If from Ta 68°6 we subtract Ti 25, the remainder is 48°6, 44

ion from V 68°8 we subtract Ti 25 the remainder is 43°8, 44 
Tt "Tf from W 92 we subtract Mo 48 the remainder is 44 exactly. 
If from W 92 we subtract Nb 48:82 the remainder is 43°18. 
If to Te 64 we add Ti 25 the sum 89 is twice 44 nearly. 
If to Te 64 we add Ta 68 the sum 182°6 is three times 44 
ray nearly. 
to To 64 we add V 68:8 the sum 132°8 is three times 44

If the equivalent of Sn=59 be multiplied by $ the result is 
44-25, in other words 8Sn=444'25. 
If we add Sn 59, a 68°6, W 92, Vv 68°8 and Te 64, the result 
is 852°4, 8x44=35

If we add Ta 686, Mo 48, Sn 59, we have 175° 6, 44x4=176, 
If we add W 92, 2Te 128, we have 220, 5x44=220. 
If we add Ta 686, — 48, 2Sn 118, Vv 68°8, Nb 48: 82, we
