Letters 83.3

To-day has been unbroken; no one has filched the slightest part of it from me. The whole time has been divided between rest and reading. A brief space has been given over to bodily exercise, and on this ground I can thank old age—my exercise costs very little effort; as soon as I stir, I am tired. And weariness is the aim and end of exercise, no matter how strong one is.
