MR. AIRY’S ACCOUNT OF THE BARTON EXPERIMENT 
By the application of the numbers from these two tables, together with those for 
Arc and Barometer, in the same manner as in the Harton Experiments, there is 
obtained the “ Corrected Log. Rate of Pendulum upon Clock” referred to Barometer 
O’OOO and Thermometer 50° ; but affected by the full amount of the errors of the 
table for corrections depending on the Thermometer.

upon its Clock.
