It took rank at once as one of the most complete and reliable works extant. Six editions have been printed, and others may be expected, for, notwithstanding the appearance of later treatises traversing the same ground in all the light of modern science, it still deservedly maintains its place in public estimation; and, unlike the generality of medical books, gives promise long to survive its learned and lamented author. Clearness, vigor and beauty of style, simplicity of arrangement, fulness and accuracy of description, are a few of its many excellences. Nearly a generation has elapsed since its publication, and it would he strange if, in the rapid progress of inquiry, its pathology on some subjects had not become rather antiquated, and its therapeusis also arraigned, if not partially discarded.
