Another and unsigned letter from Philadelphia provoked equal thought, especially for the following passage:
"I will observe what you say respecting the sending of Accounts only by yr Vessels, but can not always be certain when to expect them. In the Matter spoke of, I require only one more thing; but wish to be sure I apprehend you exactly.
