SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 767 
hygienists and veterinarians. From the journal which 
gives the above information ( Annates de Medecine Veteri - 
naive) we continue Dr. Willem’s paper on “ Pleuro¬ 
pneumonia Exsudativa,” as he terms the “ lung disease/’ “ I 
summarise my opinions on this subject in the following 
propositions. 
1. Pleuro-pneumonia exsudativa is a general and specific 
disease. 
2. It is contagious and inoculable by miasma (volatile 
virus) or by fixed virus. It never arises spontaneously. 
3. Inoculation produces a general disorder in every respect 
similar to that known as pleuro-pneumonia exsudativa. 
4. Pleuro-pneumonia exsudativa, except in very rare in¬ 
stances, affects an animal only once. 
5. The inoculated patient is unable to take pleuro¬ 
pneumonia ; he resists the contagion. 
6. Inoculation of an animal cured of pleuro-pneumonia 
gives no result; the same may be said of an animal previously 
successfully inoculated. 
7. Pleuro-pneumonia is a special disease, and affects only 
bovine animals ; it is transmissible to no other animal, not 
also to man, by direct inoculation. 
8. The pathological product of inoculation is in every 
respect like the matter exuded in the lungs and other 
organs of an affected animal. 
9. The inoculated animal transmits the disease only by 
inoculation. 
10. The fresh liquid produced by exudation in the lungs 
of a diseased animal, of the first or second remove, is the 
best material for inoculation. 
11. The tail of the animal is the best point for insertion 
of the virus. 
12. Inoculation produces more severe effects on animals 
and herds affected by the epizooty than on non-contaminated 
subjects or herds. 
13. Inoculation does not act by derivation, as do setons, 
&c.; it is not a simple septic inoculation. 
14. The virus of pleuro-pneumonia has the properties of 
a true contagium, being communicable from one animal to 
another, and having a stage of incubation, and multi¬ 
plying. 
*15. In the pulmonary exudate, in the pleural extravasa¬ 
tions, and in other parts of the sick animal, as also in the 
products of inoculation, may be found germ-corpuscles, 
microbia which are the agents of transmission of the disease. 
16. Pleuro-pneumonia, being now better understood,
