the East, and to try to overwhelm his adversaries with evidence which they could not overtake; but any one of judicial temper must have perceived that if vaccination was to be vindicated, data of a very different order would have to be forthcoming. Where the number of the population in a distant region was unknown, where the ordinary prevalence of smallpox among the people was undefined, where the extent of artificial variolation was unspecified, and the existence and intensity of related forms of zymotic disease were undescribed, what conclusion could be drawn as to the efficacy of vaccination that a man of science was bound to respect? Why should certain knowledge in England be surrendered for assertion from abroad. CHAPTER XXX. DIFFUSION OF VACCINATION THROUGHOUT EUROPE. VACCINATION was accepted as a revelation, and diffused as a religion, and was almost everywhere received gladly. We have to bear in mind, however, that the way had been made straight for it by the practice of inoculation with smallpox; which practice, after a struggle prolonged over many years, had become an established part of medical art, and was only limited in its application by the inconvenience and risks that attended it. The promise of the primitive vaccinators was, that the security which resulted from inoculation with smallpox was to be had from inoculation with cowpox, with absolute certainty, absolute safety, and absolute permanence. The argument was, that since no one could have smallpox twice (however slight the attack), and as cowpox was a mild form of smallpox, it sufficed to be inoculated with cowpox to be safe from smallpox through life; and if only the infliction of cowpox were made universal, smallpox would be extirpated. Such was the plausible doctrine; so plausible that it had only to be stated to command assent; whilst so great was the elation over the discovery (as much, perhaps, for deliverance from inoculation with smallpox as from smallpox itself) that it was accounted a sacred duty to diffuse its benefits over the whole earth. Greater good on easier terms it was difficult to imagine. With a scratch of a needle one of the worst penalties attached to over-crowding, to filth, and to ill-living, might be avoided and done away with for ever. How pleasant are such sugared lies, The first cowpox missionaries were Dr. Marshall and Dr. Walker. £100 was teased out of the Admiralty, and £100 out of the War Office toward their expenses, and placed on board the Endymion, they proceeded, on 1st July, 1800, to the Mediterranean. At Gibraltar, Minorca, and Malta, they vaccinated soldiers and sailors, first operating on orphans and foundlings to give the gallant fellows courage. Then Walker accompanied Sir Ralph Abercrombie to Egypt, from whence, after a variety of adventures, he returned to London to serve as domestic apostle, and vex Jenner for the remainder of his life. Marshall proceeded to Sicily and Naples. In Palermo, in the preceding year, 1799, there had been an epidemic. in which, it was said, 8,000 had perished, and Marshall appeared on the scene as a belated messenger of salvation. At Naples he had a cordial reception from the wretched Ferdinand IV. and his wretched court, who, with general indifference or enmity to what was good, were ready to show themselves gracious toward cowpox. Marshall went through the customary performances of the variolous test and the exposure of the vaccinated to infection; and without further ado an hospital was opened, and all who would be saved from smallpox were entreated to hasten and receive the new inoculation. It was not unusual [wrote Marshall to Jenner] to see in the morning a procession of men, women, and children, conducted through the streets by a priest carrying a cross, coming to the hospital to be inoculated. By such popular means, the practice met with no opposition; and the common people expressed themselves as certain that it was a blessing sent from Heaven, though discovered by one heretic and practised by another. When Marshall was at Gibraltar, Lord Keith issued the following memorandum to the fleet H.M. Ship Foudroyant, GIBRALTAR BAY, 19th October, 1800. Any soldiers, seamen, or marines in the Fleet who may not have had the Smallpox, and wish to avoid that dreadful malady, may, by application to Dr. Marshall, on board the flag-ship, be inoculated with the Cowpox, which, without pain or illness, or requiring particular diet or state of body, or leaving any marks, effectually excludes all possibility of the patient ever being affected with the Smallpox. By command of the Vice-Admiral, To the respective Captains of the Fleet. PHILIP BEAVER. I may observe, in passing, that there was little delay in introducing vaccination to the British navy. Sir Gilbert Blane was urgent, Earl Spencer, first Lord of the Admiralty, acquiescent, and Dr. Trotter, physician to the fleet, enthusiastic. So early as 9th December, 1800, Trotter was prophesying The Jennerian Inoculation will be deservedly recorded as one of the greatest blessings to the navy of Great Britain that ever was extended to it. Smallpox was one of the pests of the service. Trotter, writing 20th February, 1801, said— Within the past seven years there have been more than a hundred instances in which the seamen have been infected; twenty having occurred in the last six months in the Channel fleet alone. These outbreaks were invariably referred to an origin external to the ship; as if anywhere smallpox could have had a more congenial breeding-place than the crew of a man-of-war! As Dr. Johnson observed, "When you look down from the quarter-deck to the space below, you see the utmost extremity of human misery; such crowding, such filth, such stench!"* Incited by the enthusi * Boswell (Croker's Ed.) vol. vii. p. 102. astic Trotter, the medical officers of the Fleet subscribed for a gold medal, and presented it to Jenner. On the obverse, Apollo was represented introducing a young seaman recovered from cowpox to Britannia, who, in return, extended a civic crown, on which was inscribed JENNER; above were the words, Alba nautis stella refulsit, and below the date, 1801. On the reverse was an anchor and over it Georgio Tertio Rege, and under it Spencer Duces. The medal was presented to Jenner in February. 1801. The dates are worth noting afresh. Jenner's Inquiry was published in the summer of 1798; and thus we see that within three years his prescription for the prevention and extermination of smallpox was adopted in a branch of the public service where obstinate conservatism was the ruling temper; and an assertion that only time. could test was accepted without hesitation as verified and certain. If vaccination had answered to the claim made for it, the haste wherewith it was acknowledged would have been unjustifiable, and wholly unlike the struggle that truth has commonly to pass through in order to obtain supremacy in the intellect and practice of mankind. The first attempts to inoculate with cowpox in France proving futile, Dr. Woodville went over to Paris in 1800 to show in practice the method of operation. He had a warm reception, and the Quaker was overwhelmed with the exuberant attentions to which he was subjected. In the Moniteur he was described as "a learned man, animated with generous zeal, and worthy of gratitude and praise;" who had inoculated six thousand children with invariable success; and that cowpox as a preventive of smallpox could only be spoken of as something miraculous. A house was opened as a vaccine station, and men, women, and children, flocked thither to receive the benign fluid and life-long protection from a dreadful malady. When the negotiations for the peace of Amiens were in progress, 1802, an address was presented with much. pomp to the Marquis Cornwallis by the Medical Com mittee of the Somme, claiming brotherhood with the physicians of England, eulogising Jenner, denouncing his detractors, stigmatising variolators as acting neither from the love of truth nor for the glory of their profession, but, from avarice and hatred of improvement; whilst, as the result of numerous experiments, "the discovery made in England had been stamped with the seal of infallibility in France." At first, vaccination in France was left to voluntary effort, and made little progress in face of a strenuous resistance developed by alarmed variolators; but a severe smallpox epidemic in 1802 incited the Government to action. A medical commission was appointed to investigate and report, and in 1804 it was determined to spare no effort to extend vaccination over the whole of France. A Central Committee for Vaccination was constituted, and appeals and commands were addressed to the clergy and officials of all orders to have those under their authority and influence inoculated with cowpox. Some préfects were content to recommend and warn, but others adopted more vigorous measures, such as the exclusion of the unvaccinated from schools, from employment, from charities-in short, anticipating much legislation that has come into force, or that fanaties wish to bring into force. Nevertheless, the progress made did not satisfy Napoleon, and seeing that until vaccination was everywhere paid for by the State, its performance must remain irregular and perfunctory, a manifesto was issued to the effect that his Majesty the Emperor and King had learned from the reports of the Central Committee that the preservation and increase of his vast dominions were immediately related to systematic and universal vaccination; wherefore, his Majesty, wishing to give a signal mark of his paternal solicitude for his subjects, had granted to his Excellency the Minister of the Interior, an annual special credit, destined to provide for the expenses necessary for extending the new practice, and for forming centres of issue of vaccine virus in twenty-four of the chief cities of the Empire-these, then, including Brussels, Florence, Parma |
