Observations upon phagocytosis carried out by means of melanin to ascertain more particularly whether the opsonic index is identical with the hæmophagocytic index

Abstract

The following work was taken up in the belief that interesting information might be obtained by the substitution of a finely divided inert substance in place of bacteria, wherewith to study the phagocytic index in particular infective diseases. The substance which we selected was melanin obtained from the eye of the ox. The questions which we set ourselves to test by this method we may put seriatim ; and we may, after each, recount the particular observations bearing upon it, and give the conclusions to be drawn from them.
