To endeavour oneself

P. C. S. S. begs leave to observe, in answer to the question of G. P. in the eighth number, that the use of the verb "endeavour" which G. P. cites, is also to be found in Shakspeare's *Twelfth Night*, Act IV. Sc. 2.:— Malvolio, Malvolio, thy wits the Heavens restore! *endeavour* thyself to sleep, and leave thy vain bibble-babble."
