Abstract
The responses of the whole glossopharyngeal nerve of the toad to inorganic and organic acids were markedly enhanced by the addition of univalent chloride and calcium chloride. The ratios of response of mixtures to the sum of respective responses of M/512 acids and M/4 chlorides were 1.2-2.7. The facilitatory effect of sodium chloride on responses to M/512 hydrochloric acid and acetic acid was observed in concentration of M/16 and the facilitation appeared in the concentration of the salt.
