EDITORIAL REMARK. 
_ WHEN a Controversy turns on the discussion of principles or facts, 
_ promoting the advancement of science—or when an author makes re- 
clamation of discoveries original with himself, and either through igno- 
rance or intention appropriated by another—the pages of the American 
Journal of Science are freely open to a calm and candid exposition 
_ of the case. When however, as in the present instance, science is no 
longer the theme of discussion, and the arguments regard wholly the re- 
spective personal characters of the disputants, and their reputation for ve- 
racity, we feel that we transgress the bounds of editorial propriety by forc- 
ing upon the attention of our readers, matter in no wise interesting beyond 
the limited circle of acquaintances of the several parties, and in excluding 
from our pages papers which are the appropriate contents of a Journal of 
Science. On these grounds we have determined to incur the expense of 
an appendix, not necessarily a part of the Journal, and which subscribers 
can at their option retain or reject when the work is bound. We have 
further, with the knowledge of Mr. Couthouy, submitted a proof of his 
“Review” to his antagonist, that no excuse might exist for another com- 
munication from either, and we take this opportunity publicly to inform 
the parties interested, that this controversy will not again be permitted, 
under the covers of Ne Journal.
