In article <BtyBLw.42q@dcs.glasgow.ac.uk> areid@dcs.glasgow.ac.uk (Alastair Reid) described an idea for avoiding the paradoxes associated with empty carriers for many-sorted algebras, and I posted a reply describing the constructivists' technique of attaching finite sets of variables to equations or sequents. I said that I didn't know of a reference for the technique, but I've now found that it is described quite straightforwardly in Lambek and Scott's book "Introduction to Higher Order Categorical Logic", section II.1. In their historical comments, they attribute it to Mostowski (1951). Steve Vickers
