Instead of muscular or other movements being communi-cated directly to levers, the contact may be through columnsof air, which, it will be apparent, must be capable of communi-cating very slight changes if the apparatus responds readily tothe alterations in volume of the inclosed air.

Fig. 171.—Tambour of Marey (after McKendrick). a, metallic case; b, thin India-rub-ber membrane; c, thin disk of aluminium supporting lever d, a small portion ofwhich only is represented; e, screw for placing support of lever vertically overc;/j metallic tube communicating with cavity of tambour for attachment to an In-dia-rubber tube. tially of a rigid metallic case provided with an elastic top, towhich a lever is attached, the whole being brought into com-munication with a column of air in an elastic tube. The work-ing of such a mechanism will be evident from Figs 170 and 172. 1
