When he had escaped the lazaretto and returned to England, he wrote a letter to the gentlemen who had undertaken to collect subscriptions, requesting them to lay aside their project. The money collected was in part returned, a part was spent in liberating a certain number of poor debtors, and the residue was applied towards erecting, at his death, the statue of him in St Paul's Cathedral. His son he was compelled to consign to the care of a lunatic asylum. He now published the information he had obtained, at so much risk, upon lazarettos, and the mode of performing quarantine, together with additional observations upon prisons and hospitals at home and abroad. Connected with this publication, an incident is related, which shows the extraordinary value Howard had put on the materials he had collected, and also the singular perseverance and determination of the man. We give it in the words of Mr Brown:-- "On his return from his Turkish tour, one of his boxes was stolen as he was getting into a hackney-coach in Bishopsgate Street, from the stage in which he had travelled from Dover. It contained a duplicate of his travels, twenty-five guineas, and a gold watch. The plan of the lazaretto of Marseilles, of which he possessed no duplicate, was, happily, _in the other box_. Had it not been so, he declared to his friend Dr Lettsom, that, notwithstanding the risks he had run in procuring that document, so important did he consider it, that he would a second time have exposed himself to the danger of a visit to France to supply its place." We believe he would. This publication completed, and his son so unhappily disposed of, the veteran philanthropist quitted his country again, and for the last time. It was still against the plague that his enterprise was directed. He seems to have thought that successful barricades, by quarantine and other measures, might be erected against it. With the plague, as with the cholera, it is generally admitted there is some occult cause which science has not yet penetrated; but the predisposing, or rather the co-operating causes, are, in both cases, dirt and bad diet; and the quarantine which would attack _these_ is the only measure which, in our present state of knowledge, is worthy of serious consideration. It was his purpose, this time, to travel through Russia into Turkey, and thence, perhaps, to extend his journey far into the East, to whatever city this grim enemy of mankind might have taken possession of.
