"MY DEAR COLERIDGE,--My mind is disturbed, and my body harassed by many labors; yet I cannot suffer you to depart, without endeavoring to express to you some of the unbroken and higher feelings of my spirit, which have you at once for their cause and object. "Years have passed away since we first met; and your presence, and recollections with regard to you, have afforded me continued sources of enjoyment. Some of the better feelings of my nature have been elevated by your converse, and thoughts which you have nursed have been to me an eternal source of consolation. "In whatever part of the world you are, you will often live with me, not as a fleeting idea, but as a recollection possessed of creative energy,--as an imagination winged with fire, inspiring and rejoicing.... "May blessings attend you, my dear friend! Do not forget me: we live for different ends, and with different habits and pursuits; but our feelings with regard to each other have, I believe, never altered. They must continue; they can have no natural death; and I trust they can never be destroyed by fortune, chance, or accident." Thus his sweet, kindly nature was an inspiration to others. He believed in amiability. He said, later, of temper in the marriage state: "Upon points of affection it is only for the parties themselves to form just opinions of what is really necessary to ensure the felicity of the marriage state. Riches appear to me not at all necessary; but competence, I think, is; and after this more depends upon the _temper_ of the individual than upon personal or even intellectual circumstances. The finest spirits, the most exquisite wines, the nectars and ambrosias of modern tables, will be all spoilt by a few drops of bitter extract; and a bad temper has the same effect in life, which is made up, not of great sacrifices or duties, but of little things, in which smiles and kindness, and small obligations given habitually, are what win and preserve the heart and secure comfort." When Davy was twenty-three, a brilliant opening came to him; came as it did to Cuvier, Newton, and others, through the influence of a friend. Count Rumford had been instrumental in founding the Royal Philosophical Institution for the diffusion of a knowledge of science. Through his works on heat, nitrous oxide, and galvanic electricity, Davy had made the acquaintance of Dr. Hope, the distinguished professor of chemistry in the University of Edinburgh. He recommended Davy to Count Rumford, as fitted for the professorship of chemistry in the Royal Institution, an appointment, Davy wrote to his mother, "as honorable as any scientific appointment in the kingdom, with an income of at least five hundred pounds a year." He had evidently kept the "look towards future greatness" in his heart.
