Against such a paragraph we may write, Sheer romance! Jenner was by no means reticent, and that the prevention of smallpox was for any length of time the burden of his soul, nowhere appears. The romance came into being after date in order to make much of little, and to justify payment in cash and reputation. For, taking Vaccination at the utmost, it was a slight advance upon existent knowledge and practice. In the first place, it was a notorious belief in many dairy districts, that to contract cowpox was equivalent to smallpox in averting a subsequent attack of smallpox. In the second place, inoculation with smallpox was the custom of the time; and if infection with cowpox prevented smallpox, why should not inoculation with cowpox do so as effectually as inoculation with smallpox? The intelligence requisite to reach a conclusion so obvious was not great, and therefore it was no cause for surprise that when Jenner’s claim as originator of Vaccination was brought forward, his priority should be disputed from several quarters; as by Benjamin Jesty of Yetminster, who inoculated his wife and sons with cowpox in 1774; by Nash of Shaftesbury; Mrs. Rendall, and others. Jenner was not insensible to the force of these claims, but evaded them under the plea that there was cowpox and cowpox, and that he had discovered and defined the right sort.
In parts of Holstein, too, cowpox was regarded as good against smallpox, and on more than one occasion was deliberately employed for the purpose. Plett, a village schoolmaster, near Kiel, inoculated three children with the disease in 1791, who were afterwards credited with resisting variolous infection in consequence of their vaccination.[86]
How thoroughly the asserted prophylaxy of cowpox was known, Jenner himself was accustomed to bear witness. He was a member of two clubs, the Medico-Convivial which met at Rodborough, and the Convivio-Medical which met at Alveston; and he used to bring cowpox so persistently under discussion, that, he said, he was threatened with expulsion if he did not desist. “We know,” said the jovial doctors, “that an attack of cowpox is reputed to prevent smallpox, but we know that it does not, and that should end the matter.”[87]
In pursuance of the tactics that would represent Vaccination as the outcome of the labour of many years, we have the following extraordinary narrative from Baron, Jenner’s biographer—
It was not till 1780 that Jenner was enabled, after much study and inquiry, to unravel many of the perplexing obscurities and contradictions with which the question of cowpox was enveloped, and which had impressed those who knew the traditions of the country with the opinion that it defied all accurate and satisfactory elucidation. In the month of May of the year just mentioned, 1780, he first disclosed his hopes and his fears, respecting the great object of his pursuit, to his friend Edward Gardner. By this time Jenner’s mind had caught a glimpse of the reputation which awaited him, but it was still clouded by doubts and difficulties. He then seemed to feel that it might, in God’s good providence, be his lot to stand between the living and the dead, and that through him a plague might be stayed. On the other side, the dread of disappointment, and the probability of failing to accomplish his purpose, restrained that eagerness which otherwise would have prompted him prematurely to publish the result of his inquiries, and thereby, probably, by conveying insufficient knowledge, blight forever his favourite hope.[88]
Many are the marvellous relations in ancient and modern history, but in the records of the supernatural it is questionable if there be anything to match the preceding. Painters depict the runaway apprentice listening on Highgate Hill to the bells as they pealed, “Turn again Whittington, twice Lord Mayor of London,” but they might find a finer subject in the young Gloucestershire surgeon, aged 31, habited “in blue coat and yellow buttons, buckskins, well polished jockey boots with handsome silver spurs, a smart whip with silver handle, and hair done up in a club under a broad-brimmed hat,”[89] with eye fixed in vision, contemplating his glorious destiny, through clouds of doubt and difficulty, full twenty years ahead; standing like another Aaron, censer in hand, between the living and the dead until the plague was stayed! Verily, if we do not see miracles, it is because we do not choose to look for them.
The chapter of the wonderful is not exhausted; yet greater things remain. Says Baron, and recollect the year was 1780 and Jenner aged 31—
Jenner was riding with Gardner, on the road between Gloucester and Bristol, near Newport, when the conversation passed of which I have made mention. He went over the natural history of cowpox; stated his opinion as to the origin of this affection from the heel of the horse; specified the different sorts of disease which attacked the milkers when they handled infected cows; dwelt upon the variety which afforded protection against smallpox; and with deep and anxious emotion mentioned his hope of being able to propagate that variety from one human being to another, till he had disseminated the practice all over the globe, to the total extinction of smallpox—
Which is to say, that in 1780, Jenner, aged 31, had arrived at the conclusion which he offered to the world in 1798 at the mature age of 49; and in the meanwhile allowed mankind to perish from smallpox, he having their salvation in his hands!
The miraculous conversation, says Baron, was concluded by Jenner in words to the following effect—
