Repovt of the Kew Committee. 507 



A brief summary of the performance of the chronometers is given in 

 Table III, Appendix III. 



During the year 21 chronometers have been entered for the Kew A 

 trial, of which 11 were certificated, 1 failed to pass, and 9 are still 

 under examination. 



VII. MISCELLANEOUS. 



Lens Testing. During the year 27 lenses have been tested ; of these 

 7 received class A and 20 class B certificates. Some of the 

 recent forms of Jena glass lenses have been under trial. With these 

 there appears to be a superposition of two curvatures in opposite 

 directions, one predominating near the centre, the other at the edge of 

 the field. The resultant curvature is generally unusually small near the 

 centre and over the greater portion of the field, but in some instances 

 at least it increases rapidly near the edge of the field, and special 

 attention should be paid to the size of stop to secure the best results. 



Paper. Prepared photographic paper has been procured and sup- 

 plied to the Observatories at Aberdeen, Oxford, Stonyhurst, Lisbon, 

 Mauritius, St. Petersburg, and through the Meteorological Office to 

 Batavia, Fort William and Valencia. 



Anemograph and rain sheets and sunshine cards have been supplied 

 to the Hong Kong and Mauritius Observatories, and blank forms for 

 the entry of magnetic observations to the Science and Art Depart- 

 ment, London, the India Office, the Jackson-Harmsworth Polar 

 Expedition, and Captain Lyons, R.E. 



Exhibition of Cloud Photographs. Some specimens of cloud and 

 other photographs and lantern slides were shown by the Committee 

 at the Royal Meteorological Society's Exhibition in April. 



Pendulum Observations. In December Mr. E. F. J. Love, of Mel- 

 bourne, at the request of Mr. Ellery, was given the use of the sextant 

 testing room for a few days for the purpose of swinging a set of 

 half -second pendulums on the spot where observations were taken by 

 Major von Sterneck in April, 1893. 



House, Grounds, and Path. The negotiations with Her Majesty's 

 Office of Woods and Forests, referred to in last year's Report, have 

 led to an increase of 5 acres in the area of the Old Deer Park leased 

 by the Committee. The new lease contained the condition that the 

 entire holding should be enclosed in a substantial fence. An oak 

 park paling has accordingly been erected at a cost of rather more 

 than 350. This expense, however, together with that of continuing 

 the existing roadway from Fuller's Grate, through the new holding, 

 has been wholly met by a gift of 400 made for the purpose by Mr. 

 F. Galton. 



Library. During the year the library has received publications 

 from
