MAIM' WHITNEY. 213 



mum was about 17°. This was higher than the average, 

 which Spoerer thinks is about 15°. Calling 1884.0 the 

 time of maximum, the mean latitude was about 12°. 



Spoerer holds that the last two maxima were too early. 

 This has been too late. He argues farther, from liis ta- 

 bles, that instead of this maximum being followed by a 

 correspondingly belated minimum, the next minimum 

 will follow in a period of time less than his mean, 6.5 

 years. 



Of the spot-period, whose maximum has recently 

 passed, we can, therefore, say : 1st, that it has produced 

 a smaller number of spots than the preceding ; 2d, that 

 the maximum has been later than the mean period 

 would place it ; and 3d, that the mean latitude attained 

 by the spots has been lower.
