Instruction in the use of meteorological instruments has been 

 afforded to the Rev. Clement Ley, Inspector of English Observing 

 Stations, and Mr. H. I. Bell. 



In compliance with a request made by the Meteorological Council to 

 the Kew Committee, the Observatories at Aberdeen, Armagh, Fal- 

 mouth, Glasgow, Stonyhurst, and Valencia, have been visited and 

 their instruments inspected by Mr. Whipple during his vacation. 



Mr. Baker, also in consequence of a request of the Meteorological 

 Council, visited Stonyhurst Observatory in January last, and re- 

 adjusted the thermograph, which had accidentally been deranged 

 during the frost. 



With the concurrence of the Meteorological Council, weekly abstracts 

 of the meteorological results have been regularly forwarded to and 

 published by the " Times,"* " Illustrated London News," " Mid- 

 Surrey Times," and " Torquay Directory," and meteorological data 

 have been supplied amongst others to the editor of " Symons' Monthly 

 Meteorological Magazine," Professor B. Stewart, Dr. Rowland, 

 Mr. Greaves, C.E., and the Institute of Mining Engineers. 



Copies of selected photographic curves have been made and supplied 

 to M. Mascart. 



JElectrograph. — This instrument has been in continuous action 

 through the year under the care of Mr. Constable. 



It was found necessary in August to dismount and clean the in- 

 strument in order to restore its power of keeping a full charge of elec- 

 tricity, which had become somewhat impaired. 



On consideration it was deemed inadvisable to alter the bifilar sus- 

 pension as suggested in last year's report, but the Mascart insulating- 

 stands were fixed for the support of the water-dropping cistern, and 

 the action of the instrument has been greatly improved by their 

 adoption, so that strong charges of electricity are now registered even 

 in the dampest weather. 



Some trouble was experienced in maintaining a constant flow of 

 water from the jet during the severe frosts of last winter, but it was 

 not considered necessary to make special arrangements for heating the 



* A detailed investigation was made in the month of J an aary into the accuracy 

 of the weekly meteorological records published in " The Times." The result on the 

 'whole was very favourable, the principal difference being found in the rainfall, whieh 

 is usually given in excess of the true amount.
