MAGNETIC OBSERVATIONS AT FALMOUTH OBSERVATORY. 37 
The Committee learn that the progress of the magnetic work at 
Eskdalemuir has been further delayed owing to troubles with the under- 
ground chamber and the magnetographs, so that no opportunity has 
yet arisen for comparing the regular diurnal inequalities of the magnetic 
elements obtained at that station with those obtained in the South of 
England. For such a comparison records from Falmouth are iikely 
to be of especial importance. Believing that the continued mainten- 
ance of magnetic work at Falmouth in full efficiency is highly desirable, 
the Committee ask for reappointment with a grant of 501. 
Geodetic Arc in Africa.—Report of the Committee, consisting of 
Sir GEORGE DaRwIn (Chairman), Sir Davip Ginn (Secretary), 
Colonel C. F. CLosk, and Sir GrorGE GOLDIE, appointed to 
carry out a further portion of the Geodetic Are of Meridian 
North of Lake Tanganyika. 
1. The measurement was commenced in March 1908 and completed in 
February 1909. The arc extends from 1° 10’ N. to 1° 10’ S., i.e., the 
length is 24 degrees, or about 165 miles. 
2. One base, length eleven miles, was measured in the northern por- 
tion, in the Semliki Valley. The chain consists of one complex figure, 
three quadrilaterals, and one tetragon. 
3. All the stations have been marked in a permanent manner, and the 
Government of Uganda has been notified of their positions. 
4. The probable error of an observed angle is about 0.4”. 
5. Three azimuths and fourteen latitudes were observed. 
- 6. Magnetic observations for declination and dip were made at twenty 
stations. 
7. The work was organised by Major Bright, C.M.G., and carried 
out by a British party consisting of Captain Jack, R.E., Mr. McCaw, 
Mr. C. Chevallier, Lance-Corporal Jones, R.E., Lance-Corporal Page, 
R.E., and for a portion of the time Captain S. Iredell, 4th Battalion 
King’s African Rifles, who also commanded the escort. 
The Belgian party consisted of Captain Wangermée and Dr. Dehalu. 
Investigation of the Upper Atmosphere by means of Kites in co- 
operation with a Committee of the Royal Meteorological 
Society.—Highth Report of the Committee, consisting of 
Dr. W. N. SHaw (Chairman), Mr. W. H. Dines (Secretary), 
Mr. D, ArcuipaLp, Mr. C. Vernon Boys, Dr. R. T. Guaze- 
BROOK, Dr. H. R. Mutu, Professor J. E. Peravet, Professor 
A. ScuusTer, and Dr. W. Warson. (Drawn up by the 
Secretary). 
A MEETING was held in the rooms of the Royal Meteorological Society 
in November, at which it was decided that observations with pilot 
balloons should be made in Barbados, and Mr. Cave, who stated that 
he was going to Barbados, was asked to make the necessary arrange- 
ments, which he agreed to do. 
Mr. Cave was prevented from going as he had intended, and in con- 
Sequence the observations were not inaugurated, but the necessary
