Biorocy, chemistry, medicine and surgery, in the progress of their 
evolution, have contributed little by little to the growth of a new 
branch of learning whose subsequent development has been of ines- 
timable importance toeach. Indeed, bacteriology illustrates the old 
adage, ‘The child is father of the man,’’ for while it is the offspring

_ In presenting this subject to our readers, we open with 
a brief history of bacteriology, as outlined by Joseph 
McFarland in his admirable work on Pathogenic Bacte- 
ria, published by W. B. Saunders of Philadelphia. 
Our aim is not only to-interest physicians, but also. to 
stimulate microscopists togreater effort and research along 
these lines. Bacteriology is not only a highly important
