caption[Two numerical solutions]{(a) Numerical solutions for the small-time system 
with a constant-curvature body shape showing the scaled leading-order veritcal 
reaction force $N_0$ versus the scaled body mass $M$ for various values of $g$. 
Again, $I=M$ for definiteness and $A=0.7$. (b) As for (a) but over a wider range of 
values of $M,I$.}
