PLATE IV. 
Pupillary disc and obscurities in crystalline lens of the author's 
left (L.) and right (R.) eyes, as seen and delineated by the 
author with the Entoptiscope, showing growth of cataract 
in both eyes. The pupil and obscurities are magnified 
7 diameters. 
Drawing of the obscurities in the author’s eyes as seen by 
Dr. C. Fitzgerald, of Dublin, by means of the ophthalmo- 
scope, about the same date as the drawing in fig. 1. 
The same inverted both laterally and vertically to compare with 
fig. 1. 
Detailed drawing of the obscurities in the author’s right eye, as 
seen by Dr. Kttles, of London, by means of the ophthalmo- 
scope, for comparison with R., fig. 3. 
Entoptic view of his right crystalline lens made by Donders, 
the eye under a mydriatic. The normal stellate structure 
of the lens is here shown; most persons see in the 
Entoptiscope the bright star, sometimes with branching 
lines, indicating the structure of their crystalline.
