Abstract
DR. JEFFREYS (NATURE, April 28, p. 267) claims that “experimental geometry” is a contradiction in terms. I protest vehemently. “Geometry” means the measurement of the earth.

It is “logical geometry” that is the contradiction in terms; it is that expression which has introduced all this confusion between logic and experiment; and it is the mathematicians, not the experimenters, who have stolen the word and perverted it from its proper meaning.
