440 Dr. Moll’s account of the experiments on 
AUAK = 72 37 2,96 
AKU=58 12 36,07 
A U K = 49 10 20,97 
By these data A K is found equal to 17425,4 metres, the dis- 
tance from Amersfoort to Kooltjesberg. 
In the A K B A, we have A K = 17425,4 metres. 
L K B A = 79 47 16,1 
A. B A K = 93 45 7 
l_ A K B = 6 28 57 ,5 
180 1 20,6 
Thus, K B A = 79 46 49,2 
B A K = 93 44 40,2 
A KB™ 6 28 30,6 
With these data calculating BK, we have the distance be- 
tween both stations 17668,55. 
By these four different methods of calculation we have 
the distance between the two points when the observations 
were made, viz. from Kooltjesberg to Zevenboompjes.
