Some observations on the crystalline lens

process. Some of these lenses were kept in the
dark, others were  kept in the daylight, and others
were exposed to the radiations from the
carbon-tungsten ore filtered through water in a uviol glass cell and concentrated by a quartz
lens. No differences were observed in the
short exposures tried.

Some of the lenses after immersion in
calcium chloride were transferred to distilled water. After an hour's immersion in distilled
water, the patchy opacity had cleared, but
there remained a little thread-like precipitate
immediately under the capsule. Weighings
showed that the lenses which had been in
the stronger calcium solutions did not take
up distilled water, while those from the weaker
solutions gained, but at a much slower rate
than lenses which had not been previously
heated with calcium.
