Report of the Kew Committee. 



Meteorological Registers of the Observatory were searched from 1843 

 to the end of 1880, and an enumeration made of all the observations 

 of fog and mist recorded in them. The cost of the examination was 

 defrayed by the Council. 



Lost Journals. — On going through the books of the Observatory for 

 the purpose of compiling the above-mentioned tables, it was found 

 that the volumes containing observations made between January and 

 June 1845, and August 1848, and December 1853, were missing. 

 On making inquiry it was discovered that the volumes containing the 

 MSS. results for 1845 and 1849 to 1851 were in the library bequeathed 

 by the late Sir F. Ronalds to the Society of Telegraph Engineers and 

 Electricians, and the Council of that Society most courteously directed 

 these records to be restored to the custody of the Kew Committee, 

 which has been done. 



Further search has failed to bring to light any regular records of 

 observations made between April 1851, and January 1854 ; and it is 

 believed that none were made during the interval which elapsed 

 between the discontinuance of the system of observations organised 

 under the superintendence of Sir F. Ronalds and that established by 

 Mr. J. Welsh, after his own appointment as Superintendent. 



Complete specimen sets of curves from the various photographic 

 and autographic instruments in use at the Observatory have been 

 prepared and forwarded to the exhibitions of the 



Leeds Philosophical and Literary Society, 

 Yorkshire Fine Art and Industrial Institution, 

 Richmond Industrial and Fine Art Loan Exhibition, and the 

 International Photographic Exhibition at Vienna. 



At the latter exhibition a silver medal was awarded to the Com- 

 mittee for their exhibit. 



The Superintendent has, with the consent of the Committee, read 

 the following papers before the Meteorological Society, all of which 

 have been published in the " Quarterly Journal " of the Society : —

 Dryness of the Air, with Changes of Barometric Pressure at the Kew 

 Observatory," vol. vii, p. 49.

 Readings at the Kew Observatory during the ten years 1870-79,"
