Excerpt from Scientific Papers, Vol. 2
This volume contains, in addition to a farther selection from scientific papers, a few articles reprinted from the last edition of the Encyclopaedia Britannica; and an Introductory Lecture to my Ordinary Class, devoted mainly to the question of how Natural Philosophy ought, as well as how it ought not, to be taught. For permission to reprint these I am indebted to the courtesy of Messrs A. & C. Black, and of Messrs Isbister, respectively.
I have been assured by competent judges that my remarks on Science Teaching, as it is too commonly conducted, are not only in no sense exaggerated, but are even now as appropriate and as much needed as they seemed to me twenty years ago.
To the short article on Quaternions I was inclined to attach special importance, of course solely from the historical point of view; for (in consequence of my profound admiration for Hamilton's genius) I had spared neither time nor trouble in the attempt to make it at once accurate and as complete as the very limited space at my disposal allowed. Yet, us
will be seen from the short note now appended to the article, the claims of Hamilton to entire originality in the matter have once more been challenged: - on (his occasion in behalf of Gauss. [It is noteworthy that Hamilton himself seems to have had at one time a notion that, if he had boon anticipated, it could have been only by that very remarkable man. But he expresses himself as having been completely reassured on the subject, by a pupil of Gauss who was acquainted with the drift of his teacher's unpublished researches. See Hamilton's Life, Vol III. pp. 311-12, 326.]
