From the prisoner, and the subject of prison-discipline, it is well known that the attention of Howard was directed to measures for arresting the plague. It was a grand idea this--that he would lead the way to some general scheme to be adopted throughout Europe, and the contiguous parts of Asia, for checking the incursions of, and perhaps finally exterminating, the plague. For no object did he suffer so much, or expose himself to so great dangers; embarking purposely in a vessel with a foul bill of health, and undergoing the perilous confinement of the lazaretto, that every practice of the quarantine might be thoroughly known to him. Nowhere was his conduct more heroic. It cannot be said here, however, that his object was equally well chosen, or that his labours were attended with any good result. Whilst it would be difficult to over-estimate the value of his service as inspector-general of the prisons of Europe, we can detect nothing in this latter scheme but an unfortunate waste of heroic benevolence. In dealing with jails and houses of correction, he was dealing with evils, the nature of which he, and all men, could well understand; but, in dealing with the pestilence, he was utterly in the dark as to the very nature of the calamity he was encountering. It is very probable that, had he realised his utmost wishes, and built a lazaretto on the most improved plan, combining every valuable regulation he had observed in every lazaretto of Europe, it would only have proved an additional nuisance. This period of his life is more full of striking incidents than any other, but we must hurry rapidly over it.
