depart from their type in two, Toronto Inequalities in two, and Kew 

 temperature Inequalities in two cases, leaving five unexceptionable 

 triplets for comparison. These are given in Table III (p. 307). 



In the preceding table the settings have been arranged by strictly 

 terrestrial considerations. If, therefore, there is no connexion between 

 terrestrial and solar Inequalities, the sun-spot maxima nhould be 

 distributed impartially up and down the table without any other than 

 chance grouping together. Their behaviour is, however, very dif- 

 ferent from this, these maxima being comparatively closely grouped 

 together about a position nine days later than that of the Toronto 

 temperature-range maxima which begin the table. 



The results of this table are exhibited in Diagram I which accom- 

 panies this paper.

 and well defined ; and, without attempting to prejudge the question
