  The recent identification of a time and temperature dependent spin glass
correlation length, $\xi({t_w},T)$, has consequences for samples of finite
size. Qualitative arguments are given on this basis for departures from t/{t_w}
scaling for the time decay of the thermoremanent magnetization,
{M_{TRM}}(t,{t_w},T), where t is the measurement time after a ``waiting time''
t_w, and for the imaginary part of the ac susceptibility,
${\chi^{{\prime}{\prime}}}(\omega,t)$. Consistency is obtained for a more rapid
decay of $M_{TRM}(t,{t_w},T)$ with increasing t_w when plotted as a function of
t/{t_w}, for the deviation of the characteristic time for {M_{TRM}}(t,{t_w},T)
from a linear dependence upon H^2 at larger values of H, and for the deviation
of the decay of ${\chi^{{\prime}{\prime}}}(\omega,t)$ from $\omega t$ scaling
upon a change in magnetic field at large values of $\omega t$. These departures
from scaling can, in principle, be used to extract the particle size
distribution for a given spin glass sample.
