Prof. Balfour Stewart and Mr. W. L. Carpenter. 



which of these are fitted to be subjects of comparison. This we now 

 proceed to do.* 



SS.^, TT_ S8 . All sufficiently good. Use for all -40, -30, 

 38, reduced to 39. 



SS.go, TT.sj. All sufficiently good. Use SS-31, 30, 29; 

 TT-34, -33,' -32 ; KT-34, -33, -32, all reduced to -33. 



SS.jg, TT_| 5 . Toronto too nearly single; all the others good. 



SS_ 8 , TT_ V Kew Inequality very small and irregular; the 

 others sufficiently good. 



SS+i, TT+ 3 . Kew Inequality presents two maxima and minima; 

 others good. 



SS +12 , TT +8 . Toronto Inequality too nearly single. Sun-spots 

 present also traces of two maxima ; Kew temperature good. 



SS +19 , KT +20 . Use for all +17, +18, +19; reduced to +18. 



SS +26 , TT +27 . Sun-spots two maxima; others sufficiently good. 



SS +S4) TT +S3 ". Use for all +32, +33, +34, reduced to +33. 



SS M , TTV Use SS + 43, +44, +45; TT + 39, +40, +41; 

 KT + 38, +39, +40, all reduced to +40. 



It thus appears that out of ten instances sun-spot Inequalities 



It will be desirable to exhibit the rejected inequalities. They are as follows, 

 being the aggregates for 36 years in S3 and TT and for 24 years in KT.
