[14] This precept, of which the very reverse is but too frequently
practised, is of very great consequence: It is founded upon this, that
a discharge of blood proves that an incision has reached the quick;
now every such incision produces an inflammation, which retards the
suppuration already begun, and hence we interrupt this operation of
nature which we meant to promote, and, as it is the means of preventing
a mortification, whatever interrupts it contributes to the disease: It
cannot, therefore, be too often repeated, that in general, incisions
which cause a discharge of blood, ought never to be practised after a
suppuration is begun. TISSOT.
