For any poset P let J(P) denote the complete lattice of order ideals in P. J(P) is a contravariant functor in P. Any order-reversing map f: P-+Q can be regarded as an isotone (= order-preserving) map of either P\* into Q or P into Q\*. The induced map of J(Q) to J(P\*) (resp. J(Q\*) into J(P)) will

## Note on the Homotopy Type of Mapping Cones" PETER HILTON I n [2] and [3] we proved certain theorems about the semi-group of homotopy types of based spaces where the composition operation is just the disjoint union with identification of base points. These results were suggested by certain obse
