Paul (1896) has shown that the membrane was composed of flat epi-thelial cells. These could come from no other source than some part ofthe enamel-organ, probably from the outer tunic. Paul suggests that itsfunction is to protect the enamel from the action of acids. C. S. Tomes,who formerly held the view of his father, now agrees substantially withPaul.
