O ur friend Castricius handed me your letter yesterday as I was leaving the baths, and I asked him to come to me for an answer in the morning. During the night I suffered so much from cough and sleeplessness that I was obliged to stay in bed till 11 o'clock. That accounts for my keeping our friend Castricius back. You shall have the books of Cicero corrected and punctuated. Those which I have annotated please keep for your own eye. I will write to you more carefully the reasons why I do not wish them to become public property.
