Records by a native of Potenza, Italy, are shown in Figs. 7 and 8.
The record of "Mariuccia" begins with some very faint vibrations from the "m." These are followed by stronger ones for the "a".
Fig. 4. Record of "Nutshell." The straight line showing the occlusion for "t" is followed by a rising line showing the rush of air for "sh." This is quite different from the curve for "ch" in Fig. 2.
Fig. 7. Record of "Mariuccia." For "ci" there is no complete occlusion but a steady emission of air ending with an explosion. The curve differs from that of "sh" or "ch."
Fig. 8. Record of "Adagio." The curve for "gi" shows an almost complete closure followed by an explosion; it is a modification of the curve for "ci" in Fig. 7.
The sudden jolts in the line are the record of the two flaps of the tongue for the "r"; the small vibrations indicate that the "r" was sonant throughout (that is, that the larynx was in vibration throughout). Then follow the vibrations for "i" and the more open "u." The sudden
