18. _Dr. Broussais._--While the opinions of this celebrated reformer have been gradually becoming more extensively known among our countrymen, the war has prevailed with increased heat in his native land. The most vehement attacks are made, from various quarters, upon his system of _medicine physiologique_. No one appears to deny that he has clearly proved the existence of mucous gastritis and enteritis in many or most fevers, or the propriety of directing a part of the remedies to them. Criticisms and invectives are freely emitted: but they are only levelled against the too extensive application of this doctrine, and the inconsistencies, unquestionably often real, of the system of which he has made it the foundation. Indeed, if the quotations given are correct, we think no one who has not assumed a party, can refrain from concurring in their condemnation. "Those who understand our doctrine never attack it; they speak of it only to express their admiration: above all, they never think of wishing to modify it, because they know that its fundamental dogmas are unshakeable." "Surtout ils ne s'avisent jamais de vouloir la modifier," &c. A man who assumes such ground as this, had need be very careful in assuming his positions, indeed; and should particularly avoid any thing like self-contradiction. The _Lettres a un medecin de province_, in a style of lively criticism, labour to show a great variety of inconsistencies in this immoveable doctrine. The review of this publication in the Revue Medicale, including copious extracts, coincides with, and evidently wishes to aid, the author's satire. In the same journal are a series of criticisms on some of the elementary propositions of Dr. BROUSSAIS, published in a late edition of his Examen; (nearly the same which were published here, some time since, in the American Medical Recorder, having been translated by Dr. ATKINS.) In these critiques, great severity is shown, in dealing with the new dogmas, and the doctrine is treated as one of dangerous tendency; while, at the same time, high praise is awarded to their author, for his discoveries in the diseases of the alimentary mucous membranes. In the other journals, there is a division; some favouring the new opinions, while others oppose them with more or less of vehemence.
