The sunshine value for the kingdom, after having steadily risen week after week, until 422 hours for ten weeks was attained 

 has for the above period fallen to 398 hours ; the maximum period of sunshine for 1888 is therefore past. The excess of, 

 rainfall has now attained an inch and a quarter for the kingdom, its distribution being much more equal ; temperature 

 for the kingdom has fallen from 2 deg. below the normal in last week's report, to 2-4 deg. below.
