1853, and 2: 2,3. 1854. These papers are among the earliest 
contributions to American paleobotany and the specimens de- 
scribed in them are among the earliest described American fossil 
plants. Unfortunately, however, many of these are impossible of 
identification with the descriptions and figures, although for the 
most part they are designated as to name and locality by printed 
labels, evidently text cut from the articles in the Annals of Science. 
nated by the text labels are the exact ones upon which the names 
and descriptions were based, except in the case of those which 
can be identified by means of the figures. 
Other important collections, made by Dr. Newberry person- 
ally, or made by others and reported upon by him, are such as 
were obtained during the prosecution of various government ex- 
plorations, from about 1855-60, viz., the Northwest Boundary 
Commission, the Pacific Railroad and the Macomb, Ives, and 
Raynolds expeditions, in what was at that time generally known 
as “the far West.’’ Just how complete these collections may be 
can probably never be determined, but they contain a large num- 
ber of the type specimens described in certain of the published 
reports of these expeditions and for that reason alone their 
scientific value can hardly be overestimated. 
Subsequently Dr. Newberry was Director of the Ohio Geolog- 
ical Survey and also assisted in the preparation of several paleon- 
tological reports for other geological surveys, and further collec- 
tions of fossil plants were obtained from these sources, the most 
extensive of which is that from the Cretaceous of New Jersey, upon 
which he based his “ Flora of the Amboy Clays,” published in 
1896 as Monographs of the United States Geological Survey, 
Volume XXVI. This latter collection is practically intact and 
includes not only all of the type and figured specimens described 
in the Monograph but also a large number of duplicates which 
serve as valuable material for exchange. 
Among the smaller collections may be specially noted those 
upon which Dr. Newberry based the following contributions :
