look true. Persons who are narrating facts, are seldom so particular as Mr. Kissam seems to be, about day and date and precise location. Besides, if Mr. Kissam actually did come upon the discovery he says he did, at the period designated—nearly eight years ago—how happens it that he took no steps, on the instant, to reap the immense benefits which the merest bumpkin must have known would have resulted to him individually, if not to the world at large, from the discovery? It seems to me quite incredible that any man of common understanding could have discovered what Mr. Kissam says he did, and yet have subsequently acted so like a baby—so like an owl—as Mr. Kissam admits that he did. By-the-way, who is Mr. Kissam? and is not the whole paragraph in the ‘Courier and Enquirer’ a fabrication got up to ‘make a talk’? It must be confessed that it has an amazingly moon-hoaxy-air. Very little dependence is to be placed upon it, in my humble opinion; and if I were not well aware, from experience, how very easily men of science are mystified, on points out of their usual range of inquiry, I should be profoundly astonished at finding so eminent a chemist as Professor Draper, discussing Mr. Kissam’s (or is it Mr. Quizzem’s?) pretensions to the discovery, in so serious a tone.     

       But to return to the ‘Diary’ of Sir Humphrey Davy. This pamphlet was not designed for the public eye, even upon the decease of the writer, as any person at all conversant with authorship may satisfy himself at once by the slightest inspection of the style. At page 13, for example, near the middle, we read, in reference to his researches about the protoxide of azote: ‘In less than half a minute the respiration being continued, diminished gradually and were succeeded by analogous to gentle pressure on all the muscles.’ That the respiration was not ‘diminished,’ is not only clear by the subsequent context, but by the use of the plural, ‘were.’ The sentence, no doubt, was thus intended: ‘In less than half a minute, the respiration [being continued, these feelings] diminished gradually, and were succeeded by [a sensation] analogous to gentle pressure on all the muscles.’ A hundred similar instances go to show that the MS. so inconsiderately published, was merely a rough note-book, meant only for the writer’s own eye, but an inspection of the pamphlet will convince almost any thinking person of the truth of my suggestion. The fact is, Sir Humphrey Davy was about the last man in the world to commit himself on scientific topics. Not only had he a more than ordinary dislike to
