On the two Editions of Emory’s Report, 1848, 
For some time past I have been aware of the fact that there 
were two editions of Lieut. W. H. Emory’s “ Notes of a Military 
Reconnoissance,” both bearing the same date (1848); but I sup- 
posed they were identical, except that one had appended to it the 
reports of Abert and Cooke and the journal of Johnston. But I 
now possess copies of both of these books, and find that they dif- 
fer in various details, which are of importance on account of Prof. 
Torrey’s reports on the botany of the expedition. 
Both editions are Executive Documents of the 30th Congress, 
Ist session, and they are numbered 7 and 41, respectively. No. 7 
was issued for the Senate. It contains nothing but Emory’s re- 
port, with its seven appendices, and consists of 416 pages. Each 
age has[* ]in the upper external corner. No. 41 was issued 
for the House. It contains the reports of Emory, Abert and 
Cooke, and Johnston’s journal, and consists of 614 pages. “ Ex. 
Joc, No. 41," appears in the middle of the top of each page, with 
the exception of pp. 145-158, in the botanical portion, which have 
[7] in the upper external corner. This is evidently a tyP? 
graphical error, and not a mistake in binding, for the pages af 
not the same as pp. 145-158 in No. 7. 
In both of these volumes Professor Torrey’s report on Emory’s 
plants occupies pp. 135-159, constituting Appendix No. 2. My 
copy of No. 41 bears the following manuscript note at the top of 
page 135. “ This appendix is full of gross typographical errors— 
the printer having refused to send me proof sheets according to 
agreement. J. Torrey.” The same remark would apply with 
equal force to No. 7. Both books show evidence that they were 
published either carelessly or in very great haste. The principal 
differences between the two documents in the botanical portions 
are as follows:
