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 this Journal.

 Joseph P. Couthouy. 



At the time when I submitted to the public through the medium of 

 the American Journal, my reply to the charge of plagiarism preferred 

 against me by Mr. Dana in the number for July, 1843, I presumed that 

 the subject would be permitted to rest until the approaching meeting of 

 the Association of American Geologists and Naturalists, at which I had 

 solemnly pledged myself to substantiate by indisputable testimony the 

 statement contained in that reply. 



As Mr. Dana, however, has deemed it advisable to follow up the ques- 

 tion during the interval by the publication in the last number, of several 

 pages of comments upon my vindication, and has in these comments not
