  Exploiting an approach due to Singh and Fisher I show that in the high
dimension limit the ordering temperature of near neighbour Ising Spin Glasses
drops linearly with the kurtosis of the interaction distribution, in excellent
agreement with accurate high temperature series data of Daboul, Chang and
Aharony. At lower dimensions the linear relation no longer applies strictly but
the kurtosis can still be taken to be an appropriate parameter for ranking
different systems. I also compare the series estimates with simulation and
Migdal-Kadanoff estimates where these are available.
