The properties of the mechanical, chemical, and hy¬ draulic departments, may be spoken of separately, or they may sometimes be referred to, under the inclusive terms structure, or organization. The life of a seat, in the state of disease, is changed; in conformity with general principles, we may infer that this change is produced by ad¬ dition or subtraction of properties, but we cannot say to what properties the change is to be im¬ puted, or in what the change consists. It has been attempted to limit the varieties of the con¬ dition of life to those of degree, but it most com¬ monly happens in disease, that effects are pro¬ duced, or symptoms exhibited, which cannot be accounted for by any variety in the degree or force of properties of life ; on the contrary, such sym¬ ptoms are generally to be explained only by sup¬ posing the operation of new or different properties, or off-such as are preternatural, in the seat of dis¬ ease, rather than by any variety in the degree of those which are natural. As for example; what degree of a natural property constitutes pain ? (an instance the least favourable.) We can say of pain that it is a modified sensibility ; but to say that it is an increased sensibility, would be just as rea¬ sonable as to say that the infinite perceptions of a sense, as that of vision, are only degrees of the faculty of perception.
