on sucli an occasion, and in such a man, ought not to be visited by heavy censure. Indeed, I am convinced that every unpreju- diced reader, qualified by the study and practice of auscultation to judge of the character of his work, (and none else are qualified,) must confess that the author stands in need of less indulgence on this point than could have been expected ; certainly less than every candid and honourable mind will be ready to concede. To estimate fairly the correctness of M. Laennec's statements, we ought, also, to take into account his vast experience, and his unequalled practical tact, which was the admiration of every one who had opportunities of observing his examinations. In no case, even the most obscure, did he shrink from pronouncing his opin- ions, and fixing his diagnosis; and rarely indeed was he mistaken. These circumstances ought to make his successors long hesitate before they call in question the correctness of his statements, even although they should fail to verify them by repeated experience ; and incline them rather to doubt their own capacity in exploring, and the accuracy or acuteness of their perceptive powers, than the fidelity of the records which he has bequeathed to them. And here I think it necessary to state, in the most distinct and unequivocal terms, that although nothing is easier than for any one to acquire sufficient evidence of the truth and powers of Auscultation, it is only by long and painful trials, (inter tcedia et labores, as Avenbrugger says of his congenerous discovery,) that any useful practical knowledge of it can be acquired. When, therefore, we hear, as we sometimes do, that certain persons have tried the stethoscope, and abandoned it upon finding it useless or deceptive ; and when we learn, on inquiry, that the trial has ex- tended merely to the hurried examination of a few cases, within the period of a few days or weeks ; we can only regret that such students should have been so misdirected, or should have so mis- understood the fundamental principles of the method. No con- clusions deduced from such attempts—I cannot dignify them with the term experience,—can have any weight with those qualified to judge in the matter; they can only be added to the heap of false facts, as they have been called, with which medicine, and indeed every department of human knowledge, is overlaid, and which are the characteristic and ready offspring of minds too feeble to be habitually conversant with general principles and
