A second knife-edge, i), which can be raised orlowered, is attached to the bar. The brass frame is swung free bymeans of two transverse steel rods, E, attached by joints, F, allow-ing of vertical and horizontal adjustment, to four vertical steelrods, Gy each pair being inserted into a bar of wood covered withleather, by which the instrument rests on the ciiest. The button ispressed on the site of the impulse by a spring, the force being ad-;iustable with a screw, iT, which perforates the short arm of thespring-lever, B. There are also two small springs, i of differentstrength, to depress the long lever and prevent its being jerkedaway from its knife-edge by a sudden movement.

The bagscommunicate with a registering apparatus by separate compart-ments of the tube, ending in separate tubes, TO and TV, There isalso a third tube, TO, having a similar bag, C, at its free end, whichis secured in an incision over the situation, of the apex-beat; this,too, communicates with the registering apparatus.
