A much simpler procedure is the insertion of a "vitallium" tube into the bony lacrimal duct through the lower part of the sac, as advocated by Muldoon.1

It is free from chemical and electrolytic activities in human serum and when buried in human tissue does not produce any of the inflammatory reactions of other metallic foreign bodies.2 It is used chiefly
