This is the canalis hjaloideus or ccmal of StiUing. It is bestshown in the fresh eye, and may be also injected by forcing a colouredsolution under the pia-matral sheath of the optic nerve (Schwalbe).The canal widens somewhat towards its posterior part : its wall iscomposed of an extremely delicate homogeneous membrane. It repre-sents the place of passage of an offset from the central artery of theretina to the capsule of the lens in the Fig. 359.—Transverse section op human eye, hardenedIN chromic acid, showing kadial striation of theVITREOUS BODY (after Hannover).
