MARCH increase in deep venous flow occurred in 2 of the 4 patients. Our present technique of stimulation may not produce repeatable calf-muscle behaviour in each subject; in addition, the autonomic nerves supplying blood-vessels may be affected by stimulation. Further evaluation of this method for increasing venous flow is in progress. SUMMARYA technique for recording blood-flow in the veins of the lower limb is described. The method is suitable for use in conscious subjects and during operation.Studies of deep venous flow have been carried out on 14 patients. In subjects premedicated prior to anaesthesia mean flow in the external iliac vein was 434 ml. per minute and in the region of 170 ml. per minute in the popliteal vein. Immediately following anaesthesia induced by thiopentone, these flow rates were reduced by at least 50 per cent and remained low throughout operation. A preliminary investigation has been made of the effectiveness of several possible methods of increasing flow in the deep veins during operation as a preventive measure against deep-vein thrombosis.Acknowledgements.-We are indebted to Professor J.

CONCLUSIONSSet against the vast experience, the careful documentation, and the brilliant writings of such as Gordon Taylor (1953) and Ogilvie (1944a, b) in World War 11, the series we have described appears slight. We have felt it worthy of record in that each campaign has some peculiarities and, moreover, it is rare to find younger surgeons familiar with the literature of war. Battle surgery continues to evolve although at a slower pace than previously; we have attempted to outline some of the factors which made it in 1967 more easy in some respects, but more difficult in others, than it was a quarter of a century ago. It is to be hoped that others will supplement our experience and confirm or confute the methods we have used.Acknowledgements.-It is a pleasure to record our thanks to the nursing sisters whose skill and devotion in operating theatre and acute care ward contributed so much to the survival of our and their patients; to Dr. M. J. Robinson, the team's paediatrician, who supported our surgical efforts in many directions; to Mr. R. Lawson and Mr. M. Smith for permission to include patients treated by other surgeons in the team; to Mr. Graeme Grove for much encouragement, and to the members of the Walter Reid Surgical Research Team and 3rd United States Army Surgical Hospital for stimulating advice and information.

The treatment of haemorrhoids by cryosurgery is fairly new. One hundred cases have been analysed and the results presented as a preliminary report. Although the maximum follow-up is only 18 months, so far the results have been encouraging, and should they be maintained this method of outpatient haemorrhoidectomy could dramatically alter the management of this condition.

A case of peripheral sensorimotor neuropathy associated with seminoma of the testis is described. The literature on the subject is reviewed including a classification of the neuropathies. Finally, because the neurological symptoms may well be transitory they should not be regarded as a contra‐indication to treating the primary neoplastic process.
