76 Report of the Kew Committee. 



The number of instruments under observation has been increased 

 by the addition of a snow gauge on Prof essor Cipher's principle for the 

 purpose of measuring falls of snow, but no opportunity has occurred 

 since its erection of thoroughly testing its indications. 



A new 8-inch Glaisher gauge has been supplied by the Meteoro- 

 logical Office, and its readings observed regularly, since January, 

 with the view of substituting it for the old square 100-inch area 

 gauge hitherto employed for check upon the Beckley S.R. gauge, on 

 the completion of a full year's comparison of the two gauges. 



Seven months' observations have also been made of a second 8-inch 

 gauge, with the view of determining the effect ' of paint upon the 

 inner surface of the collecting funnel. 



During the period that the east room of the Observatory was under- 

 going alteration, the working standard barometer, Newman 34, was 

 temporarily removed to a position a few yards distant in the North 

 Hall. Comparisons were made with the Welsh standards (which were 

 carefully cased in, during the time of occupation of the room by 

 workmen), both before, subsequent to its removal, and after its replace- 

 ment in its old position. 



The following is a summary of the number of meteorological obser- 

 vations made during the past year : 



Readings of standard barometer 1 740 



dry and wet thermometers 3480 



,, maximum and minimum thermo- 

 meters 732 



,, radiation thermometers 1285 



,, rain gauges 1532 



. Cloud and weather observations 1882 



Measurements of barograph curves 8764 



,, dry bulb thermograph curves. . 9462 



,, wet bulb thermograph curves. . 8668 



,, wind (direction and velocity). . 17472 



,, rainfall curves 795 



sunshine traces 1891 



In compliance with a request made by the Meteorological Council 

 to the Committee, Mr. Whipple visited and inspected during his 

 vacation the Observatories at Aberdeen, Glasgow, Stony hurst, and 

 Oxford, as well as the anemographs at Swaiibister, North Shields and 

 Fleetwood. 



Mr. Baker also inspected the Falmouth and Valencia Observatories 

 as well as the Anemographs at Mountjoy Barracks (Dublin) and 

 Holyhead. 



Advantage was taken of these visits to fit Stonyhurst lifters to
