PLATE VIII. 
Fig. 1.—Purkinje’s figures, or shadows of the retinal vessels seen 
entoptically. The appearance shown is that exhibited 
near the fovea, which latter probably gives rise to the 
granular appearance seen near the centre. 
Fig. 2.—Moving corpuscles near the retina, seen entoptically. They 
are probably due to the white corpuscles of the blood, and 
are seen as actively moving points of light, smaller than 
are actually depicted in the figure.
