| Kithill Top | 942 | 1067 | The weather was very variable on this day, and the only correspondent observation by the sea side that I had was the arithmetical mean between two, made at the distance of several hours from the time of my observation on Kithill. I am therefore inclined to think, that the trigonometrical measurement in this instances most to be relied on. |

| St. Agnes' Becaon | 664 | 621 | In this instance, the simple |
| method, that is to say, the difference alone of the logarithms of numbers which express the heights of the barometer at each station (six hundred and sixteen feet), is more correct, or at least comes nearer to the trigonometrical measurement, than the method with the corrections. N. B. The comparative experiment on the sea shore, and on St. Agnew Beacon, were carefully made, there was avery short interval between each, and the observation were made in a line nearly vertical, between two and three o'clock, in the afternoon. | |||
