the fissure, and then the cavo-surface angle bevelled, when the condi-
tions would be similar to those in the wall of an axial surface cavity,
and not as strong as the location requires. Not only is this true, but
it also leaves a vulnerable point next to the margin of the filling—
point of liability. Cutting just beyond the fissure, the wall nuiv be
left in the axial plane and have an ideally strong margin, and the
point of liability is removed. To state the conditions in general
