I have just recd. a letter from Mr Johnson, of Octr 29. in which he wishes, if the appointment of Doct. Jones has not been irrevocably made that it may be suspended, til he hears from a friend in New York, whether Mr Renwick, Professor of Nat: Philosophy and highly spoken of at Columbia College, be attainable. This he expects to do in 8 or 10 days, and with some prospect of an affirmative answer to his enquiry. Should you not therefore have notified the appointment of Doct. Jones it seems quite proper to comply with the suggestion of Mr Johnson, who says he will write to me the result of his corrispondence on the subject of Mr Renwick, as soon as he hears from N. York. As the result may reach you before it can go from me, it may be well for you, in that case, and in case Mr. Renwick, be excluded from our option, to write on for Doctr. Jones as suggested in my letter of the 21t. Ult: unless indeed you should think the merit of Mr Walker as described in the inclosed extract,1 entitled to fair consideration. It appears that Jones has just commenced a course of Lectures, and therefore may afford time for it. In conformity to yours and Mr. Cabells sentiments, expressed in his letter from Bremo on the 25th. Ult; I will state to Mr. Long, the solicitude felt to retain his services, and the hope that arrangements may be made with the London University, which will reconcile his engagements here with his object there which it is not wished that he should sacrifice. I will write also to Mr. Gallatin as sujested in the letter of Mr Cabell. With great esteem
