The figs. 2, 3, 4 (Plate 8) represent the results of Table II. 
In the curve figure (2) the ordinates are the pressures, and the abscissae the arcs 
corresponding to 0. 
In the curve figure (3) the ordinates are the same plotted to absciss9e = H sin 6. 
In the curve figure (4) the horizontal ordinates are the same as the vertical ordi¬ 
nates in figs. 2 and 2, and the vertical abscissae are = B cos 9.
