| Description | Docketed "About experiment on the quantity of ? in water and tube condensers."
Summarised "Boulton’s trials and remarks about the tubular condenser, and concerning Watt’s first model of one. Thinks Hornblowers make this their point since Henderson divulged. Do not care for plates in preference to tubes. Will watch Onions if he bores any cylinders with his new mill. Re. Arkwright’s invention. Re. red hot steam etc." |
