they are entirely supported by the benevolence of thepublic. I trust, ere long, their permanence will besecured by a national institution, embracing the wholepopulation. I feel much gratified by the opportunity you afford-ed me, of making the acquaintance of Dr. Francis.A mind more ardent in the pursuit of useful knowledge, perhaps, never existed; and, I have no doubthe will, in a few years, stand at the head of his pro-fession. I introduced him to my son-in-law, Dr. Yeats,who is an able and learned physician,; he entertainsa high opinion of your friend's talents, and, I amsure, will, at all times, be happy in the opportunity ofbeing useful to him. My health declines, as may naturally be expected,as old age approaches; but, upon the whole, I haveno reason to complain. Regularity and temperanceare my chief and best medicine for all complaints. I shall always be happy to hear from you, and tomake such communications as I conceive may beuseful to mankind in general; but let me entreat ofyou, my good friend, not to make my letters public.Engaged, as I constantly am, in a great variety of pursuits, I can only snatch a moment occasionally forprivate correspondence, which can never be sufficientlycorrect for the public eye. I send by Dr. Francis, a parcel, containing suchpublications as are likely to prove interesting to you.A list of them you will find hereunto annexed. With every sentiment of esteem and respect,I remain always, dear Sir,Yours, truly and affectionately, P. COLQUHOUN.To Mr. THOMAS EDDY, New York.
