 namely, vaccinia virus. It is hiojily jjrobable that these phenomena 

 determine the pathogenesis ol ( ertain complications in the course 

 ol infections. 



But I shall say no more, tor it is not litting ior me to penetrate 

 into the intimacy of the prol)lem. In fact, Dr. Shwartzman treats 

 it in a most complete fashion. In an impressive documentation he 

 exposes his own experiments and those which nimierous other in- 

 vestigators, attracted by the novelty and interest of the subject, 

 have eagerly tnidertaken. In spite of the efforts spent, tlie problem 

 has not yet been completely elucidated since the genesis of the 

 symptoms observed is still some^vhat of a mystery. A debt of grati- 

 tude is due to Dr. Shwartzman for having discovered the phenom- 

 enon descril)ed in this book; a debt of gratitude is also due him 

 for having proceeded Avith his researches on this imjDortant prob- 

 lem with the great precision ^vhich he alone could achieve.
