1. It is really beautiful how quickly and well
Drosera and Dionaea dissolve little cubes
of albumen and gelatine.
I kept the same sized cubes on wet moss
for comparison. When you were here
I forgot that I had tried gelatine,
but albumen is far better for watching
its dissolution and absorption. Frankland
has told me how to test in a rough way
for pepsin;
and in the autumn
he will discover
what acid the digestive juice contains.
