To Alexander Knox Date: LONDON, February 26, 1778. DEAR ALLECK, - In the latter end of March I hope to be in Dublin, and about the 28th of May in Londonderry. preached on May 28 in Londonderry, and stayed till June 4. It is a place I always loved; but I shall love it more than ever if I have the pleasure of lodging with you. With regard to your health, both of body and mind, if you could take one advice it would have a surprising effect. It is this: 'Take no thought for the morrow.' You know not how much even your body suffers by this. To-day only is yours. Look up, and He will bless you all to-day. - I am, my dear Alleck, Very affectionately yours.
