1931 Cannon & Bacq. in Amer. Jrnl. Physiol. XCVI. 411 Because the substance is derived from structures under sympathetic control, when they are influenced by sympathetic impulses, we suggest that it be called sympathin.

1938 Nature 12 Feb. 266/2 The authors reject Bacq's rather factious criticisms of their theory of sympathins E and I.

1946 Nature 20 July 88/1 In Cannon's remaining active years he was largely concerned with evidence as to the nature of the sympathetic transmitter ‘sympathin’, which he believed to be not identical with adrenaline.

1971 Nature 2 Apr. 340/2 In an attempt to demonstrate this increase the transmitter ‘sympathin’ liberated from sympathetic nerve to the spleen was examined.
