XXVII.—Report on the Hourly Meteorological Register kept at Leith Fort in the Years 1826 and 1827

Published online by Cambridge University Press:  17 January 2013

Extract

Having already published in the Transactions a detailed report on the Hourly Meteorological Register kept at Leith Fort, at the expense of the Society, during the years 1824 and 1825, it is unnecessary to enter into any recapitulation respecting the origin and history of this class of observations.

The singular and unexpected results obtained from these Registers, and the rapid approximation to general laws which some of these results exhibited, attached a great interest to the observations of future years; and it is satisfactory to find that the results for the two following years of 1826 and 1827 are almost perfectly coincident with those for 1824 and 1825, not only in their general relations, but even in their numerical laws.

page 358 note * The extraordinary character of the October curve in 1827 requires to be explained. When the daily schedules for that month were sent to me from Leith Fort, I was surprised to find two for the same day of October with very different numbers. Upon inquiring into the cause, I found that some of the non-commissioned officers who had voluntarily undertaken the duty of observing the thermometer, and for doing which they were liberally paid, had neglected to make the observations, and had filled up the daily schedules with false numbers. It is obvious from the curve that this fraud was committed by the person who made the afternoon and evening observations.

It is interesting to observe how little effect these erroneous observations have had upon the general results for 1827, when compared with those of other years.
