Letters from Sir Robert Moray to his friend Alexander Bruce, Earl of Kincardine, also known as 'The Kincardine Papers'. Bruce was sick of the ague in Bremen for part of this time, and the letters were written to alleviate the tedium of of Bruce's illness, hence ranging over topics which might not otherwise have been the subjects of correspondence. They include accounts of chemical experiments in his laboratory, his interest in magnetism, medicine in all its aspects, horticulture, fuel, whale fishing, its risks and profits, coal mining, water wheels and tide mills, stone quarrying and the various qualities of different stones, the pumping works needed for undersea coal mines at Bruce's home at Culross in Fifeshire, even to the trees whose wood was best for pipelines, and the diameter of the bore best suited to the purpose. Familiarity is shown with mathematical and surveying instruments, with music, and all sorts of mechanical devices and especially clocks and watches, more particularly the taking out of a patent in respect of a clock for use at sea for finding longitude. Bruce is advised on the choice of books over a wide range of subjects. Moray includes anecdotes to amuse his ailing correspondent; he describes his quiet life and is enthusiastic about many of his chemical experiments. Notable at the end of the letters Moray added what he described as his Masonic signature - a pentagram which also occurs in his crest.

The working drawings of John Smeaton, civil engineer. They illustrate his researches on waterwheels and applied mechanics, and the relative efficiency of overshot as opposed to undershot wheels. With supplementary engravings and manuscript notes.
