Jan Ingenhousz to Benjamin Franklin, June 23, 1783

Vienna juin 23 1783.

Dear Friend

This is only to accompany the adjoin’d lettre of mr. Weinbrenner, who, as you see, does
not loose time to make use of your kind proposition of giving some introductory letters
to his agent, who is mr. Donath . This gentleman will set
out in a few weeks for Philadelphia New york & Boston, where he will spend two
years. He will carry with him various productions of this Country. I hope you will as
soon, as Convenient for you, grant the request of Mr. Weinbrenner. 1

Your original lettre with the medal inclosed is not yet come to hand, 2 neither the Philadelphia
Almanach, you was so good as to send me a year ago. 3

The Cast of my profil, I send you, is made in the usual manner of gypse or plaster of
Paris; which being dryed is smeared over with parchment glue or glue of ising glas
warmed. When this kind of varnish is thereabout dry, the whol is covered, by means of a
very fine brush or pencil, which silver dust, called silver
bronze , to be got every where in Colour Shops. The parts of the cast thus
finish’d, which aught to be polishd, are rubbed with a polish’d piece of steel.

Your advise about the statuary was thankfully recieved and much approved of. I recieved
at last from mr. le Begue the first 5 sheats of my book under the press at Paris. I did
not find one Single typographical error in them.

I hope still to see you here with your grandson before you set out for your beloved
America.

I am with the greatest estime Your most obedient Serv and affectionate friend

J. Ingen Housz
