They look at first as if sprinkled writh fine dust, owing to the accumu-lation in their interior of a fatty substance in extremely minute drops. At the sametime that the lens fibers get cloudy, their caliber becomes uneven, because they swellup in spots (q, Fig. 225). In this way bodies that are large, vesicular, and frequentlynucleated (vesicular cells; b, Fig. 225) are produced. Finally, the lens fibers breakdown completely, so that from the lens tissue is formed a pultaceous mass consistingof drops of fat, the so-called spheres of Morgagni (a coagulation product, Fig. 225, M) l; ^ h
