I. Incised wounds were made in the lumbodorsal aponeurosis of the rabbit.2. After varying periods of time they were exposed, opened, and re-sutured.3. At the same time fresh incised wounds were made on the opposite side and re-sutured.4. After an interval, the tensile strength of the re-sutured wounds was tested against that of the fresh wounds.5. The mean tensile strength of the re-sutured wounds was greater than that of the fresh wounds at all intervals of time.6. The maximal 'acceleration' effect was seen when the interval between the wounding and re-suture was 21 days.

I. Ten cases presenting at operation with a mass and an ulcer in the ci~cum are described.2. Nine cases were clinically indistinguishable from acute appendicitis. 3.Five were proved to be inflammation in a diverticulum of the caecum and 4 further cases were probably inflammation in a solitary diverticulum. 4.The presence of ulceration occurring in inflammation of a diverticulum is described.5. The literature is reviewed and the similarity of presentation of acute ulcers of the caecum and inflammation of a solitary diverticulum of the caecum is demonstrated and evidence in favour of a common aetiology is presented.6. An attempt is made to describe the points of differentiation from a carcinomatous ulcer. 7. A conservative approach is advocated.

Antithrombin III is the major physiological inhibitor of thrombin, and congenital deficiency of antithrombin III is associated with increased risk of venous thrombosis either spontaneously or following trauma, surgery or pregnancy. The successful use of antithrombin III concentrate during and following surgery to prevent venous thrombosis is described in a previously asymptomatic man with familial antithrombin III deficiency.
