By virtue of recent remarkable advance in optical instruments as well as in photographic techniques it has become possible to observe precisely the details of liver surface morphology. Taking the advantage of such improvements we have established a new classifi cation of liver surface pictures with peritoneoscope. For the purpose to handle readily with numerical values, all the liver surface pictures taken by the aid of peritoneoscope are represented by numbers in three digits ; as some hundreds and some tens odd numbers. Those in hundreds are divided into 5 groups of 1.00 to 500 according to the elongation of Glisson's capsule and the manner of nodule formation ; and those in number expressed by tens are further divided into 3 subgroups according to the relation of the size of nodules to the inter-nodular space, of them ones whose nodules are in contact with on another and the size of nodules is less than 2 or 3 mm are placed in teens ; and those that are similarly in contact but their size is about 5 mm or more are put in the category of twenties ; and those whose inter-nodular space is big irrespective of the size are in thirties. As to the numbers in one digit they are classified into 8 groups: ones with diffuse white spots are given No. 1; those with arteriolar network, ' Kolliker's veins or lymph ducts No. 2 ; those with diffuse reddening, edmea No. 3 ; those with proliferation or hyperemia of arterioles No. 4 ; those with a few small recesses No. 5 ; those with many small recesses No. 6 ; with patches No. 7; and those with semi-spherical regeneration No. 8. A discussion was made on the relationship between our new classification and liver biopsy histological pictures.
