+Abrupt phase transitions, such as the jump in magnetization in the Ising
+model below $T_c$, are known to imply essential singularities in the free
+energy that are usually thought to be unobservable in practice. We have
+argued that this essential singularity controls the universal scaling
+behavior near continuous phase transitions, and have derived an explicit
+analytical form for the singularity in the free energy, magnetization,
+and susceptibility for the Ising model. We have developed a Wolff algorithm 
+for the Ising model in a field, and showed that incorporating our singularity
+into the scaling function gives good convergence to the simulations in \twodee.
+
+Our results should allow improved high-precision functional forms for the free
+energy~\cite{CaselleXXX}, and should have implications for the scaling
+of correlation functions~\cite{YJXXX,XXX}. Our methods might be generalized
+to predict similar singularities in systems where nucleation and metastability
+are proximate to continuous phase transitions, such as 2D superfluid
+transitions~\cite{ALHN}, the melting of 2D crystals~\cite{XXX}, and
+freezing transitions in glasses, spin glasses, and other disordered systems.
