Even this result taken singly might be merely accidental ; but 

 when the other steps in the same series show precisely similar 

 tendencies, the general tenor must be accepted as confirming the 

 indications given by the majority of the individual experiments. 



In comparing the produce of 2 oz. and 4 oz. sets, out of 12 

 experiments, the net results of 8 are in favour of the 4 oz, sets, 

 and 4 in favour of the 2 oz.
