The opening of Preface
This volume is the continuation of ‘A History of Epidemics in Britain from A.D. 664 to the Extinction of Plague’ (which was published three years ago), and is the completion of the history to the present time. The two volumes may be referred to conveniently as the first and second of a ‘History of Epidemics in Britain.’ In adhering to the plan of a systematic history instead of annals I have encountered more difficulties in the second volume than in the first. In the earlier period the predominant infection was Plague, which was not only of so uniform a type as to give no trouble, in the nosological sense, but was often so dramatic in its occasions and so enormous in its effects as to make a fitting historical theme.
