80 REPORT—1905. 
The sunshine recorder on Ben Nevis for the nine months registered 
666 hours, or eighteen hours above the average of twenty years, whilst at 
Fort William the aggregate was 1,008 hours, or four hours more than the 
average of thirteen years. At both stations sunshine was very deficient 
in April and May, the former month having the smallest total on record. 
On the other hand, June, July, and September had amounts much above 
the average. 
The estimated cloud amounts compare in a satisfactory manner with 
the records of sunshine, the value being, for example, very high in April 
and low in June. 
Auroras were observed on January 23, February 8, May 6. 
St. Elmo’s Fire:—January 7, 14, 27; March 22; May 3, 17; 
June 20. 
Zodiacal Light :—March 9, 10. 
Thunder and Lightning :—February 12; May 1; July 31. 
Thunder only :—July 13; August 14. 
Lightning only :—January 10, 23, 28. 
Solar Halos :—February 1, 9 ; March 10 ; April 18 ; May 20 ; June 2, 
12 ; September 2. 
Lunar Halos :—February 28 ; March 1; August 25. 
Meteorological observations on Ben Nevis having now ceased, the 
object for which this Committee was appointed no longer exists. The 
Directors of the Observatories, however, have still a large and costly 
work before them. The double record of the High and Low Level 
Observations, the unique character of which has been pointed out in 
previous Reports of the Committee, has still to be discussed in its rela- 
tions to weather, and especially to those movements of the areas of high 
and low barometric pressure on which changes of weather mainly depend. 
The scientific and climatological discussion, so far as already carried out 
in respect to areas of high and low pressure, clearly indicates the import- 
ance of this double record in supplying data for the investigation of the 
causes of weather changes. 
The closure of the Observatories prevents their observations being 
made use of directly for weather forecasting, but the Committee con- 
fidently expects that the results of the discussion mentioned above will 
supply forecasters with new information in respect to changes of weather, 
and thus materially aid this important branch of practical meteorology. 
Magnetic Observations at Falmouth Observatory.—Report of the Com- 
mittee, consisting of Sir W. H. Preece (Chairman), Dr. R. T. 
GLAZEBROOK (Secretary), Professor W. G. Apams, Captain CrrEak, 
Mr. W. L. Fox, Principal Sir Arraur Ricker, and Professor 
A. ScHUSTER, appointed to co-operate with the Conmuattee of the 
Falmouth Observatory in their Magnetic Observations. 
THE grant voted by the Association last year has been expended in 
carrying on the magnetic observations at Falmouth Observatory. 
The results of the observations during 1904 have been published in 
the Annual Report of the National Physical Laboratory, and are very 
satisfactory. The vertical force curves have been measured for the first 
time, and the results for 1903 and 1904 are given in the Report.
