If you are feeling up to a minor adventure, and if it would in no way interfere with whatever it is you are supposed to be doing for Princess Caroline, I should be indebted if you were to (1) learn from Mr. Orney when those ships are expected to sail for St. Petersburg, and (2) before they do so, freight them, as much as you can, with goods that might be of use, or at least of interest, to aspiring Russian Natural Philosophers, viz. thermometers, scales, lenses, toad’s-eyes, unicorn’s-gallbladders, Philosopher’s Stone, and the like; and (3) for God’s sake give the Tsar something to show for our work of the last fifteen years. If you can arrange for your note-cards to be shipped over from Boston in time, that is ideal. Short of that, any tangible evidence that you have been doing something at the Massachusetts Bay Institute of Technologickal Arts, may help to keep your humble and obedient servant from being broken on a wheel before the Russian Academy of Sciences, as an example to Scientists who draw stipends without yielding Science.
