This review is entirely up to date and its main conclusions can only be reemphasized; namely, the difficulty of differentiation between arterial embolism and thrombosis; the utmost urgency in the treatment of arterial occlusion; the transportation of all such cases to surgical centers, where experienced surgical help can be secured; the place of antispasmodics, procaine hydrochloride block, sympathectomy, embolectomy, arteriectomy and amputation in the various stages of arterial embolism. The presentation is brief, concise and quite didactic. The American reader would welcome a few illustrations and case reports. The teaching value of this monograph to students and the general practitioner is unquestionable.
