Mr. A. Lee presents his respectful Compliments to Doctor Franklin, and begs the favor of him to revise and certify the enclosed state of facts while they are fresh in his memory, in order to prevent disputes about matters of fact, which Mr. Lee feels to be as unbecoming as it is painful. Mr. Lee wishes to add to the observations on the ingenious theory Dr. Franklin was so good as to explain yesterday that the roots of trees and plants which are deprivd of light are found of all Colours.
