One of tlie first objects observed was the scales of the comroon 
Lepisma saccharina (the active "window fish" of onr childhood). 
The late Eichard Beck announced that the markings on the lower 
surface of this scale consisted entirely of fan-like radiations starting 
from the quill— a structure by some considered illusory ; but with 
axial vision thus refracted obliquely, the accuracy of this careful 
observer was confirmed, as these radiating lines were shown very 
distinctly, as if graven in black and white.
