ON MAGNETIC OBSERVATIONS AT FALMOUTH OBSERVATORY. 105 
3. Continuous records of pressure, temperature, wind, rain, &c., 
must still be the foundation of future progress in meteorology, and the 
existence of records over the long period of forty-three years is in itself 
a ground for their permanent maintenance. 
As regards Magnetic Work. 
4. The conjunction of Falmouth with Eskdalemuir for the effective 
representation of the details of the variation of terrestrial magnetic 
force. 
5. On account of the difference in latitude, the character of the dis- 
turbances recorded at the new Observatory at Eskdalemuir is more 
different than that at Falmouth from the accepted standards of Kew 
Observatory; therefore, owing to the similarity of latitude, the Fal- 
mouth records will be suitable in comparison with those at Kew Observa- 
tory for the investigation of secular change. 
6. The position of Falmouth is exceptionally favourable from the 
magnetic point of view, because it is on the coast in close proximity to 
the Atlantic Ocean, and therefore affords special facilities for making a 
connection between the land magnetic surveys and the ocean survey. 
This has been demonstrated by the visit of the ‘ Carnegie,’ the magnetic- 
survey ship of the Carnegie Institution of Washington, which for the 
purpose of such connection made Falmouth its first port of call. 
7. The problems of terrestrial magnetism, to the solution of which 
the observatory has contributed its records during the past twenty-four 
years, are still engaging the joint investigation of eminent physicists 
throughout the world. In this connection special data are frequently 
sought from and furnished by the Falmouth Observatory. 
8. Long before the Kew Observatory was affected by electric trams 
the Royal Society felt the importance of supporting the establishment of 
an additional observatory at Falmouth, by contributing the instruments- 
necessary for continuous photographic records, and for absolute observa- 
tions. 
9. The scientific value of and necessity for continuity of observa- 
tions. 
The Committee desire to express their regret that the difficulties in 
the way of continuing the magnetic observations which were begun in 
1887 have not been overcome. 
The Committee hope that, with a view to assisting the appeal for a 
Treasury Grant for the Falmouth Observatory, a resolution may be 
passed by Section A recommending that in the interests of science 
Falmouth Observatory may be efficiently maintained. 
Investigation of the Upper Atmosphere, in co-operation with a 
Committee of the Royal Meteorological Society.—Eleventh 
Report of the Committee, consisting of Dr. W. N. SHaw 
(Chairman), Mr. E. Goup (Secretary), Messrs. D. ARCHI- 
BALD, C. VERNON Boys, C. J. P. Cave, and W. H. Dives, 
Dr. R. T. GuAzeBprook, Sir JostpH LARMoR, Professor J. EH. 
PETAVEL, Dr. A. ScHUSTER, and Dr. W. Watson. 
MeetinGs of the Joint Committee were held in the rooms of the Royal 
Meteorological Society on October 18, 1911, and July 5, 1912. At 
the meeting in October it was decided to continue the ascents of 
registering balloons at Mungret College, Limerick, with the co-opera-
