An attempt is made in this thesis, to discuss
the disease of variola or smallpox as a whole,
laying more particular stress, however, on those
points which have a hearing on the diagnosis, and
at the same time to present a summary of more recent
research on the subject with a view to explaining
the etiology and clinical features of the disease.
The subject is considered in the light of
experience gained during the three and a half years
I was attached to the Metropolitan Asylums Board's
Smallpox Service when I had an opportunity of seeing
most of the cases certified as smallpox.
