1. Let S"(K) be a sphere-bundle f over a simplicial complex K. The v-sphere S"(p), associated with any point peK, is to have the metric of a hypersphere with unit radius in Euclidean metric space Rn (n= v-\-l). Two points on S"(p), distant\-n apart in S"(p), will be described as mutually orthogonal. By a normal m-fold projection (m^ n) in S"{K), of a sub-set
