 in Thoreau’s Journal:

I think Ruskin is wrong about reflections in his “Elements of Drawing,” page 181.  He says the reflection is merely the substance “reversed” or “topsy-turvey,” and adds, “Whatever you can see from the place in which you stand of the solid objects so reversed under the water, you will see in the reflection, always in the true perspective of the solid objects so reversed.”
