Summary1 In chickens anaesthetized with sodium pentobarbitone, stimulation of a vagus nerve produced contractions in the muscles in the pre‐crop oesophagus which were only partly antagonized by hyoscine. 2 The effect of hyoscine in an isolated preparation of chicken oesophagus responding to nerve stimulation was shown previously to be similar to that now found in the in vivo preparation.
