This is an exceedingly painstaking and thorough study based on phlebitis and its sequences appearing in 225 of 3,000 patients after they were operated on for a wide range of diseases by Professor Ducuing at Toulouse. The ratio 10.5 per cent for 1,500 abdominal operations, 6 per cent for 750 operations on the external genital organs and perineum, and 1.8 per cent for 750 operations on the head, neck, thorax and extremities averages 7.5 per cent for the 3,000 operations. All bloodless operations, such as reducing dislocated or broken bones, are omitted. The anatomy and physiology of veins in practically all parts of the body, the pathology of phlebitis and of its sequences, the symptoms, diagnosis and prophylaxis, as well as other forms of treatment, are all discussed minutely with a fine discrimination for orderliness and allotment of space. Throughout the work there are frequent references to published reports and
