the symmetrical types when s = 2, these types presenting special interest in relation 

 to the diurnal and semi-diurnal forced tides. The annexed tables give the values of 

 the computed roots, together with the corresponding periods of free oscillation for 

 the four depths of 7260, 14,520, 29,040, 58,080 feet treated of in Part I., corre- 

 sponding to the values -f$, --$, -fa, and for
