The outstanding feature, however, is the possibility that the velocity-distance relation may represent the de Sitter effect, and hence that numerical data may be introduced into discussions of the general curvature of space.

I knew that even if I were second or third rate, it was astronomy that mattered.

The universe is unfolding as it should.

There we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial.

Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.
