Excerpt from Mathematical Tracts: On the Lunar and Planetary Theories, the Figure of the Earth, Precession and Nutation, the Calculus of Variations, and the Undulatory Theory of Optics; Desiged for the Use of Students in the University In presenting to the University a Fourth Edition of these Tracts, I may perhaps with propriety state the fundamental ideas upon which they were composed. In originally introducing to the notice of the University several subjects which might, in reference to the ordinary pursuits of University students, be considered somewhat abstruse, it was not my intention to offer complete treatises upon any. It appeared to me that the objects of Academical education would be best promoted by giving careful expositions of principles, with rigorous attention to the logic of the reasoning, and with extent of application sufficient to lead to results of interesting character; but not by pursuing each subject to its remote details. I therefore adopted the following rules: - 1. To carry each subject carefully and accurately to a certain point, at which all the characteristic difficulties should have been met and overcome. 2. To indicate briefly the nature of the process to be pursued in going further, but not to go into details. 3. In the selection of methods, to adopt in preference those which carry with them the best geometrical evidence, as distinguished from symbolical operation, which the nature of the investigation may permit.
