REPORT OF THE KEW COMMITTEE. XXXi1x 
Report of the Kew Committee of the British Association for the 
Advancement of Science for 1867-68. 
The Committee of the Kew Observatory submit to the Council of the British 
Association the following statement of their proceedings during the past 
ear :— 
: The Meteorological Office, to which allusion was made in the last Report, 
continues in operation, Kew being the Central Observatory as arranged with 
the Meteorological Committee appointed by the Council of the Royal Society 
In consequence of this arrangement there has been during the past year a con- 
siderable access of work to the Kew Observatory, and the duties undertaken 
by that establishment may, as in the last Report, for clearness’ sake, be again 
considered under the two following heads :— 
(A) The work done by the Kew Observatory under the Direction of the 
British Association. 
(B) That done at Kew as the Central Observatory of the Meteorological 
Committee. 
This system of division will therefore be adopted in this Report; but it 
ought to be mentioned that the financial statement appended to it refers only 
to the first of these divisions, since the work done at Kew for the Meteoro- 
logical Committee has been paid from funds supplied by the Committee, and 
not in any way from money subscribed by the British Association.

1. New Instruments for Colaba Observatory.—The Chairman of the Kew 
Committee, shortly after the Meeting at Dundee, received a communication 
from Mr. Chambers, the Superintendent of the Colaba Observatory, Bombay, 
requesting the support of the Kew Committee in his application to the India 
Board for a supply of Self-recording Magnetographs and other instruments 
required for his observatory. This was ultimately brought before the Council 
of the British Association ; and in consequence of the steps taken, Sir Stafford 
Northcote, in a letter to General Sabine, dated 30 January, 1868, sanctioned 
the supply of new instruments for the observatory at Bombay, while General 
Sabine, on behalf of the Kew Committee, undertook to select the following 
instruments required :— 
(1) A set of Self-recording Magnetometers for registering by photo- 
graphy changes of Declination, Horizontal Force, and Vertical 
Force. 
(2) Thomson’s Electrometer, arranged for photographic self-registration. 
(3) A Self-recording Barograph and Thermograph, of the pattern 
adopted by the Meteorological Committee (added afterwards). 
(4) Apparatus for measuring and tabulating the curves given by the 
above-named instruments. 
(5) Photographic apparatus, porcelain dishes, and boxes for paper and 
photograms. 
(6) Moffat’s Ozonometer, in box with clockwork and rotating cylinder. 
(7) Beam-compasses, with steel points and tangent screw adjustment to 
measure 4 feet (for verification of distances in deflection experi- 
ments). 
(8) Rotating frame with large glass jar for testing thermometers. 
2. Magnetic work.—The Self-recording Magnetographs, ordered by the
