From William Heberden5
AL: William Pepper, Philadelphia (1956)
[Before September 29, 1766]6
Dr. Heberden sends his compliments to Dr. Franklin and desires the favor of his company at dinner on monday next (Sept. 29th.) at half an hour past three.
5. On Dr. Heberden, distinguished physician, for whose pamphlet on smallpox inoculation BF had written the preface, see above, VIII, 281.
6. Since the invitation was for “monday next (Sept. 29th.),” it must have been written during the previous week. September 29 fell on a Monday during BF’s English years only in 1760 and 1766, and BF was on a journey to Coventry, Worcester, and Birmingham from about September 17 to November 1 in 1760 (above, IX, xxvi, 231 n), hence this invitation is assigned to 1766.
