By employing the vinylite and neoprene latex corrosion technique, the ramification and arrangement of A. renalis were observed in fifty adult dogs (100 kidneys). Obtained results were as follows: 1. In the dog a single renal artery arosed on each side from abdominal aorta in 99% and double renal arteries in 1%, a single bifurcated into the ramus dorsalis and ramps ventralis from which 2-6 segmental arteries originated. 2. The dorsal ventral planes of the kidney were divided separately into 3-6 vascular segments by the segmental artery into the parenchyma. Of them four segments were mostly frequent (in 73% of right kidney and 72% of left). 3. The ramifying method of the segmental artery from the ramus dorsalis et ventralis was divided 3 types and 12 kinds. 4. In 30 of 100 kidneys, either dorsal or ventral plane of a kidney was supplied from interlobar or segmental arteries belonging to the opposite ramps. In 29 of them, the dorsal plane was supplied from the ventral ramus. 5. Six right and 11 left kidneys had a common segment in the Extremitas cranialis of the kidney.
