Introduction to Bacteriology.* — Prof. F. Hueppe’s Introduction to 
Bacteriology is one of those professorial exercises which are wont to be 
put forth on the occasion of the jubilee of some distinguished person, or 
dedicated to the honour of some ancient foundation. As might have 
been expected from the position of the author, the present monograph 
deals with the numerous aspects of Bacteriology in a thorough and 
scientific manner. The tone is impartial and the matter up to date. 
Its most interesting features are the discussions on the nature and effects 
of the bacterial poisons and the methods for dealing with disease. After 
describing the chief features of the morphology of bacteria, the pheno- 
mena of their life-history are reviewed. These are followed by a short 
account of the more important pathogenic micro-organisms and of the 
causes of disease. Immunity, protective and curative inoculation are 
then discussed at some length. In this section protective serum and its 
action receive considerable attention. The work concludes with chapters 
on the prevention of disease and the history of Bacteriology.
