272 RESULTS OF THE METEOROLOaiCAL OBSERVATIONS TAKEN DURING 



MAXiMnM Readings in Sun — continued. 



The excess over the shade maxima was 81°'5 in Spring, 74°*8 in Summer, 32°'4 in 

 Autumn, and 20° '4 in Winter. The intensity of solar radiation is thus at a maximum 

 in Spring and at a minimum in Winter. It was frequently noticed that on days 

 characterised hy high solar temperatures in Spring and Summer the maximum was 

 recorded before noon, while in most cases the shade maxima were recorded after 

 noon. The greatest excess was 94°"2 in November and the least 7°'6 in June, but in 

 the Winter season the total sunshine is much reduced owing to hills to the north, so 

 that had there been a clear horizon the values for this season would have been con- 

 siderably increased.
