REJECTION OF JENNER’S PRESCRIPTION.
I have said that the world gave a cordial and unhesitating welcome to Jenner’s revelation, but the observation requires a startling qualification. Jenner’s revelation as conveyed in his Inquiry was summarily and ignominiously rejected—was absolutely rejected. I wish to emphasise this point. Jenner published his Inquiry in order to recommend horsegrease cowpox, and what I have to say is, that the public declined to have anything to do with horsegrease cowpox. The origin of cowpox in horsegrease was scouted as an intolerable origin. It was disgusting. Why a diseased secretion from horses’ heels should be more repulsive than a similar secretion from cows’ teats was not explained; but, as we all know, there is no accounting for tastes. Various attempts were made to verify Jenner’s prescription by inoculating cows with horsegrease, but they ended in failure—fortunately, it was said, in failure; for as Dr. Pearson (chief among primitive vaccinators) observed, “The very name of horsegrease was like to have damned the whole thing.” What did Jenner do under these circumstances? Did he confront the public and assert the efficacy of horsegrease cowpox? Not he. He wanted money. He saw how the wind was blowing. He said not another word about horsegrease cowpox; and as the public were eager at any price to escape from the nuisance of smallpox inoculation, and disposed to substitute cowpox as a harmless substitute, why then he resolved to go in for cowpox, and pose as its discoverer and promoter.
