The usual scaling equations at a phase transition, employed out of their usual validity range, with Tc a negative constant, fit properties observed in correlated electron systems with unmatched accuracy. We illustrate this behavior with our data in Ce(Ru1-xRhx)2Si2 for x= 0.4 and 0.5 and comment these results and what they imply physically.
