existence, assailable by smallpox.” In a letter to his friend Moore in 1810, Jenner said, “Cases of smallpox after inoculation are innumerable.” And again, “Thousands might be collected; for every parish in the kingdom can give its case.” And he asked another correspondent, Dunning, in 1805, “Is it possible that any one can be so absurd as to argue on the impossibility of smallpox after vaccination!” And this from Jenner, who had deceived the nation in 1802 with the assurance that, “inoculated cowpox was attended with the singularly beneficial effect of rendering through life the person so inoculated perfectly secure from the infection of smallpox”! Such was Jenner; such his inconsistency; and such the admissions he was driven to make under stress of failures many and manifest. SMALLPOX MADE MILDER. As vaccination failed to afford the protection originally guaranteed, various explanations were devised to enable those who had talked too loftily to eat humble pie without painful observation. One of the commonest excuses was that if vaccination did not prevent smallpox it made it milder: and inasmuch as no one knew, or could know, how severe any attack of smallpox would have been _without_ vaccination, it was an assertion as indisputable as the reverse--namely, that vaccination not only made smallpox severer, but frequently induced the disease. There are many assertions with which there is no reckoning, for it would require omniscience to check them. Let us beware of such assertions. Let us neither make them, nor suffer ourselves to be imposed upon by them. PUNCTURES, ONE OR SEVERAL. Another excuse was advanced in the report of the National Vaccine Establishment in 1814. It was said the failures in vaccination appeared to result from the practice Of making only one puncture for the insertion of virus. One puncture ineffective! Why, if one puncture were ineffective, how were the early miracles of vaccination to be accounted for, all of which had been effected by means of single punctures? MR. RIGBY’S PROTEST.
