In a recent volume of memoirs by Mrs. Schimmel Pennick, we find the following graphic sketch of this extraordinary man:--"He was one of the most complete specimens of the melancholic temperament. His head was generally bent forward or leaning on his hand in meditation, his shoulders stooping, and his chest falling in, his limbs lank and unmuscular, and his complexion sallow. His utterance was slow and impassioned, deep and low in tone, with a broad Scotch accent; his manners gentle, modest, and unassuming. In a company where he was not known, unless spoken to, he might have tranquilly passed the whole time in pursuing his own meditations. When he entered the room, men of letters, men of science, many military men, artists, ladies, and even little children, thronged around him. I remember a celebrated Swedish artist being instructed by him that rat's whiskers made the most pliant painting-brushes; ladies would appeal to him on the best modes of devising grates, curing smoking chimneys, warming their houses, and obtaining fast colours." His reading was singularly extensive and diversified. He perused almost every work that came in his way, and used to say that he never opened a book, no matter what its subject or worth, without learning something from it. He had a vivid imagination, was passionately fond of fiction, and was a very gifted story-teller himself. When a boy, staying with his aunt in Glasgow, he used every night to enthral the attention of the little circle with some exciting narrative, which they would not go to bed till they had heard the end of; and kept them in such a state of tremor and excitement, that his aunt used to threaten to send him away. Since Watt's time, innumerable patents have been taken out for improvements in the steam engine; but his great invention forms the basis of nearly all of them, and the alterations refer rather to details than principles of action. The application of steam to locomotive purposes, however, led to the construction of the high pressure engine, in which the cumbrous condensing apparatus is dispensed with, and motion imparted to the piston by the elastic power of the steam being greater than that of the atmosphere.
