The lovely lady, unaware that we were parties to her guilty secret, went with us, accompanied by her numerous attendants, and looking as beautiful, and hardly less innocent, than an angel. Long afterwards, Lord Westport and I met her, hanging upon the arm of her husband, a manly and good-natured man, of polished manners, to whom she introduced us; for she voluntarily challenged us as her fellow- voyagers, and, I suppose, had no suspicion which pointed in our direction. She even joined her husband in cordially pressing us to visit them at their magnificent _chateau_. Upon us, meantime, whatever might be _her_ levity, the secret of which accident had put us in possession pressed with a weight of awe; we shuddered at our own discovery; and we both agreed to drop no hint of it in any direction. [14] Landing about three miles from Dublin, (according to my present remembrance at Dunleary,) we were not long in reaching Sackville Street. FOOTNOTES [1] "_Ancient Rome_."--Vast, however, as the London is of this day, I incline to think that it is below the Rome of Trajan. It has long been a settled opinion amongst scholars, that the computations of Lipsius, on this point, were prodigiously overcharged; and formerly I shared in that belief. But closer study of the question, and a laborious _collation_ of the different data, (for any single record, independently considered, can here establish nothing,) have satisfied me that Lipsius was nearer the truth than his critics; and that the Roman population of every class-- slaves, aliens, peoples of the suburbs, included--lay between four and six millions; in which case the London of 1833, which counts more than a million and a half, but less than two millions, [_Note_.--Our present London of 1853 counts two millions, plus as many thousands as there are days in the year,] may be taken, _chata platos_ as lying between one fourth and one third of Rome. To discuss this question thoroughly would require a separate memoir, for which, after all, there are not sufficient materials: meantime I will make this remark: That the ordinary computations of a million, or a million and a quarter, derived from the surviving accounts of the different "regions," apply to Rome _within_ the Pomaerium, and are, therefore, no more valid for the total Rome of Trajan's time, stretching so many miles beyond it, than the bills of mortality for what is technically "London within the walls" can serve at this day as a base for estimating the population of that total London which we mean and presume in our daily conversation. _Secondly_, even for the Rome within these limits the computations are not commensurate, by not allowing for the prodigious _height_ of the houses in Rome, which much transcended that of modern cities. On this last point I will translate a remarkable sentence from the Greek rhetorician Aristides, [_Note_.--Aelius Aristides, Greek by his birth, who flourished in the
