deduced with aluminium-bismuth-tin alloys corresponds with the 

 formula BiAl 10 . Applying Stokes' two methods, large-scale plottings 

 lead to the values A B = 8'2 and C + C' = lll'O for the first 

 method, and A+A' = 38'0, B+B' = 50'0 for the second method 

 whence the limiting point, L, corresponds to the composition
