[ [72] The club he frequented was called the Anderston Club, of which Mr. (afterwards Professor) Millar, Dr. Robert Simson, the mathematician, Dr. Adam Smith, Dr. Black, and Dr. Cullen, were members. The standing dish of the club was hen-broth, consisting of a decoction of “how-towdies” (fowls), thickened with black beans, and seasoned with pepper. Dr. Strang says Professor Simson was in the habit of counting the steps from his house to the club, so that he could tell the distance to the fraction of an inch. But it is not stated whether he counted the steps on his return, and found the number of steps the same.
[ [73] John Anderson was a native of Greenock, and an intimate friend of James Watt. He was appointed professor of Hebrew in his twenty-seventh year, and succeeded Dr. Dick as professor of Natural Philosophy in 1757. Watt spent many of his evenings at his residence within the College, and had the free use of his excellent private library. Professor Anderson is entitled to the honour of being the first to open classes for the instruction of working men—“anti-toga classes,” as he called them—in the principles of Natural Philosophy; and at his death he bequeathed his property for the purpose of founding an institution with the same object. The Andersonian University was opened in 1796, long before the age of Mechanics’ Institutes.
[ [74] At a meeting held in Glasgow in 1839 to erect a monument to Watt, Dr. Ure observed:—“As to the latent heat of steam,” said Mr. Watt to me, “it was a piece of knowledge essential to my inquiries, and I worked it out myself in the best way that I could. I used apothecaries’ phials for my apparatus, and by means of them I got approximations sufficient for my purpose at the time.” The passage affords a striking illustration of the large results that may be arrived at by means of the humblest instruments. In like manner Cavendish, when asked by a foreigner to be shown over his laboratories, pointed to an old tea-tray on the table, containing a few watch-glasses, test papers, a balance, and a blowpipe, and observed, “There is all the laboratory I possess.”

[ [76] The following advertisement in the ‘Glasgow Journal’ of the 1st Dec., 1763, fixes the date of this last removal:—
“James Watt has removed his shop from the Saltmercat to Mr. Buchanan’s land in the Trongate, where he sells all sorts of Mathematical and Musical Instruments, with variety of toys, and other goods.”

[ [79] “The last step of all,” says Professor Jardine, “was more difficult—the forming of the separate condensing vessel. The great knowledge he had acquired of the mechanical powers enabled him to construct it, but I have often heard him say this was a work of great difficulty, and that he met with many disappointments before he succeeded. I have often made use of this beautiful analysis received from Mr. Watt, in another department in which I have been long engaged, to illustrate and encourage the progress of genius in youth, to show, that once in possession of a habit of attention, under proper direction, it may be carried from one easy step to another, till the mind becomes qualified and invigorated for uniting and concentrating effort—the highest exertion of genius.”
[ [80] “I have now (April, 1765) almost a certainty of the facturum of the fire-engine, having determined the following particulars: The quantity of steam produced; the ultimatum of the lever engine; the quantity of steam destroyed by the cold of its cylinder; the quantity destroyed in mine; and if there be not some devil in the hedge, mine ought to raise water to 44 feet with the same quantity of steam that theirs does to 32 (supposing my cylinder as thick as theirs), which I think I can demonstrate. I can now make a cylinder 2 feet diameter and 3 feet high, only a 40th of an inch thick, and strong enough to resist the atmosphere; sed tace. In short, I can think of nothing else but this machine.”—Watt to Dr. Lind, quoted in Muirhead’s ‘Life of Watt,’ 94–5.
