From my earliest years I felt a love for the investigation of natural things. It is often regarded as an instinct of cruelty that children like at last to break, tear, and devour objects with which for a long time they have played, and which they have handled in various manners.

I remember, that, when a child, I pulled flowers to pieces to see how the leaves were inserted into the calyx, or even plucked birds to observe how the feathers were inserted into the wings. Children are not to be blamed for this, when even our naturalists believe they get their knowledge oftener by separation and division than by union and combination, . . .
