26. Observations on the preceding experiments. 



(1.) I will first of all remark, that though the idea was to 

 hold the sieve in such a manner as to bear uniformly over the 

 whole board, there appears in most of the experiments a slight 

 tendency to greater concentration towards the centre, as is 

 shown by the horizontal and vertical summations which I have 

 added. This might have been probably corrected by such an 

 alteration as filling the sieve more completely ; but an exami- 

 nation of the contents of the squares, and the irregularities 

 marked by contiguous squares, show that this cause has but 

 slightly operated in producing the observed inequalities of 

 distribution. I conceive, then, that under the given conditions
