Thegummatous formation shows at a glance its character-istic ; it appears, contrasted with the tubercle, as a nodulethrust into the midst of the straight tubes of the cone,.

A tubercle,under the same conditions, seems not so much to overrunthe tissue by crowding, but to lead to degeneration ofthe tissues among which it comes, itself also promptlydegenerating. Even with this low power several tubes,evidenced by the darker, shaded streaks at the upper andlower portions, can be seen in the midst of the gumma. Fig. 4123 is taken from the same gumma, photo-graphed with the quarter-inch objective, near its right
