Membrane action potentials of bovine mesenteric lymphatics were recorded simultaneously with isometric contractions by use of the sucrose gap method. The action potentials always had one-to-one correspondence to the con traction waves. From the effects of tetrodotoxin, manganese, cal-calcium-free environment, and barium chloride on the spontaneous contractions, it was suggested that calcium current may probably play a major role in producing spike discharge in the smooth muscles. Blood capillaries were found within the smooth muscle layers as well as in the adventitia.
