Abstract
EXPERIMENTS on the significance of the aqueous humour in the lens's metabolism, which I have been carrying out during the past few years1, have shown that the power of the aqueous humour of cattle and of the rabbit to reduce methylene blue does not depend upon the presence of an enzyme, but essentially upon a reducing substance which is present in the trichloracetic acid filtrate and can be titrated with iodine. The trichloracetic acid filtrate, as well as the aqueous humour in which the protein has been deactivated by heating, obtained from 1 c.c. of aqueous humour, unites with approximately 1 c.c. of a N/500 iodine solution.
