Having found liberty in the truth, he reverted to Jenner’s writings, and reading them with opened eyes, he was not slow to detect and to demonstrate the laxity of statement, the contradictions, and absurdities with which they were pervaded. No reply was attempted: no reply, indeed, was possible. The surgeons of the Edinburgh Vaccine Institution issued An Examination of Mr. Brown’s Opinions and Statements,[167] but they merely carped over non-essential details, and left the main issues wholly unaffected. What they had to show was that Brown’s patients were either unvaccinated, or had not had smallpox; and unable to do this, they were unable to do anything.
Brown remained victor. He did not overthrow vaccination, nor restore variolation, but he did make an end in Scotland of confidence in vaccination as an omnipotent safeguard against smallpox. The rite continued to be practised on humbler terms: “it did no harm”: even Mr. Brown allowed that it might keep off smallpox for a time: and “there was reason to believe that it tended to make the disease milder when it did occur.” Thirty years after his first publication, in 1842, Brown reaffirmed his position in a series of letters[168] to Dr. George Gregory, a sympathetic friend, and advised a return to variolation in view of “the acknowledged defects of the Jennerian practice”—a dismal alternative. But it is in vain to expect any man to be much in advance of his time: it suffices for honourable distinction that he be in advance. When Brown commenced practice, smallpox and other fevers were regarded as inevitable as storms and earthquakes, and the knowledge with which we are now so familiar, that they are engendered in foul habits and habitations, was for practical purposes unknown. Our reproach is, that knowing so much better, we surrender ourselves to a superstitious observance conceived in days of darkness.
