Question

Often, of an evening, when he sat at the window, his desk and papers before him, he would cease reading or writing, rest his chin on his hand, and deliver himself up to I know not what course of thought; but that it was perturbed and exciting might be seen in the frequent flash and changeful dilation of his eye.

Accepted Answer

A veces, por las tardes, al sentarse junto a la ventana, con sus papeles ante sí, dejaba de escribir o de leer y se entregaba a no sé qué clase de pensamientos, que evidentemente, le excitaban y le perturbaban, como se podía apreciar por la expresión de sus ojos.
