N from column i. The result is mf for this key point. In the fourth 

 column headed A" are set down the numbers of the second-remove 

 points in order. These are used to obtain m" , m'" , w'^ in succession 

 according to equation (10) by means of the subsequent columns 

 headed +m" — , +w"' — , ■ • • , and the values previously obtained 

 in column m' for each second-remove point. 



The procedure is thus to set down the key, first-remove and second- 

 remove points in columns 2 and 4, then the values N in column i ; 

 compute tn' for every key point and use the values so obtained in 

 column 5 to get m" for each point; use these latter values to get m'" , 

 and these to get m^", and so on. The values actually obtained are
