Since the period when Humoral Pathology fell into meriteddisrepute, comparatively few attempts have been made, to definewith any degree of accuracy, the conditions under which morbidsecretions may find their way into the circulation. The diseasesproduced by the presence of vitiated fluids in the general system,and in parts of the body at a distance from their original source,have received more attention; but they are still far from occupyingthat position in our systems of medicine and surgerywhich their importance deserves.
The difficulty of tracing diseased secretions after they havebecome mingled with the blood, or of recognising their presencein the vessels, has rendered the investigation of their actionsoften tedious and inconclusive; while, on the other hand, thechanges of structure in solid parts, readily appreciated by thesenses, have been more calculated to arrest the attention, and toafford that ready solution of the origin of the symptoms which,whether imaginary or real, has a tendency to relieve the mindfrom farther doubt and suspense. Hence it has happened, thatthe pathology of the solid parts of the body has received a verydisproportionate share of attention.
Most of the observations which have tended to advance our[Pg ii]knowledge of the effects of the introduction of diseased fluidsinto the blood, have been recorded under the name of Phlebitisor Inflammation of the Veins; and I have retained this title,althoug
