Life of David Dale Owen, M. D. 71 
ernor Conway made every effort, and succeeded, in sending 
safely several thousand dollars due from the appropriation, 
and required for the publication of fhe second volume, a duty 
undertaken by Prof. Richard Owen, as administrator at the 
request of the family of Dr. D. D. Owen, he having dictated por- 
tions of his report up to within two or three days of his death 
and having given full instructions regarding the details of 
publication. The chemical assistant in this survey was Dr. 
Elderhorst, author of a Avork on the blowpipe, a former grad- 
uate of VanRensselaer Institute, Troy, N. Y. 
7. In 1859 Dr. D. D. Owen accepted the appointment, a 
second time offered him, of state geologist of Indiana, with the 
understanding that the work should be executed by his 
brother, Dr. Richard Owen, who had then, in view of the im- 
pending crisis, resigned his professorship at Nashville. Tenn. 
The results of these two years' survey were embodied in a 
report comprising 368 8vo pages, with wood-cuts, diagrams, 
etc., by Dr. Richard Owen, who after his brother's decease had 
been appointed state geologist. The last of this report was 
read by him in camp, he having entered the federal service as 
lieutenant-colonel of the 15th Indiana volunteers. The 
assistants in this survey were Prof. Leo Lesquereux, for field 
examination, and Dr. Robt. Peter, for laboratory work. 
Personal characteristics, death, family left. 
A remarkably prominent feature in Dr. Owen's lifework was 
his indefatigable perseverance, even under great difficulties. 
While on the Red river of the North with a Canadian voyageur, 
the latter permitted his fowling piece, used for procuring 
game, to be discharged in such a manner as to lodge a number 
ofshotinDr. Owen's shoulder. But he did not permit the 
accident to delay him an hour. Again, although he found the 
Arkansas summer surveys, often made in the rich malarial 
bottoms, highly detrimental to health, bringing him home in 
the autumn with a hue denoting strong malarial derangement 
of the liver, he not only persevered in the surveys, but 
continued his laboratory winter work usually until midnight ; 
and, as remarked above, while suffering acutely during his 
last illnes8,dictated the closing portions of his Arkansas report 
until within 48 hours of his death. His skill as an artist 
enabled him, besides leaving some good portraits in oil of 
members of his family, richly to illustrate his reports. He
