and developing the exponential,
1°. The coefficient of z is
q + ^ (fc — 2).
2°. The coefficient of z 2 is
iq 2 + q {ISi ~ i 0 - 3)} + ^ S 2 - \ (* ~ 3) Si + (k - 3) (¿/e - £),
and so on.
The peculiarity is the appearance of the factors k — 2, « — 3, &c. If we neglect
these terms, and consider as well q as a, b, c... to be each of them of the dimension
unity, the coefficients will be homogeneous.
