Washington 25 April 1824
My dear Sir
I take great pleasure in presenting to you the bearer of this letter, Mr Julis de Wallenstein, a Secretary of the legation of his Majesty the Emperor of Russia—He visits Boston & other parts of our Country for the improvement of his health, & with purposes of enlightened curiosity. Upon the most transient conversation with him, no testimonial will be needed to mark him in your estimation as a person of extensive Literature, profound science, & elegant taste. A longer acquaintance with him enables me to appreciate the urbanity of his deportment & the delicacy of his sentiments. He will be esteemed in proportion as he is known.
I am Dear Sir, in dutiful affection, Your Son—
