from The Century Dictionary.

• In geometry: Pertaining to the projective methods of Monge.
• Not containing the idea of quantity or measurement.
• Containing description; serving or aiming to describe; having the quality of representing: as, a descriptive diagram; a descriptive narration.
• Milit., a short military history of each enlisted man, with a description of his person, and an abstract of his account with the government.
• in geometry, usually defined to be a property or proposition which can be stated without introducing the idea of magnitude. But it would be better to say that it is a property or proposition which relates to the incidence or coincidence of points, lines, and other geometrical elements, in general, or that it is one which does not depend upon the particular system of measurement adopted. Thus, the proposition that two triangles are equal if a side and two angles of the one are equal to the corresponding side and angles of the other, may be regarded as descriptive; while the proposition that through any point in space a single parallel to a given line can be drawn, is indisputably metrical, not descriptive.
