These were made by Charles Chevalier who made the large vacuum pump (Figure 80). They are designed to accomplish three types of action -- suction, elevation, and forcing. We would speak of them as lift and force pumps. The larger pump (Figure 59) has glass receptacles and other parts which are interchangeable. The catalogue of Chevalier calls them "très beau modelé" and lists them at 345 francs. A very good account of pumps, etc., with many experiments fully described, is given by N.B. and D. Chamberlin, (A Catalogue of Pneumatic Instruments, Etc., Boston, 1844). This catalogue also gives good explanations of the use of attachments for vacuum pumps. N.B. Chamberlin (Descriptive Catalogue, Boston, 1855) mentions, as does almost every nineteenth century catalogue, the hydrostatic paradox (Figure 40).Collection
