1. The liver tissues in the 7 cases of the II & III types of so called catarrhal jaundice, the Vater's papillary region and the head region of pancreas in some of them are pathohistologically observed. 2. The 2 cases show the II type, the 4 cases show mostly the III type and show party the II type-picture, and the I case shows a combination form of both two types. 3. The cases, supposed to be caused by a obstruction of the intrahepatic bile excreation, Giving support to the theory of H. Eppinger, besides other cases supposed to be caused by a osmotic acceleration of peripheral bile ducts and leakage of bile etc without a remarkable obstruction of the bile excreation are observed in the II type. The obstructions of the Vater's papillary region are observed in all the cases of the III type. 4. The common pathologic changes in the blood and lymph vessels systems are observed on all of these cases. Therefore, it may be proper that the theory of the serous inflammation reported by H. Eppinger should be refered to the cause of them.
