Life is nearly over with me. I have taken no pains about my style of writing.

I am dying by inches, from not having any body to talk to about insects.

I agree with Agassiz that dogs possess something very like conscience.

If I had life to live over again, I would give my life to poetry, to music, to literature, and to art to make life richer and happier. In my youth I steeled myself against them and thought them so much waste.

Much love much trial, but what an utter desert is life without love.

The most energetic workers I have encountered in my world travels are the vegetarian miners of Chile.

I can remember the very spot in the road, whilst in my carriage, when to my joy the solution occurred to me.
