By using a novel technique we have been able to follow the clearance and distribution of fluorescent latex particles injected into both the midventral sinus and pericardial sinus of the freshwater cray-fish,Orconecte virilis. The fluorescene of various tissues was determined over post-injection periods ranging from 1 h to 20 days. Particles were rapidly removed from the hemolymph (Figs. 1 and 2) and accumulated in the heart (Fig. 3), antennal glands (Fig. 4), gills (Fig. 5) and, to a lesser extent, hepatopancreas (Fig. 6). Other tissues contained fluorescence in concentrations proportional to their supply of hemolymph.
