The lenses in acid became hazy after one
hour's immersion and developed superficial
patchy opacity during the first day.

A pair of lenses without capsules heated in
the same manner showed similar but less
marked differences in weighings.

Lenses in their capsules were immersed in
Ringer and in isotonic acid solutions (acid
potassium phosphate) containing a drop of neutral
red. A pair of dog's lenses so treated were
cut in half after twenty-four hours; the lens
in Ringer's solution was found to be stained
an orange-red colour, while that in acid
was rose-pink. Lenses immersed for a
shorter period (half to one hour) showed only
very slight tinting, so that it was difficult
to judge of colours, but those immersed in
Ringer were orange in colour, while in the case
of those in acid solution, the capsule was rose-
pink and the cortex of the lens had a very
