All the ducks responded to the inhalation of a few breaths of 100% O<jats:sub>2<\/jats:sub> with a fall in <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub> of between 11 and 17% of control, and to the reduction in <jats:italic>P<\/jats:italic><jats:sub>a, O2<\/jats:sub> from control levels (93\u2013101 mm Hg) to 38\u201347 mm Hg with an average increase in <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub> of 190% of control which was potentiated by raising the level of CO<jats:sub>2<\/jats:sub>.<\/jats:p><jats:p>3. Ventilation approximately doubled when <jats:italic>P<\/jats:italic><jats:sub>a<\/jats:sub>, CO<jats:sub>2<\/jats:sub> was raised to 55 mm Hg, the greatest sensitivity to changes in <jats:italic>P<\/jats:italic><jats:sub>a<\/jats:sub>, CO<jats:sub>2<\/jats:sub> being over the range 40\u201345 mm Hg.<\/jats:p><jats:p>4. Carotid body denervation was carried out in nine ducks and the respiratory responses were modified. The fall in <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub> with inhalation of 100% O<jats:sub>2<\/jats:sub> was abolished in all ducks and the rise in <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub> with hypoxia was abolished in six.
