Reference. 



No readings of the 

 barometer were 

 taken on Sundays, 

 or holidays, but the 

 missing values have 

 been interpolated. 



Blanks occur once or 

 twice. 



The values given are 

 monthly means and 

 extremes. 



These are the read- 

 ings taken at the 

 stations of the Scot. 

 Met. Soc, and ex- 

 tracted from the 

 schedules in the 

 Met. Office, Edin. 



In addition to the 

 ordinary observa- 

 tions automatic 

 instruments record 

 the fluctuations of 

 pressure, temp., 

 humidity, rain, and 

 sunshine. 



This is a very valu- 

 able rain register 

 kept for nearly half 

 a century. With 

 this exception no 

 registers of rain 

 only have been 

 quoted, but the 

 results of all these 

 extra •tations will 

 be given in Part II.

The present paper deals with mean values of the climatic elements for each day 

 of the year, it being quite evident that many of the most interesting features of the 

 pressure and other curves are wholly eliminated when monthly means alone are under 

 consideration. The data, wherever possible, have been calculated for the fifty years 

 1840-51 and 1857-94, the means in a number of cases being thus made comparable 

 inter se. The daily instrumental observations, being incomplete during the period 

 1852-56, could not be dealt with in this inquiry, but monthly means are available, 

 so that there will be no hiatus when we come to the examination of monthly and 

 annual averages. As regards the non-instrumental observations, which extend back 

 without a break to the year 1770, daily values for the fifty years quoted above have not 

 been given, but five-day totals will be found in Table XXXII. , which are graphically 

 shown for both periods in Plate III. It is not our intention to make any reference to 

 the monthly means deduced from the daily values extending over periods ranging from 

 30 to 125 years, as tables of monthly and annual values will subsequently be available, 

 based in most cases on observations extending over 132 years, particulars of which 

 will be given in the second part of this inquiry. 



* Since the above table was compiled, Mr G. J. Symons, F.R.S., has drawn my attention to a daily register of 

 pressure and temperature kept at Edinburgh from 1847-51 by Kenneth M'Kenzie. See Quart. Jour, of Agriculture, 

 July 1852, and Farmers' Note Book, No. xxvi. p. 402.
