The same immunity, more or less COM
plese and more or less durable, which the
majority Of persons in the midst Of an in
fecied district, enjoy an immunity which
attests the individual resistance to the toxic
principle, IS a Circumstance to which we
should attach the highest Importance.
In point Of view OF epidemic development,
it is the corrective Of transmissibility, and
viewed with regard to prophylaxia. II sets
in operation the proper means to arrest the
ravages Of the disease.

DEDUCTIONS RELATIVE TO THE GENERATIyF
PRINCIPLE OF CHOLERA.
| XVIII. From the facts above estab-
lished, and which relates to the genesis, the
propagation and the transmissibility Of
cholera, can we draw any precise conclusion
| with regard to the generative principle Of
the disease, or at least with regard TO the
media which serve as its vehicles, or recepta-
cles; with regard to the conditions of its
penetration into the organism, the ways by
which il passes out the duration Of its NOR
bific activity, in a word, with regard to all its
attributes, a knowledge of which is impor-
tant 10 guard against il
In the actual state of science, we can only
frame hypothesis as to the generative prin-
cipie of cholera; we know only that it origi-
mates in certain countries Of India, and that
it dwells there permanently; thatthis princi-
pie is reproduced in man and accompanies
him in his journeyings; that it it may alss
be 3ropagated at a distance, from place 10
place, by successive regenerations, without
ever being reproduced spontaneously outside
Of man.
Adopted unanimously, except by NJ. Coop
EVE, who declined voting.
xxx. What are the vehiclesof the gen.
erative principle Of cholera?
Under the name of vehicles, the Commits
sion intends to speak merely i5f the agents
by means of which the morhi6c principle
penetrates the organism. To shis question
the facts reply that the air is the principal
vehicle of the cholera principle.
The action Of the cholera miasm is SO much
the more sure as it operates in a confined
atmosphere and near the focus of the emis-
sion. It seems that it is with
cholera miasm as it is with the miasm of
typhus. which rapidly loses its power in the
open air at a short distance from its starting
point.
XXX. To what distance from a focus of
disease can the principle Of cholera be trans
ported by the atmosphere?
The surrounding atmosphere is the princi-
pal vehicle Of the generative agent OF chOl-
era but the transmission of the disease by
the atmosphere, in an immense majority of
cases, is limited to a space very near to the
focus of the emission. As for the facts cited
of transportation by the atmosphere to the
distance Of one CT more miles, they are not
sufficiently conclusive.
Adopted unanimously, except BY Nj. Good |
EVE, who declined voting.
XXM. Independent of the air, what |
other vehicles are there of the cholera prin- |
ciple?
Water and certain ingesta may also serve |
as vehicles for the introduction into the or
ganism ofthe egeneratiyeprinciple of cholera.
This granted, it follows SO to speak, ne |
cessarily, that the passages by which the |
toxic agent penetrates into the economy are |
principally the respiratory passages and very |
probably also the digestive canals. As for |
its penetration by the skin nothing tends to |
prove it.
Adopted unanimously.
XXXII. What are the principal recepta- |
cles of the cholera principle?
The matter Of cholera objections being |
incontestibly the principal receptacle of the |
merbifc agent, it follows that everything |
which is contaminated by the discharges be-
comes also a receptacle from which the gen.
erative principle of cholera may be olsen
gagged, under the influence of favorable con- |
ditions; il follows, also, that the origin Of
the cholera germ takes place very probably |
in the digestive canal to the exclusion, per- |
haps, of all other parts of the system.
Adopted unanimously.
XXXIII. What is the duration of the |
morbifc activity of the generative principle |
Of cholera?
1t results from the study of facts that, in
the open air, the generative principle OF
cholera loses rapidly its mOrbihc activity, !
and that this is the rule; but that under GER
tain particular conditions Of confinement |
this activity may be preserved for an unlim- |
tied period.
Adopted unanimously.
Finally, the Commission adopts the fol- |
lowing formula
Observation shows that the duration of |
the choleraic diarrhea, called premonitory |
which must not be confounded with all |
the diarrheas which exist during the time Of |
cholera-does not extend beyond few days. |
Facts cited as exceptional do not prove |
that the cases of diarrhoea prolonged beyond |
that period belong to cholera, and are sus-
ceptible of transmitting the disease, when |
the individual affected has beer withdrawn |
from all cause of contamination.
Adopted by fourteen votes against four, |

SALvAToRI M. MoNLAU declined voting. |
