The history of the Glasgow epidemic abundantly showed that the practice of vaccination by giving an immunity against small-pox for a given number of years had caused, when small-pox made its appearance in the city, the development of a large number of mild ambulant cases of the disease which were not discovered and which did not call for medical attendance.
