But if these be indeed plain and legitimate conclusions from the facts and arguments which have been adduced—and to myself they appear irresistible ones—then must Vaccination cease to be considered as a matter of policy, or of curious medical research only, for it plainly resolves itself into a momentous moral question. Let it once be admitted that it is capable of eradicating so great an evil as the infection of Small Pox, and it becomes the imperative duty of every individual to promote, to the utmost of his ability, an end so infinitely desirable. The question involves consequences so closely connected with the well-being of individuals and of society in general, and the actual existence of so many thousands annually, that ignorance, or doubt, will scarcely form an admissible apology for the omission of what is alike essential for private and for public security. If then any be ignorant on this momentous subject, let him not delay to obtain information; if any doubt, let him use every exertion to satisfy himself. If he hesitate to confer on his children the advantages, which Vaccination has been proved to be capable of bestowing, let him remember, that it has already been the means of preserving nearly four hundred thousand of his countrymen, and that, perhaps, he owes his own existence at this day, to its salutary influence; that but for Vaccination he might possibly himself, long ago, have fallen a sacrifice to the destructive disease from which it has rescued so many victims, and have been equally unable to call its efficacy in question, or to assist in consummating the grand object, which by means of it alone, appears capable of being accomplished. It was in our own country, that this most remarkable discovery originated; it was our own countryman, who, with such noble disinterestedness, as soon as he had satisfied himself of its real value, disclosed it to the world, and who sacrificed every personal consideration of pecuniary gain, to the general welfare of mankind. As Englishmen, we have just cause to be proud of both—the discovery and the discoverer; but we may well feel humbled when we remember, that the merits of neither have been adequately acknowledged amongst us; and that while the latter has been more justly estimated and more highly honoured in almost every other part of the world, the former has also been more effectively employed, and with proportionally more decisive results.
