Not illustrated. 1895 Excerpt: ...Record of Movement.--Movements, such as we shall have to deal with, are generally too extensive to be directly recorded by means of a tracing needle. In jumping, for instance, the head may be elevated any distance between 30 and 50 centimetres in a vertical direction. This movement must be reduced to such proportions as can be registered on the surface of a revolving cylinder. This reduction can be effected by means of the elasticthread method previously described (Fig. 29). If a man stands on the platform of a dynamograph, and wears a very tight-fitting cap, the elastic thread may be fastened at one end to the cap, and at the other to a solid support by means of a clip (Fig. 101). This thread may be fixed near its upper end to the lever All effects which are produced during the performance of a movement are followed, when the movement is concluded, by counter effects in the opposite direction.

Two recording tambours register two curves on a revolving cylinder, one the curve of footpressure, and the other that of the vertical discursions of the head. Examination of these curves, enlarged, if necessary, shows that in all respects the laws of animal movements conform to general laws--in this case to the laws of ballistics. The areas of the curves which are described by the P' $ Fig. 102.--Superior curves; changes of height in the head during the jump. The frtyr' ordinates DC and DC are proportional to the height of the j ump. fW Inferior curves; pressure exercised by the feet on the ground. The shaded areas Ay show the quantity of movement communicated to the body in the two jumps. dynamographic needle express the...
