after his marriage, entered upon the duties 

 of this position. He made a preliminary reconnaissance in 

 1837 and 1838, his report upon which was published immedi- 

 ately after its completion and reissued in 1859. Geological 

 science being little understood in the West when this document 

 first appeared, a brief introductory exposition of the leading 

 formations was given in it, after which the rich deposits of 

 coal, iron, and building stones within the limits of the State 

 were described.
