exposure continued, and a precipitate forming
in about two hours.

A quantity of the lens albumen solution
was mixed with an equal quantity of a dilute solution of sodium silicate and exposed
to the radiations from the mercury-vapour
lamp, the temperature being kept below  20°C.
After 3 hours' exposure the solution was still
clear. A control solution diluted to the
same extent with water became opalescent in
less than an hour. The reaction of the
first solution was alkaline.

A lens albumen solution to which [text?]
sodium hydroxide solution had been added
became opalescent after half an hour's
exposure to the radiations and contained
a heavy precipitate at the end of two hours.

A solution of lens albumen was
exposed to the radiations with a solution
of sodium silicate 1 cm. in depth in a quartz
