It appears from these results that the calculation of Jt cannot 

 always be regarded as a good criterion of the variability being 

 regulated by the law of accidental events. From a series of 

 numbers, composed, as the barometric departures for Batavia are, of 

 groups which follow neither the simple normal law nor the more 

 complicated law (6), still the calculation of :t leads to a value which 

 is correct within I'/o
