It has been observed in the dog that the decrease in intracarotid plasma calcium level elicits transient changes (hyperpnoea and apnoea) in the respiratory pattern. The phenomena appeared if the penetration of the introduced solution in the systemic circulation was prevented by a ligature of the common carotid trunk and/or if the solution could not reach the thyroid gland. No changes in the respiration occurred if the carotid and the remnants of the thyroid artery had been denervated. No change whatever occurred if the plasma calcium level was not influenced or the intervention had been performed on the femoral artery.
