I have safely recieved my Polygraph, with which I am now writing, and find it to answer well every where except a small place in the N.W. corner, which is of little consequence. in fact none of them probably can be perfect in every point of the whole field which their dimensions can cover. I now inclose you the 10. D. for the silver pens, & am sorry you did not enable me to judge of the cost of the new machinery & other trouble, which I meant always and wished to pay. if you will do this in your next letter it shall be immediately remitted, together with whatever is due for the profile of my friend mr Wythe. altho’ shewing rather too fleshy a face, yet it is well like him, & far more valuable than the black original. I do not wonder at your not making money by the Polygraphs when you do so much about them for nothing. I expect Capt Lewis here to-day or tomorrow. I presume that after a while he will go on to Philadelphia and carry some of his new acquisitions.   having proposed to Congress the subject of a National university, should they come into it it will be no small part of the gratification I shall recieve from it, that the means will be furnished of making your Museum a national establishment.    Accept my friendly salutations & assurances of great esteem.
