Three Editions of Emory’s Report, 1848, 
A note “On the two editions of Emory’s report, 1848" 
has recently been published by Mr. John H. Barnhart,* de- 
scribing the principal differences in the botanical appendices of 
Major W. H. Emory’s « Notes of a military reconnoissance, from 
Fort Leavenworth, in Missouri, to San Diego, in California, in- 
cluding part of the Arkansas, Del Norte and Gila rivers.” These 
differences are that in Document 41, printed for the Senate, the 
“explanation of plates” is omitted, as well as the matter on 
Zinnia grandifiora, Convolculus nuttallii, and Altenanthera lanugt- 
nosa, the last two being new names; that the plates in No. 41 
were lithographed by C. B. Graham, Washington ; those in No. 7 
_ by E. Weber & Co., Baltimore, the name on plate vi. in the former 
_ being Baileya multiflora, in the latter Baileya multiradiata ; and 
*Bull. Torr, Club. 22: 394-5. 1895.
