To the Editor.
—The article by Miller et al1 concerning the cavum vergae errs in one detail: the authors use the terms cavum septum pellucidum and cavum velum interpositum for spaces properly called cavum septi pellucidi and cavum veli interpositi.If Coleridge2 were writing about his opium dream today, his "caves of ice" would probably be just "ice caves," and the meter of Kubla Khan would limp in consequence. With regard to the cava of the brain, also, it is better to be old-fashioned, go along with the Nomina Anatomica, show oneself to be "progenitive": they should be caves of "i's."
