HIXRICHS— ATOMIC WEIGHT OF VANADIUM.

Thus the least deviation or departure has resuhed from the use 

 of the ^Method 311 recently introduced by Edgar F. Smith. The 

 preHminary work of Berzehus, done eighty years ago, according to 

 methods a and b as represented by Hnes D and T on the diagram, 

 showed departures for sulphur and barium extending beyond the 

 limit of our diagram: 470 to the left (negative) in line D and 

 776 to the right (positive) in line T; the former is almost half a 

 unit, the latter three quarters of a unit of atomic weight.
