Ringers solution at a temperature of 37°C. entered thelimb by way of the iliac artery under pressure of 100 mm. of same amount of adrenalin as before was injected into the generalcirculation. The first time the perfused limb dilated cc. while atthe second injection the expansion was cc. In other words theamount of dilatation was about the same when circulatory connectionwas destroyed as when it was intact (see figs. 7 and 8). The amount of dilatation varied with the dose; cc, 1:10,000gave cc, while 1 cc, 1:10,000 gave cc. After the limb hadbeen perfused one and one-half hours, cc adrenalin, 1:10,000 intothe jugular vein gave only cc. dilatation. Another interesting 362 t-RANK A. HARTMAN AND LOIS MCP. FRASER. Fig. 6.
