man. It may be at a very far-distant period 
that this evolutionary preputial extinction will take place,--probably 
contemporary with the existence of Bulwer's "Coming Race,"--but not 
at a too remote period for the proper and satisfactory tabulation of the 
statistics. 
The ideas of the etiology and pathological processes through which we 
journey,--from a condition of health and good feeling to one of disease, 
miserable feeling, and death,--as described in, or rather as they control 
the sentiment and policy of, this work, are such as have been followed 
by Hutchinson, Fothergill, Beale, Black, Albutt, and Richardson, so 
that if I have totally ignored the old conventional systems, with their 
hide-bound classification of diseases to control the etiology, I have not 
done so without some reliable authority. In studying the etiology of 
diseases we have, as a rule, been content to accept the disease when 
fully formed and properly labeled, being apparently satisfied with 
beginning our investigation not at the initial point of departure from 
health, but at some distant point from this, at the point where this 
departure has elaborated itself, on favorable ground, into a tangible 
general or local disease. As truthfully observed by T. Clifford Albutt: 
"The philosophic inquirer is not satisfied to know that a person is 
suffering, for example, from a cancer. He desires to know why he is so 
suffering,--that is, what are the processes which necessarily precede or 
follow it. He wishes to include this phenomena, now isolated, in a 
series of which it must necessarily be but a member, to trace the period 
of which it must be but a phase. He believes that diseased processes 
have their evolution and the laws of it, as have other natural processes, 
and he believes that these are fixed and knowable." To do this, the 
physician must travel beyond the beaten path of etiology as found in 
our text-books. He must follow Hutchinson in the train of reasoning
that elucidates the pre-cancerous stage of cancer, or tread in the path 
followed by Sir Lionel Beale, in finding that the cause of disease 
depends on a blood change and the developmental defect, or the 
tendency or inherent weakness of the affected part or organ; to fully 
appreciate the inherent etiological factors that reside in man, and which 
constitute the tendency to disease or premature decay and death, we 
must also be able to follow Canstatt, Day, Rostan, Charcot, Rush, 
Cheyne, Humphry, or Reveille-Parise into the study of the different 
conditions which, though normal, are nevertheless factors of a slow or a 
long life. We must also be able to appreciate fully the value of that 
interdependence of each part of our organism, which often, owing to a 
want of equilibrium of strength and resistance in some part when 
compared to the rest, causes the whole to give way, just as a flaw in a 
levee will cause the whole of the solidly-constructed mass to give way, 
or a demoralized regiment may entail the utter rout of an army. As 
described by George Murray Humphry, in his instructive work on "Old 
Age," at page 11:-- 
"The first requisite for longevity must clearly be an inherent or inborn 
quality of endurance, of steady, persistent nutritive force, which 
includes reparative force and resistance to disturbing agencies, and a 
good proportion or balance between the several organs. Each organ 
must be sound in itself, and its strength must have a due relation to the 
strength of the other organs. If the heart and the digestive system be 
disproportionately strong, they will overload and oppress the other 
organs, one of which will soon give way; and, as the strength of the 
human body, like that of a chain, is to be measured by its weaker link, 
one disproportionately feeble organ endangers or destroys the whole. 
The second requisite is freedom from exposure to the various casualties, 
indiscretions, and other causes of disease to which illness and early 
death are so much due." 
In following out our study of diseases, we have been too closely 
narrowed down by the old symptomatic story of disease; we have too 
much treated surface symptoms, and neglected to study the man and his 
surroundings as a whole; we have overlooked the fact that there exists a 
geographical fatalism in a physical sense as well as the existence of the
influence of that climatic fatalism so well described by Alfred Haviland, 
and the presence of a fatalism of individual constitution as well, which 
is either inherited or acquired. The idea that Charcot elaborates, that, as 
the year passes successively through the hot and the cold, through the 
dry and the wet season, with advancing age the human body undergoes 
like changes, and diseases assume certain characteristics, are also 
points that are overlooked; and nowhere is this latter view seen to be
