Recently J. R. Rice Approximation of Functions, Elsevier Pub. Co. 1965, p. 111-133 initiated a geometrical study of non-linear approximations. This paper offers a small contribution to certain analytical aspects of mean- square non-linear approximations. One result is to exhibit a family of non- linear topological subspaces of the space Ca,b with the mean-square metric which has a local unique best approximation property.
