Some observations on the crystalline lens

hour and finally a precipitate was formed
in it.

Lenses were immersed in water for one
day and the fluid was afterwards exposed
to these radiations. It became opalescent after
twenty minutes and a light precipitate was
formed later.

In both cases, the appearance
was due to precipitation of dissolved lens
proteins by the radiations.

Lenses without capsules were immersed for
20 hours in fluids of different H-ion concentrations
and the fluids were afterwards exposed to the
radiations from the mercury-vapour lamp for
an hour. Acid potassium phosphate solution of
pH 4.2 became opalescent in half an hour, and
the opalescence increased to the end of the
hour's exposure; a mixture of acid potassium
phosphate and sodium hydroxide solutions of pH 6.6
became very slightly opalescent, and a mixture
of the same solutions of pH 8.4 showed no change.
