which are lost or missing. In a number of instances manuscript descrip- 
tions were found for which there were no corresponding figures on the 
plates. Wherever such figures could be supplied from the named material 
in the collection this was done, but in case of the slightest doubt as to the 
identity the description was omitted entirely. Again, it was found that 
many of the figures were named but not deseribed, and others were not 
even named. In the first instance descriptions were supplied, and in the 
second, wherever such a figure could be identified with its type specimen 
in the collection, the name attached to the specimen was adopted and a 
description added. In case no name or type specimen could be found for 
a figure an effort was made to identify it with some previously described 
species, and, failing in that, a description was written and an entirely new 
name adopted. The responsibility of the editor in all such cases is indi- 
cated by his initials; but in order to avoid any possible confusion in the 
future the authority for the new name is given in each instance after 
the name. 
In conclusion, | wish to acknowledge my indebtedness to Prof. Lester 
F. Ward for assistance in verifying references, for corrections in terminology 
and nomenclature, and for bibliographic research, without which the com- 
pletion of the work in its present shape would have been impossible. 
After the foregoing was written Dr. Newberry died, and the present 
seems to be a proper time in which to give a brief review of his contri- 
butions to fossil botany. Accounts of his general scientific labors have 
been so faithfully given elsewhere by many friends and former associates, 
in various publications and in the records of scientific societies, that a 
repetition of them here would be superfluous. The editor will therefore 
confine himself solely to an account of Dr. Newberry’s activity in the line 
of paleobotany.
