The vibrator was tuned by comparison with a Konig fork to 192 vibrations per second, in order that a resonator responding to that note might be used in listening at F. The object of this was to get rid of the overtones which helped to mask the minima. The platinum point which dips into the mercury was attached to a slender brass spring, tuned to the same pitch as the vibrator in order to secure greater amplitude. The spring was about 35 mm. Long, and its amplitude at the free end was as great a...s 3 mm. , about 10 times that of the end of the vibrator bar to which it was screwed. Such an amplitude, was not only not necessary, it was not satisfactory, drops of mercury being thrown out of the cup by the platinum tip. The. Brass spring was discarded and another made whose natural period was about \y 2 times as great. This gave sufficient amplitude, about . 6 mm. , but the pitch of the vibrator rose about 12 vibrations per second when the change had been made. The first spring weighed i gram, the other .
