A method is described which permits daily readings of the frog's systemic blood‐pressure to be made in light ancesthesia. Constriction of one or of both renal portal veins was performed in frogs ( Rana esculenta ) in which the abdominal vein had been ligated. The constriction had no effect on the systemic blood‐pressure. Obstruction of the aorta just above the origin of the renal arteries in Rana esculenta did not alter the frogs' blood‐pressure, neither did this operation do so in combination with constriction of the renal portal veins. Some of these experiments were done in the Molteno Institute for Parasitology. It is a pleasure to thank Professor Keilin for the facilities he gave me.
