Because the _Poetical Essay on the Existing State of Things_ was advertised in the _Times_ of the 10th April, and 11th April, 1811, and because Hogg says never a word about that perplexing publication (that in all probability was never published), Mr. Denis Florence MacCarthy maintains that the poem was on sale during that month in London, and that (without letting Hogg know aught of the matter), Shelley made daily runs from Poland Street to Messrs. B. Crosby and Co.'s shop, to inquire how much the sale of the poem was doing for Mr. Finerty's advantage. It may be taken for certain that if Shelley made daily calls on the booksellers, Hogg knew why his friend called on them. It may also be assumed that, instead of appearing in the _Times_ because the poem was then on sale, the advertisements appeared in the morning journals because their insertion had been ordered (with the usual prepayment) from Oxford some three weeks earlier, when there was, perhaps, an intention to publish the poem, that probably never was published. But if he never crossed the bookseller's threshold, Shelley was seen more than once at Mr. Abernethy's anatomical lectures, and oftener in the dissecting-room of St. Bartholomew's Hospital, where Charles Henry Grove (nearly two years Shelley's junior) was at that time a medical student. Hogg would have us believe that to his people in Durham Co. and Yorkshire, Mr. Timothy Shelley (known to them by his not uniformly perspicuous epistles) appeared a 'bore of the first magnitude, and a serious impediment to carrying into effect any ordinary arrangement.' Facts, however, make it certain that Mr. Hogg, the Elder of Norton, agreed with this bore of the first magnitude in thinking their boys must be parted, and kept from one another, at least for a considerable period. The letter, in which Mr. Shelley spoke his mind to his afflicted fellow-sufferer, through the afflicted fellow-sufferer's London agent, was dated 14th of April, 1811. Four days later (18th April, 1811), Mr. Thomas Jefferson Hogg was on the roof of a stage-coach, journeying from London towards North Wales, where he was allowed to visit a few friends, before going into pupilage under the conveyancer at York. The dates are eloquent. The joint rebellion against parental authority, which put Shelley in conflict with the Squire of Field Place, was fruitful of a paternal command to Mr. Thomas Jefferson Hogg, that he should pack his traps and move out of London without delay. Mr. Thomas Jefferson Hogg did as he was bid, and for nearly twenty weeks the young men were separated. Thus rudely severed by domestic tyranny, they cheered one another through the post.
