who, for the first few years, would have almost certainly followed the practice of their instructors, compute the number of those of the lame who, under Providence, have walked in consequence of the clear-sighted reasoning of Abernethy. How the French surgeons may have been influenced by Abernethy on this subject, I do not know. When I was first in Paris, in 1824, they were divided; but I recollect Baron Larrey showing me a case which he regarded as a clear example of this fracture in course of firm consolidation, and he was well aware of the opinion of Abernethy. The bearing which Abernethy's acuteness of observation of the influence of the state of the digestive organs on so-called specific poisons in producing or maintaining diseases resembling them, opposed as it was to the most powerful conventionalism, is a proof of his clear judgment; and, if we mistake not, will one day prove to have been the first ripple of a most important law in the animal economy, which will shed a light as new on specific affections as his other principles have on diseases in general. His treatment of that severe malady, "lumbar abscess," is, in our view, a most acceptable addition to humane and successful surgery; and as regards one of its distinctive characters, he has, as we have shown, received the encomiums of the most distinguished of his contemporaries, including Sir Astley Cooper. The manner in which he applied that law which prevails in voluntary muscles to the replacement of dislocations—namely, that muscles under the influence of the will cannot ordinarily act long and unremittingly—was an amendment as humane as scientific; and, whilst it has removed from surgery a farrier-like roughness in the treatment of dislocations, as repulsive as unnecessary, it has adjusted the application of more sustained force, when it becomes necessary, on principles at once humane, safe, and effectual. In short, whatever part of surgery we consider, we should have something to say of Abernethy—either something new in itself, or improved in application. We find him equally patient and discriminative, wherever there is danger; thus there is the same force and originality on the occasional consequences on the simple operation of bleeding in the arm, and the more serious proceeding of perforating the cranium. He is every where acute, penetrating, discriminative, humane, and practical; so that it is difficult which most to admire, his enlarged views in relation to important general principles, or the pervading science and humanity with which he invests their minutest details.
