We consider the linear space of composite fields as an infinite dimensional vector bundle over the theory space whose coordinates are simply the parameters of a renormalized field theory. We discuss a geometrical expression for the short distance singularities of the composite fields in terms of beta functions, anomalous dimensions, and a connection. (Based upon a talk given at the International Colloquim on Modern Quantum Field Theory, 5--11 January 1994, Bombay, India.)
