1. Fine medullated fibres pass to the suprarenals almost wholly in the splanchnics; they have no intermediate ganglia in the abdominal cavity and are of spinal parasympathetic nature. 2. Stimulation of the greater splanchnic after application of nicotine to the cœliac ganglion causes marked dilatation of the suprarenal vessels. This is demonstrated both by histological observation and by measurement of the blood‐flow. This vasodilatation does not appear until the sympathetic nerve fibres are interrupted; it is brought about by means of the spinal parasympathetic fibres. It is not blocked even by a large dose of atropine. 3. The vagus seems not to play any significant part in the innervation of the suprarenal.
