Socrates. One, two, three ; but where, my dear Timaeus, is the fourth of those who were yesterday my guests and are to be my entertainers to-day ?
Timaeus. He has been taken ill, Socrates ; for he would not willingly have been absent from this gathering.
Soc. Then, if he is not coming, you and the two others must supply his place.
Tim. Certainly, and we will do all that we can ; having been handsomely entertained by you yesterday, those of us who remain should be only too glad to return your hospitality.
