1. Adrenalin and pituitrin constrict the liver simultaneously with the rise in blood pressure when injected into the hepatic artery, portal or femoral vein.
2. Adrenalin dilates the liver during: (a) depressor responses in blood pressure, and (b) sometimes when pressor doses are given if the cat is in poor condition.
3. Histamine and peptone cause a diminution in liver volume which in case of histamine is probably an active contraction of the liver vessels.
4. An atypical response to histamine resulting in an increase in liver volume is discussed.
