In paper 6473A (S8) (see ibid., vol.136, no.2, p.49-54, 1989) Vourdas and Binns attempted to illustrate how formal structures of algebraic topology describe topological aspects of boundary-value problems in three-dimensional magnetoquasistatics. Several shortcomings of the paper were pointed out by Bossavit in the correspondence 6819A (see ibid., vol.136, no.5, p.260-1, 1989). The author of this article elaborates on these comments because he feels they have important consequences which did not seem to be appreciated by the authors in their response to Bossavit.
