Arithmetical

I do come home at Christmas. We all do, or we all should. We all come home, or ought to come home, for a short holiday — the longer, the better — from the great boarding-school, where we are forever working at our arithmetical slates, to take, and give a rest.

Again, having divided the calculus into algebraic and arithmetical, M. Comte admits, as perforce he must, that the algebraic is more general than the arithmetical; yet he will not say that algebra preceded arithmetic in point of time.
