Sydney Smith to Miss Lucie Austin, July 22, 1835:

Lucy, Lucy, my dear child, don’t tear your frock: tearing frocks is not of itself a proof of genius; but write as your mother writes, act as your mother acts; be frank, loyal, affectionate, simple, honest; and then integrity or laceration of frock is of little import.

And Lucy, dear child, mind your arithmetic. You know, in the first sum of yours I ever saw, there was a mistake. You had carried two (as a cab is licensed to do), and you ought, dear Lucy, to have carried but one. Is this a trifle? What would life be without arithmetic, but a scene of horrors?

You are going to Boulogne, the city of debts, peopled by men who never understood arithmetic; by the time you return, I shall probably have received my first paralytic stroke, and shall have lost all recollection of you; therefore I now give you my parting advice. Don’t marry anybody who has not a tolerable understanding and a thousand a year; and God bless you, dear child.

Sydney Smith
