 short grass. A number of spare thermometers are kept in 

 reserve. 



Bain Ganges, — The standard gauge is of copper, and is 

 5 inches in diameter. The height of the rim above sea-level 

 is 254 feet. One of Symon's storm rain gauges is employed 

 for the measurement of thunderstorm and other torrential 

 rains. During the last four years a Eichard self-registering 

 rain gauge has given a continuous record during eight months 

 of the year. It is taken indoors during the winter season, as 

 it is liable to sustain damage during frost. 



Sunshine. — A Campbell-Stokes sunshine recorder is em- 

 ployed for the determination of bright sunshine. Its position 

 has to be changed three times a year, in order that it may 

 have the benefit of a clear horizon. 



Wind. — A Robinson hemispherical cup anemometer is 

 placed on the top of a ladder erection 17 feet above the 

 ground. It is read daily at 9 a.m., except when snow or 

 hoar-frost has been deposited on the steps. When this is 

 the case no reading is made, as the risk in ascending is 

 considerable. 



Rainhand. — Observations of the thickness of the rainband 

 in the spectrum of sunlight have l)een made three or four 

 times daily during the last ten years. No observations are 

 made during the author's absence from home, as the work 

 cannot conveniently be handed over to the interim observer. 



I take this opportunity of acknowledging my indebted- 

 ness to Mr W. M. Mossman, who observes in my absence, 

 thus enabling an unbroken record to be maintained during 

 the past eleven years. 



Remarks on the Meteorology of 1897. 



January. — Cold, dry, and dull weather prevailed during 

 the whole month. The absolute maximum was 47°"0 on the 

 4th, there being only four Januarys during the last fifty-seven 

 with a lower absolute value. From the 9th till the end of 

 the month, frost was recorded nearly every night. During 

 this time the highest temperature recorded was 39°'8, on the
