Results obtained by use of equation (142) are exceedingly rough, 
not only because of the exponential approximation but because 
of the large uncertainty in the exponent of R. Values are quoted 
in Table III to one significant figure. 
13.5 It is apparent from Table III that the observed energy 
loss over the interval considered is approximately accounted for 
by the sum of the estimated viscous and shock front dissipations, 
if it is assumed that one may correctly use the shock dissipation 
results for waves having rise times of the order of 10 to 20 
microseconds, Furthermore, it is apparent that the predicted losses 
are such that one would not expect to observe significant depart- 
ures (relative to the present experimental precision) from 
similarity scaling of the energy flux out to values of w/3/R 
of the order of 1074.
