To Martha Chapman Date: DUBLIN, April 5, 1775. MY DEAR SISTER, The apothecary seems to have understood your case; but you have done right in leaving off the taking of medicines. But withal you should use all the exercise you can, particularly in the open air. And use what little strength you have to the glory of Him that gave it. Warn every one and exhort every one, if by any means you may save some. I am, my dear Patty, Yours affectionately.
