 Summary of Weekly Means. 



I. Maxivia. 



Generally speaking, the maxima at Whitworth Park ate 

 higher than the corresponding readings at Oldham Road, 

 the daily average for the period in question at the former 

 observatory being 4i°'4, and at the latter 40°-2. In this 

 connection it may be noted that during the month of January 

 i/hrs. 2omin. of bright sunshine were registered at Whit- 

 worth Park, as compared with lohrs. 45mins. during the 

 corresponding period at Oldham Road, although it must 

 be pointed out that for January there does not appear to 

 be any connection between the differences in the maxima 

 and the differences in the amount of bright sunshine on 

 a given day. The greatest divergence — 8° -8 — between the 

 maxima occurs on Jan. 5th.
