The last column in each of the above two tables contains 

 the velocities of solidification in the same tubes obtained by 

 interpolation from observations on the velocity at a number 

 of temperatures. The velocity was determined by measuring 

 the time taken by the boundary to pass between two marks 

 on the tube at a known distance apart. The following results 

 were obtained with the same two tubes: —
