I point out that the results of a recent vapor pressure isotherm study of noble gas monolayers physisorbed on several lamellar halides by Millot, Larher, and Tessier can be explained in terms of an incipient triple point in some of the films and the usual liquid–gas critical point in others, whereas a critical point in all of the films is not in agreement with model calculations. Lamellar halides would thus provide a system in which the crossover, presumably via a critical endpoint, between the two cases can be studied experimentally.
