race has to fight against the diseases of the world. Pasteur- 
ians endeavor to take care of all infectious diseases and help 
the man and his domestic animals to live. And to do this a 
regular living material must be used in order to carry out 
what the master has given—the principle of Louis Pasteur. 
In 1889 Paul Gibier arrived in New York with Dr. A. 
Leteve, ex-aide d’anatomie et ex-interne des Hopitaux de la 
Faculte de Medicine de Lille, France, as director of labora- 
tories, and started the Pasteur Institute of New York. Ten 
years later Dr. A. Leteve came to Pittsburgh, and started, 
with the help of the Sisters of Mercy, the Pasteur Institute at 
the Magee Pathological Institute of the Mercy Hospital. 
At this time the virus vaccine was received from Dr. Cal- 
mette, then director of the Pasteur Institute at Lille, France. 
The Pasteur Institute being necessarily an independent 
institution, a separation from the Mercy Hospital was made 
in 1919. Since 1924 the office of the Pasteur Institute of 
Pittsburgh, Pa., has been located in the Descalzi Building at 
1004 Wylie Avenue, with Dr. A. Leteve, consular agent of 
France and also the Director of the Pasteur Institute of 
Pittsburgh, in charge, and Walter B. Willis. director of 
laboratories. 
The record of this Institute in Pittsburgh and its treat- 
ment of rabies is widely known, having a percentage that is 
really enviable and astonishing in comparison with others 
who treat these cases, in fact, a mortality of 14 of 19. 
These few words are given in case of a supposed infection 
of rabies: 
(1) A person or persons bitten by a dog, no matter how 
small the wound, should keep the animal under observation 
{or 14 days, because the salvia of the animal is infectious six 
days, at least, before it shows any sign. 
(2) After two weeks if the dog or animal shows no sign 
the person is safe, but it is to be recommended that the wound 
be considered infectious and treated as such by a regular 
ohysican. 
Records of the Pasteur Institute have been preserved by 
the Mercy Hospital, and a treatise of the subject is given by 
Leasure K. Darbaker, Ph.G., Phar. D., head of the Depart- 
ment of Pharmacognosy and Bacteriology of the Pittsburgh
