rarely, nodules may form in the cihary body or near the canal of 

 Fontana, giving rise to an irido-cyclitis or irido-choroiditis. 



Lie has studied the pathology of these lesions, and has shown 

 that it is rare for the optic nerve, the retina, the lens, and the 

 vitreous humour to be affected. 



The mucosae of the nose may be attacked, with, first, blocking of 

 the passage, and then, when the leproma extends down to the
