From William Canton6
AL: Historical Society of Pennsylvania
<Wednesday evening, March 18, , a note in the third person. His father, who is considerably worse than the previous Saturday, but because of laudanum in not quite so much pain, thanks Franklin for his kind inquiry.>
6. The son and subsequently the biographer of BF’s old friend; see the DNB under John Canton.
7. Four days before John Canton’s death. BF’s cash book (1772, 1778–80; APS) shows that he had visited Canton, presumably for the last time, on March 5.
