That the doctrine of gastritis has made a great impression at Paris, that almost every one believes in it, to a greater or less extent, appears undeniable; but there, as well as here, most of the more rational, and moderate minded men are evidently of the only school a physician ought to belong to, the _eclectic_. Borrowing largely from BROUSSAIS, and having had their minds powerfully stimulated by the succession of striking and novel ideas which he has introduced, they think it unmanly to "bind themselves to his chariot-wheel," but form conclusions for themselves from every resource within their power. If the great French reformer really wishes to establish as absolute a power over the minds of his followers, as MAHOMET or PYTHAGORAS did, and as the above-quoted extract seems pretty fairly to indicate, he must certainly undergo many mortifications. Notwithstanding the "inebranlable" nature of his dogmas, M. MIQUEL has furnished us with several variations from them, in the writings of Messrs. BOISSEAU, ROCHE, SANSON, REMUSAT, RICHOND, and BEGIN; and the last-named individual has had a public dispute with his preceptor. M. BEGIN has produced his promised work on surgery, according to the principles of the new school. We have not seen the volume, but have read a review of it in the Revue Medicale, by M. BELLANGER. The latter describes it as a cursory work, having for its object the adaptation of surgery to a set of general principles, rather than a detailed system of instructions how to proceed in each individual case. It contains only what is easy to be remembered, and omits those matters for which it is usual to refer to books. Thus two pages only are appropriated to fractures of the body and neck of the femur! and twenty-six for the whole subject of fractures, wounds, and six or eight of the most important diseases, of bones! Yet all this criticism is not without a compliment, well-merited at least by the former productions of the same author, to his talents and ingenuity. 19. _Whooping-cough._--"There is no disease of children, in which the resources of medicine are more manifestly serviceable than in an obstinate whooping-cough." Such, in amount, was the opinion of Dr. UNDERWOOD, and Dr. WATT uses language almost equally strong. Certainly, we are not at all times equally successful or equally sanguine in America. Dr. A. CAVENNE considers whooping-cough a true bronchitis, a pulmonary catarrh; accompanied with greatly heightened nervous symptoms, owing to the irritable period of life at which it occurs, and particularly to its frequent existence in nervous constitutions. Professor TOURTELLE calls it a pneumo-gastric, pituitous catarrh; and certainly, the pupils of a modern school will find no difficulty in recognizing symptoms of gastritis in its severer forms. The further inferences drawn by Dr. CAVENNE, are as follows:
