✦ Synopsis

Orr and Watson ('13) presented evidence that carbon dioxide exerts an inhibitory effect causing apnea or slowing of respiration in the duck. On the other hand this gas causes respiratory acceleration when it acts through the allantois of the unhatched duck and not until the lungs take in air does the inhibition become manifested (Windle and Nelson, '38). It was inferred that newly functioning inhibitory lung receptors come into play to prevent the carbon dioxide accelerating action in the air breathing unhatched ducks. Experiments were planned to determine the relationship of the vagus nerves to the phenomenon in question.
