1. The receipt is in a clerk’s hand, with an emendation “long” by Capt. James Shirley, who signed it; the rest is in Collinson’s.
2. Not identified; possibly reports of BF’s additional experiments.

In response to Dalibard’s account of the Marly experiment, addressed to the French Academy of Sciences, May 13, 1752, which the author sent him, BF sent copies of reports of his additional experiments, and reports of still others later on. See Dalibard’s translation of Exper. and Obser. (2d edit., Paris, 1756), 1, 23–4.
4. In Phil. Trans., XLVII (1751–52), published in 1753, there was one article by Collinson and several in the form of letters to him.
5. John Bartram’s son William (1739–1823), a student in the Academy of Philadelphia, was already a promising artist, whose “pretty performances” in drawing plants and flowers Collinson encouraged by rewards and orders.
