16 fine folding engraved plates (a little waterstained in lower corners). xii, 98 pp. Large 4to, cont. calf (some rubbing & a bit of worming), spine gilt. Bayreuth: Heirs of J.A. Lübeck, 1800. First edition and quite rare. Baader (1763-1835), a prominent mining expert and Chief of the Bavarian Mining Council, resided in England and Scotland from 1786 to 1794, where he studied the most recent technological developments, both in mining and metallurgy. While in Edinburgh, he designed a new blasting machine for iron mines which had considerable success and became known as the Baadersches Geblaese. His greatest contribution to science was, however, his devotion, through propaganda and the power of his position, to the building of railways in Bavaria. The present work is the sequel to Baader's famous Vollständige Theorie der Saug- und Hebepumpen (1797), in which Baader described his theory of suction and design of water lifting pumps. These two books attracted the attention of the Elector Max IV Joseph of Bavaria, who commissioned Baader in 1802 to design and build several new pumping stations to irrigate the gardens of Nymphenburg Palace and supply its fountains. These pumping stations are the oldest still-operational water pumps in Europe and are considered milestones of engineering. Napoleon was so impressed by these pumps that he called Baader to Paris in 1805 to help with the technical improvement of the machine of Marly and improve the water supply of Versailles. However, Baader's proposals were not realized. This work was written while Baader was director of mining and machinery in Bavaria. It is concerned with various kinds of pumps used in mines, to flood brine pools, and to transport brine solutions. The finely engraved plates depict various parts of the pumps, mostly in cross-section views. A little spotted and some dustiness but a very good copy. ❧ A.D.B., I, pp. 725-26. Poggendorff, I, 80-81.
