Now the peculiarity in these cases is, that the internal organs, after death, exhibit no signs of inflammation, unless vascularity be inflammation. The organs which, in ordinary cases, are inflamed, are in these cases turgid with blood. Are the terms debility or adynamia appropriate expressions to designate even this condition of the organs? Just as appropriate as they would be to express the condition of a person who is struck dead by lightning, whose muscles are incapable of contraction, and whose blood will not coagulate. Those who apply these terms even to such forms, and, _à fortiori_, to any other forms of fever, must be ignorant either of the nature of the disease, or of the constitution of the human mind. If they know the disease, they know that the patient appears to be weak because the primary operation of the disease is upon the nervous system—an operation which, as has just been stated, while it disturbs that due and equal distribution of nervous influence which is necessary to the healthful action of the organs, and, therefore, to the general strength of the system, is not incompatible with, but promotive of an excitement of the vascular system, which terminates in inflammation. Debility is the last, the ultimate result of the disturbance of the functions of a certain series of organs, but part of this very disturbance of function, and a most important part, a part which exerts the greatest influence over the progress of the disease and the life or death of the patient, consists not in the weakened, but in the augmented strength and the increased activity of the vascular system. To designate the ultimate result upon the system by a term which gives an entirely false view of the individual processes in the economy, by which that ultimate result is produced, must, we repeat, arise either from an ignorance of the true nature of those processes, or from not reflecting on the influence which words exert over the manner in which the human mind conceives of things. For the sake of the progress of the science of medicine, for the sake of rendering the language of medicine the correct expression of the knowledge which the science has actually attained, and, above all, for the sake of accomplishing the great object of medicine, the preservation of human life, it is high time that these terms with which physicians have so long allowed their minds to be abused, should be banished from medical nomenclature, or, at any rate, from that part of its nomenclature which appertains to fever.
