Exactly solved lattice models: from polymer networks to an Ising model in a magnetic field

Some recent developments in the study of exactly solved lattice models in statistical mechanics are briefly reviewed. These include work with Debbie Bennett-Wood and Aleks Owczarek on polymers at surfaces (cond-mat/9805148) and with Katherine Seaton on the calculation of correlation lengths and the E_8 mass spectrum of the dilute A_3 lattice model (hep-th/9712121).
