It being always somewhat uncertain whether Genl. Cocke will be found at Bremo, or at Charllle; whither he is so often called I trouble you agn. with a letter for him to be properly disposed of as the case may be. The letter being left open for your perusal, you will see that Mr. Key has decided on a return to Engd. & that we have to encounter the difficulty of providing a Successor. His letter shews that his purpose of resigning had never been relaxed. It is not impossible that his thoughts & hopes may be turned to the London University about to be established. You will observe also what is said to Genl. Cocke & to be sd. to the other Visitors on the subject of gathering the information necessary to the choice of a Successor to Mr. Key & including such as may be drawn from the other Engsh. professors. This last source you may yourself have good opportunities of sounding & I hope you will avail your self of them, and in general co-operate with us in gaining the information we need. Have you learnt any thing further of Mr Nuttal? Mr. Key has expressed a very favorable opinion of Hassler’s Trigony. but thinks it less fitted in some respects to be a text Book than that of La Croix translated by Farrar.1 Hassler’s is how ever much commended in the Amn. Review under the Auspices of Mr. Walsh; and is I understand adopted as a Text Book in the College at Washington, and in another in New York. Be so good as to forward the enclosed to Genl Breckenridge.
