“The chief object of the present work is, as its title indicates, to furnish to the student examples by which to illustrate the processes of the Differential and Integral Calculus. In this respect it will be seen to agree with Professor Peacock's Collection of Examples; and indeed if a second edition of that excellent work had been published I should not have undertaken the task of making this compilation. But as Professor Peacock informed me that he had not leisure to superintend the publication of a second edition of his "Examples" which had been long out of print, I thought that I should do a service to students by preparing a work on a similar plan, but with such modifications as seemed called for by the increased cultivation of Analysis in this University.”

“In education … whenever a proposal is made that looks toward increased intellectual effort on the part of students, professors will always say that the students cannot so the work. My observation leads me to think that what this usually means is that the professors cannot or will not do the work … When, in spite of the opposition of the professors, the change is introduced, the students, in my experience, have always responded nobly.”

“We’d have a motherfucking shitload of dogs! Horses. Peacocks. Oh to live among peacocks. I’d seen them once in person and they defied so many laws of color and gravity that they had to be made geniuses waiting to take over everything.”

“In this chapter I shall collect those Theorems in the Differential Calculus which, depending only on the laws of combination of the symbols of differentiation, and not on the functions which are operated on by these symbols, may be proved by the method of the separation of the symbols : but as the principles of this method have not as yet found a place in the elementary works on the Calculus, I shall first state? briefly the theory on which it is founded.”
