lene was made at only three temperatures: — 15°.2, — 7°.l, and 0°.0, 

 with 16, 16, 16 points respectively. All of these points, with very few 

 exceptions, lay on smooth curves consistently to 0.001 inch. 



The results of the graphical computations of displacement and pres- 

 sure at equispaced points are shown in Table VL The displacement at
