 Dear Sir,


         Your favor of the 30th April, accompanying
 the conversations on Botany & three Nos of the Annals of the
 Lyceum, containing the Prunus americana, [came?] to hand on the
 19th of May - two or three days after the time proposed for your
 excursion to Quaker Ridge; otherwise I should have made
 an effort to have gone with you.  I am much obliged by
 the contents of your package.  The Conversations I had not
 previously met with.  They furnish the best introduction to the
 study of the Natural Method, that I have seen.


     I have prevailed on the youn lady who made the
 drawing of our Prunus, to execute one of our Euphorbia,
 agreeably to your wish; and now forward it herewith.
 The plant grows so large, that I was compelled to
 select an inferior specimen in order to have it within
 bounds.  Even this will be too large for the Annals, un-
 less the engraver confines himself to just as much of
 the top of the plant as will go in a page, - or else
 the sheet will have to be doubled in the book.  You can
 deteermine which mode will be most eligible.  Some
 of the first specimens, where I collected the original of
 this drawing, were full five feet high, with long slender
 peduncles from the axils of all the leaves near the top
 of the plant - giving it the appearance of a great [Parricle/Pannicle?]
 I am apprehensive the roots  I sent to Mr. Prince, will
 not have flowered this season, so as to give you a good
 opportunity to study it in the growing state; but I hope
 they may next year.  I am very desirous you should see
 the plant to the best advantage, before pronouncing
 finally on its character as a non-descript.  I have not
 the slightest doubt of its being indigineous with us:
 but, if there is an reliance to be placed on [Pursh's?] "v.v.",
 I am inclined to suspect it must be the species he in-
 tends by the name E. pilosa, which Willd.locates in Siberia.
