{Physical isomerism} (Chem.), the condition or relation of
   certain (metameric) substances, which, while chemically
   identical (in that they have the same composition, the
   same molecular weights, and the same ultimate
   constitution), are yet physically different, as in their
   action on polarized light, as dextro- and l[ae]vo-tartaric
   acids. In such compounds there is usually at least one
   unsymmetrical carbon atom. See {Unsymmetrical}.
