for ¥ =%.15 and for ¥ = 2.00, 1.40 (included for comparison 
with air) respectively. Comparative graphs (cf. fig. 10a, a', 
b, c) show that unless the shocks are very strong the limits 
of regular reflection for water-like substances are similar 
to those for ideal gases having corresponding values of tf 
and obeying the Rankine-Hugoniot adiabatic. 
The vanishing of the discriminant of equation (9) is
