Brass model on which the data of Figure 8 were obtained. The smaller cylinder inserts into the larger through a hole in the bottom of the latter. Two of the small holes in the outer cylinder communicate with each chamber in the walls of the inner cylinder ; thus holes in outer and inner cylinders are not aligned. FIGURE 5. Apparatus for testing apertures in pairs. Each aperture is radially symmetrical and was oriented normal to the stream; dye was introduced through the small pipe, which also served as a support. Large collars on either end of the main tube reduced the sensitivity of flow through the tube to minor misalignments in the stream. form from the Cape Cod Canal. All were maintained in running sea water and used within a clay of collection. In the erect form, active pumping usually ceased within a few hours after the sponges were received, probably due to the warmer water at the laboratory. With the addition of curved corner fairings, a sea-table, 132 X 7(> X 10 cm inside, provided an adequate flow tank for tise with the fresh sponges. The supply hose, fixed to one wall and directed downstream, propelled water at up to 10 cm/ sec. Water left through a porous cylinder fixed to the drain, thereby providing a continuously changing medium in the tank and facilitating observations of the pat- terns of flow with dye markers. Of several colored materials used, a concentrated.
