The temperature conditions of a longer period may be sum- 

 marised by adding the amounts of accumulated temperature 

 above 42 0 or below 42 0 of the individual weeks which compose

 are added. Cumulative values from the commencement of the 

 year to the end of each week, for each of the six elements, 

 number of rain-days, total rainfall in inches, accumulated tem- 

 perature above 42 0 , accumulated temperature below 42 0 , number 

 of hours of bright sunshine, and the percentage of possible dura- 

 tion of bright sunshine, are published in an annual appendix 

 to the Weekly Weather Report.
