We must not here pursue this subject further. We have endeavoured to sketch certain extensions of the views of Mr. Abernethy, and can only refer the profession and the public, for the facts and arguments which demonstrate and illustrate them, to those works in which they have been enunciated[34]. They have now been subjected to severer trials, and abundant criticisms. So far as we know, they have not been shaken; but if there be any merit in them, if they shall have made any nearer approach to a definite science, or sketched the proofs that Induction alone can place us in a position to talk of science at all, _they are still sequences which have been arrived at by a steady analysis of Abernethy's views_. It was he who taught us, in our pupil days, first to think on such subjects; to him we owe the first glimpse we ever had of the imperfect state of medical and surgical science; and if we do not wholly owe to him the means by which we conceive it can alone be rendered more perfect and satisfactory, he has at least in part exemplified the application of them. If we have made some advances on what he left us, and added to his beautiful and simple general views, something more definite on some points, something more _analytical_ on others,—still, inasmuch as they are clear deductions from the views he has left us, and from such views alone, such advances remind us that the study of his principles serves but to demonstrate their increasing usefulness, and to augment the sum of our obligations. SECTION. Mr. Abernethy's book "On the Constitutional Origin of Local Diseases" had an extensive circulation, and excited a great deal of attention from the public as well as the profession. As a work which may be read as it were in two days, so as a person read it with one or other subject, it produced a great variety of impressions. It may be read simply as a narrative of a number of facts, with the inferences immediately deducible from them. All this is plain and intelligible at once to anybody, and of great practical value; but the work contains numerous observations of a suggestive kind, which require careful thought, and some previous knowledge, to enable a person to estimate their value, or to trace their onward relations. The impression made by the work on different minds varied, of course, with the reader, his information, and, in some sort, with the spirit in which it was studied. Some, who had, in their solitary rides, and in the equally solitary responsibilities of country practice, been obliged to think for themselves, recognized, in the orderly statement of clearly enunciated views, facts and principles which they had already seen exemplified in their own experience, and hailed with admiration and pleasure a book which realized their own ideas, and supplied a rational explanation of their truth and value.
