freely, the cholera is also found to abate quickly, and sometimes very
greatly. The inference drawn from these facts has been that the
prevalence of cholera is largely owing to a lack of electricity in the
atmosphere, and consequently to a want of the animal electricity or
electro-vitality in the system of the patient; and thence it might be
concluded that cholera implies a negative condition of the system. I
think there is a fallacy in this reasoning. There appears to me to be an
unwarrantable assumption in confidently attributing the long absence
from the heavens of marked electrical phenomena, and the failure of the
electric machine to give its spark, to an unquestioned deficiency of
atmospheric electricity. Electrical manifestations take place only when
the _plus_ and _minus_ conditions are existing, in relation to each
other, somewhat near, or not very remote; and the visible phenomena
appear when the positive and negative rush together, so as to produce a
polar equilibrium. But suppose a _plus_ condition to exist over a wide
region, then, everything being _overcharged_, the visible phenomena
would be as rare and as difficult of attainment as if all around were
negative. How, then, can it be inferred, with any certainty, from such
data, that there is a _deficiency_ of electricity, rather than an
_excess_ of it?

I have not treated a case of cholera; but my own impression of it is,
that in the first stage, or during the "rice-water" discharges, the
condition of the system is, as in other acute affections, excessively
positive; but that, as the collapse comes on, it rapidly subsides into
an intensely negative state, thus assuming the chief characteristic of a
chronic condition.

In the above remarks, I would not be understood to indicate any doubt
that the prevalence of cholera is often aggravated or mitigated by
peculiar electrical states of the atmosphere. It appears altogether
probable that such may be the fact; and I should presume that electrical
treatment, properly administered, would be found eminently successful in
this fearful malady.

Again, in _chronic rheumatism_ there might, at first view, seem to be
frequent exceptions to the rule last above stated; but the cases alluded
to are not such. It is often the fact, during chronic rheumatism, that
soreness and severe pain are felt, especially under the presentation of
the negative pole, thus showing that these points require to be treated
with the
