The histamine content of the tumor and various organs of a mouse with a transplantable mastocytoma was determined according to the spectrofluorometric method of assay. The tumor was located to the mesentery. The histamine content of the tumor was 11.797 mg per g dried and defatted tumor tissue, an extremely high value. The investigated skin from the back was also rich in histamine, while the histamine content was not found high in the other organs investigated, i.e. liver, spleen, and ovary.
