A superficial examination reveals thepicture of an inflammatory process. A careful examination, however,shows that the cells are arranged in rows along the course of blood-vessels, which peculiar arrangement constitutes one of the most reliablediagnostic evidences of the character and variety of the tumor. Ifthese rows of cells are examined more carefully, it becomes evidentthat they are the product of connective-tissue proliferation. Veryfrequently short rows of four or five quadrangular cells are met with,densely packed, which are joined on the sides by triangular cells.The cells in such circumstances lose their round shape from mutualpressure. Round cells differ from spindle-cells in that the cell-seg-mentation by indirect division more speedily extends from the nucleusto the cell-proliferation. Mitotic fi
