JOHN STRONG NEWBERRY, M. D., LL. D. 
CONTRIBUTIONS TO FOSSIL BOTANY. 
Dr. Newberry was born in Windsor, Conn., December 22, 1822, and 
died in New Haven, Conn., December 7, 1892. 
His earliest published scientific papers bear the date of 1851, and in 
1853 the first of his contributions upon the subject of fossil botany was 
published. This bears the title ‘Fossil plants from the Ohio coal basin,” 
and was published in the Annals of Science, Vol. I, Nos. 8 and 9 (Cleve- 
land, Ohio, 1853), pp. 95-97, 106-108. During the same year he read 
papers before the American Association for the Advancement of Science 
“On the structure and affinities of certain fossil plants of the Carboniferous 
era” and “On the Carboniferous flora of Ohio, with descriptions of fitty 
new species of fossil plants.” 
His next important investigations were in the fossil floras of the West, in 
connection with the Pacific Railroad report, in 1856; the Macomb exploring 
expedition, 1859; the Ives expedition, in 1861; the Northwest Boundary 
Commission, from 1859 to 1863; and the'Raynolds expedition, from 1859 
to 1860. After this followed numerous investigations in the later extinct 
(Cretaceous and Tertiary) floras of North America, which finally resulted 
in the publication of “Notes on the later extinct floras of North America, 
with descriptions of some new species of fossil plants from the Cretaceous 
and Tertiary strata,” in the Annals of the New York Lyceum of Natural 
History, April, 1868. These descriptions were not accompanied by figures, 
but the plates were subsequently prepared, and were issued in 1878 by the 
United States Geological and Geographical Survey of the Territories 
(Ff. V. Hayden in charge), under the title ‘‘ Illustrations of Cretaceous and 
b] 
Tertiary Plants.” Dr. Newberry’s descriptions were not included, and the 
names to the figures were supplied by Prof. Leo Lesquereux. Dr. New- 
berry would never acknowledge any responsibility for this work. 
In 1873 the volumes of the Ohio Geological Survey were published, 
containmg the results of Dr. Newberry’s previous investigations in the 
fossil flora of the Carboniferous formation in that State, and in 1878 
the rich flora of the New Jersey Cretaceous clays attracted his attention,
