The source that Eccles referred to was a lecture published by Dale incalled Pharmacology and nerve endingsdescribing some of the early vassomotor into the physiology of neurotransmission.

I drew, revised and revised for remembering life cycles. The resulting ambiguity in the initial statements led to some confusion in the literature about the precise meaning dalew the principle.
