AMOS H. WORTHEN. 
PALHONTOLOGIST AND GEOLOGIST. 
Born Octoser 81st, 1812; Diep May 6ru, 1888. 
Amos H. Wortuen, a son of the late Thomas Worthen, was born 
at Bradford, Orange County, Vermont. He commenced life as a 
Schoolmaster in Harrison County, Kentucky, but in June, 1836, 
he removed to Warsaw, Illinois, where he spent the remainder of 
his life. While engaged in business, he became interested in the 
science of Geology, and made a large collection of fossils, and also 
of those remarkable geodes of the Keokuk limestone in that region, 
On the institution of the Geological Survey of Illinois in 1851, 
under Prof. J. G. Norwood, he was appointed his Assistant, which 
post he filled for four years. From 1855 to 1857 he was Assistant 
to Professors James Hall and J. D. Whitney on the Geological Survey 
of Iowa, and the volume published in 1858 owes much of its value 
and interest to the labours of Mr. Worthen. The many beautiful 
plates of this large volume are from drawings by Mr. F. B. Meek, 
who was afterwards associated with Mr. Worthen in the paleontology 
of his own Reports. 
In March, 1858, Mr. Worthen was appointed by the State to the 
charge of the Geological Survey of Illinois, which position he 
occupied till 1872, when he became Curator of the Illinois State 
Museum. 
The seven completed volumes of the Geology and Paleontology 
of Illinois form the best and most lasting monument to his memory. 
Mr. Worthen left an eighth volume in the press. Besides these 
voluminous reports, he issued a large coloured geological map of 
Illinois, and three volumes on the Economical Geology of the State. 
He was also the means of gathering for the State Museum one of 
the largest and best collections of fossils in the country. 
In the early part of the Survey Mr. Worthen encountered and 
overcame great opposition. His modesty and earnestness, high 
character and quiet dignity, gave him great influence, and the many 
difficulties disappeared before him. Although nearly 75 years of 
age at his death, he had not given up work; the preparation of the 
text and plates illustrating the Silurian Invertebrate fossils of Illinois, 
for the eighth volume, was occupying him, when a sudden attack of 
pneumonia brought all to an end.— Silliman’s American Journal,
