If one looks up the literature on rumination in infancy, he receives the impression that the condition is an extremely rare one, not only because of the paucity of reports, but also because of the extensive way in which single cases are treated, and the discussion of them.
So far as I have been able to find, the first mention of rumination in infancy, aside from the very cursory remarks in textbooks, is the report of Freund1 in 1903. He speaks of a small number of cases of rumination, which he regards as closely related to pylorospasm. There is no definite report of single cases in his article. Since then there have appeared in the literature reports of cases by Maas,2 Finkelstein,3 Pouliot and Moricheau-Beauchant,4 Wirtz,5 Mayerhofer,6 Sluka.7 Lust,8 Brüning,9 Huldschinsky,10 Aschenheim,11 Lehnerdt,12 Schippers,13 Wanietschek,14 and
