techial
kind, as being apt to heat too much, and to hasten the
Dissolution and consequent Putrefaction of the Blood.
However, I cannot help thinking that they are the best
Remedies we can use on some particular Occasions, even in
this Fever; for we have no Remedy which gives such a sudden
and brisk _Stimulus_ to the Fibres as they do. And I have
known many Cases of Patients who were extremely low, and
whose Pulse was scarce to be felt, and others who were apt to
fail into fainting Fits, who have been preserved by large and
repeated Doses of these Salts, and the free Use of Wine, and
acescent Liquors, to correct their alcaline Acrimony in the
Blood. Though as soon as such Patients had recovered from
this low State, I laid these Medicines aside; because I
cannot help agreeing with the Doctor in the Belief, that
their continued Use will produce the Effects he mentions. For
although it be true, that these Salts, when mixed with
putrescent Liquors, or with dead animal Substances, resist
Putrefaction, and, like ardent Spirits and Vinegar (the other
Products of Fermentation) check and put a Stop to that very
Process which produced them: Yet it is also true, that, when
mixed with the Blood of living Animals, they stimulate the
Vessels, and increase the Heat and _Momentum_ of the Blood,
and dissolve it; and therefore I cannot but disapprove the
continuing their Use longer than is immediately necessary.

At _Bremen_ there were two Men, one in _January_, and the other in
_February_ 1762, on whom the Cortex had but little Effect, who
recovered by the free Use of Mixtures, with the _confectio cardiaca_
and _rad. serpentariae_, and of Wine, with the Application of large
Blisters. Several Cases of this kind occurred in the Hospitals, where
the Bark did not answer.

There is one thing to be observed with respect to Malignant Fevers,
which is, that if ever they appear in large crowded Hospitals, unless
we can thin the Wards, and procure a free Circulation of Air, and keep
the Hospital and Sick extremely clean, the Fevers will continue to
spread, and great Numbers will die; and even the most efficacious
Remedies will have little or no Effect. And that when once the
Infection is grown strong, it requires the greatest Care, and some
Time, before it can be entirely got the better of. And that if a great
number of Men, ill of this Fever, be ke
