Abstracts of the Makeestoun Observations, 1843. 
In order to avoid repetition, it may be remarked generally, — 
First, That the results for the month of January are more imperfect than those for the succeeding months, 
as on the first week of 1843 only four daily observations were made, and on the second week only eight. Attempts 
have been made to render the means comparable and as complete as possible, by means of observations made at all 
the 24 hours in 1844 : these will be found explained after the various Tables. 
Second, In obtaining the hourly means for the month of January the first week's observations were wholly 
rejected. 
Third, It is obvious that the daily means from the nine observations, whatever attempts at correction may 
have been made, are imperfect, and that the results deduced from these means cannot be expected to be so distinct 
as they would have been from twelve two-hourly observations. 
Fourth, As no observations were made on Sundays, the places which the means for Sundays would have 
occupied have been filled up by the means of the three preceding and three succeeding days ; these means are 
therefore weekly means, and may be considered as approximate means for the Sundays. They have been used in 
the summations having reference to the moon's position, as it was considered that the want of any means on these 
days would affect the accuracy of the results more seriously than the use of the approximations. 
Fifth, The time used in all the Tables is Gbttingen mean time astronomical reckoning ; but in the Remarks 
on the Tables, Makerstoun mean time civil reckoning is used, unless the reverse is stated ; thus 20 h in the Tables 
is equivalent to 7 h 10 m a.m. in the Remarks.
