1. Tactile stimulation of a forelimb grafted into the gill region in urodeles (Pleurodeles waltlii and Triturus vulgaris) yields no corneal reflex.

  2. If the foot of such a grafted limb has been cut off, stimulation of the resulting regeneration blastema evokes a corneal reflex in the same way as does stimulation of the cornea of an eye transplanted into this region.

  3. After complete regeneration of the foot the corneal reflex disappears, butJ. Embryol. exp. Morph. from a new regeneration blastema developing after a second and in some cases even after a third amputation the corneal reflex can again be elicited.

  4. These results are considered to be inconsistent with the ‘modulation theory’ of Weiss.
