this way it can be shown that a water molecule at § T c 

 in the liquid state cousists on the average of two molecules of 

 the normal form H 2 0. The ratio for di-isopropyl in Table II., 

 it will be seen, does also not fit in very well with the remaining 

 liquids. This suggests that it is slightly polymerized.
