Mr Kalm being now on his return home, I cannot suffer him to go, without acknowledging the favours which I have received from you, a person so highly esteemed & distinguished in the republic of letters, & to whom the world owes so much, by the vast acquisition in knowledge which it has gain’d, in Botany & all parts of natural history, by your wonderful Skill and indefatigable labours. My last to you was entrusted to Mr Kalm’s care. In it I gave you several corrections of the Botanical observations which Gronovius sent to you from me, & which Mr Kalm told me are published in the Acta of your Academy. I hope you received them before those observations were published, & that the proper corrections were made before the publication. I am very desirous to see them as they are printed, & I must beg the favour of you to send them to Mr Collinson in London for me, if you have no opportunity of sending them to Philadelphia, if you have then please to direct them to the care of Mr Benjamin Franklin Post Master in Philadelphia, because I know not otherwise how to obtain them.
Mr Kalm has so much more knowledge in Botany & in Natural History than any in this Country can pretend to, & he has been so industrious, & has undergon such great difficulties in travelling through a great part of this vast Forest, & risked such dangers in his person from its Savage inhabitants, that as on the one hand, his zeal in the pursuit of knowledge cannot be sufficiently applauded, so on the other hand, I have no hopes left me, that I can be of farther use to you. However, Sr if there remain any thing in which you think I can give you information, you will give me the greatest pleasure in receiving your commands. And though it be too probable, that you may have no such inducement to write to me, yet I hope you will so far favour a person who has the greatest esteem for your merit, as to let me some- times know that you live & continue an ornament of your Country, by giving some account of the fruits that you daily produce
