ABSTRACT Beadle & Booth’s work on grafting oral cones into reconstitution masses of Cordylophora lacustris has been repeated, confirmed and extended. Oral cone grafts induce the development from mass tissue of hydranth regions basal to the oral cone, and other regeneration of the mass is inhibited. ... a mass is not peculiar to the oral cone but is a property of all tissue with ... hydranth regions and outgrowth tips normally regenerate oral cones out of graft tissue, but induction may occur even when no oral cone is regenerated by the graft. Tentacle grafts do ...

The latter two types have only been found as typical elements in minnow ( ... laevis) retinae. The constituent parts of a multiple cone may differ from each other in staining properties ... size. A regular arrangement of single and double cones is a feature of many teleost retinae, but these cone patterns are only associated with equal double cones. Changes in the cone patterns occur during growth of the retinae. In ...
