Taking these ten plants whose times of flowering range 

 from April to June, it will be seen that the spring season of 

 1895 was, in Nova Scotia, nearly four (3.8) days in advance of 

 the average for the four years, while that of 1894 was nearly 

 two (1.8) days behind. But, dividing the spring season into 

 two divisions, before and after the middle of May, the first four 

 plants belong to early spring and the last six to late spring. 

 The average dates of blooming, and the differences from the 

 average of the four years, are shown in the following table : 



This means, that the early spring of 1892 was nearly a day, 

 (0.9), in advance of the average, but the late spring was retarded 

 nearly three (2.7) days. Was the latter part of May in 1892, 

 colder than the average ? And so forth with the other items.
