Robert Morris writes to Benjamin Franklin and includes an extract from a letter written by Thomas Jefferson in which he expresses a desire for a copying machine (presumably a letter copying press) that Franklin was using. Jefferson requests that Morris attempt to obtain one for him as well as a dozen reams of paper which he will pick up in Philadelphia in November. Morris sends the request to Franklin as he believes that Jefferson is wrong to think that England, over France, is the place to obtain one.; American Philosophical Society
