I. In No. 7 Prof. Torrey’s general report occupies pp. 13-5 
155; page 156 contains an “ Explanation of the Plates; and on 
PP. 157-159 is a letter from Dr. Geo. Engelmann describing (from 
drawings only) the Cactaceae of the Expedition, in fine print. In 
No. 41 Prof. Torrey’s general report occupies pp. 135-155 (but 
the matter on the various pages is differently distributed); Dr. 
Engelmann’s letter extends from page 155 to page 159; and chere 
#s no “« Explanation of the Plates.” 
2. In No. 41 three species are entirely omitted which are 
given in No. 7, viz.: (a) Zinnia grandiflora Nutt., (6) Convolvulus 
Nuttallii,and (c) Alternanthera? (Endotheca)lanuginosa. Of these (a) 
and (c) are described, and (4) and (c) are published as new names. 
A person having reference to these in “ Emory’s Mil. Rec.” and 
looking them up in No. 41, would be puzzled at their absence, 
and conclude that the references were incorrect. 
3. The fourteen plates in No. 7 were lithographed by E. Weber 
& Co., Baltimore. Those in No. 4! are similar, but were litho- 
8taphed by C. B. Graham, Washington. The latter are somewhat 
better (or less bad), from an artistic standpoint, but there seem to 
be no differences of importance—save that in No. 41 plate VI. is 
labeled Baileya multiflora instead of B. multiradiata. 
4. In both documents Appendix No, 6, occupying pp. 386-— 
414, consists of Lieut. Abert’s “ report of such objects of natural 
history as came under my observation while I was attached to the 
topographical party * * * during the journey from Fort Leaven- 
Worth to Bent’s Fort. The plants which were collected were sub- 
mitted to the inspection of Dr. Torrey, to whom I am indebted 
for their names.” Prof. Torrey’s list, to be found on pp. 406-414, 
differs somewhat in the two books, but this is of little importance, 
for it is a mere catalogue of names, without descriptions. 
I hope that this note, published in the BULLETIN, may help to 
Prevent trouble and confusion in the future.
