This study was conducted to observe the condition of the ramification of the bronchus and pulmonary blood vascular system by injection of vinylite into the bronchial tree and pulmonary blood vessels in normal adult swines. The results obtained were summarized as follows. 1. Lungs of swine were composed of the same pulmonary territories as in lungs of human and dog. 2. Bronchial tree of swine also were axial divergency in the patterns. 3. Ramification of the left and right apical lobes are especially complex patterns but cardiac and diaphragmatic lobes are a little monotonous. 4. Intermediate lobe corresponding to mediobasalis branch of human lungs formed only one lobe in swine lung. 5. Pulmonary artery of right apical lobe was mono branch form in all case by authors observation. 6. $B._2$ streched into the seg. dorsalis of the right apical lobe was especially developed compare to $B._1$, $B._3$ of the seg, apicalis and seg, ventralis.
