NEW RESEARCHES UPON PLEURO PNEUMONIA AND 
ITS PREVENTIVE INOCULATION. 
By Dr. Willems. 
SECOND PART. 
After giving the concise history of the progress of inoculation * 
in the different countries of the globe; after having explored the 
extensive domain of positive and convincing facts in favor of that 
practice, facts observed and collected under most variable circum¬ 
stances, by savants and agriculturists, placed in the most opposite 
conditions, and even sometimes adverse to that practice ; after 
having given a short apercu of the deductions reached by the 
most authorized observers, I continue this study on exudative 
pleuro-pneumonia by proposing some scientific and practical con¬ 
siderations, which I submit with confidence to the high appreciation 
of the Academy. 
* This forms the first part of the paper, and consist in a review of the results 
obtained from the operation in different parts of the world.
