The correction for temperature was found by Professor Mayer by counting
the sound-beats between the standard and another Ut₃ fork, at different
temperatures. His result is +.012 vibrations per second for a diminution
of 1° Fahr. Using the same method, I arrived at the result +.0125.
Adopted +.012.

In the following table the first column gives the date, the second gives
the total number of seconds, the third gives the result uncorrected for
temperature, the fourth gives the temperature (centigrade), the fifth
gives the final result, and the sixth the difference between the greatest
and least values obtained in the several determinations for intervals of
ten seconds:
