Thursday Feb 24th 1876

  1. The Capsule arranged as in Fig 2 (page 27) was tried this morning. An intermittent current from one of the Transmitters was passed through the helix (H) by means of the wires W, w'. The little cylinder C' vibrated against the end of the large cylinder C reproducing the note due to the Transmitting Instrument. The reflection of the flame was watched in a mirror backwards and forwards as in Fig I. Mirror Axes
    m'm' being the initial position q the mirror it was swung so as to assume successively the positions mm; m2m2; m,m; m'm'; mm; m2m2 +c.
    The imaginary axis a was vertical. No trace of vibration was perceptible in the reflected flame.

  2. The capsule was disconnected from the helix H (Fig 2. p.27) and held in front of the spring armature S (Fig 2 p.31) of one of the new Receivers. When the intermittent current was passed through w m w' the spring, S, vibrated and immediately the flame reflection was resolved into waves of light of the form and appearance of those shown in (a )(Fig 2) upon pressing S against the end of the pipe, p, the flame waves presented the appearance shown in b
