An attempt was made to determine whether the Reltan-Halstead Organic Test Battery separates neuropsychiatric hospital organics from schizophrenics. The battery was administered to 25 schizophrenics and 2$ cerebral-lesion organics at each of 2 chronicity levels. Only 1 of the 24 diagnosis/Diagnosis X Chronicity effects used to evaluate the data was significant at the .05 level, indicating that actuarial application of Reitan-Halstead scores is of no practical value in the separation of the 2 groups. To determine whether expert clinicians might improve upon the actuarial results, protocols of 24 schizophrenics and 24 organics were sent to 8 Reitan-Halstead experts who were instructed to separate them into brain-damaged and schizophrenic diagnostic groups. The mean number of correct classifications, 25.5 out of 48, suggested that clinical judgment added nothing to actuarial prediction in this case.

M1AR,CH 6J, igi5j~ICAL 413TRENCH 'i FROSTBITE .' BRITISAL 413 of the leukaemic synmptonms was ever brought about. At the post-mortemn examination excess of lymphocytes was found in several org,ans, and the blood throughout retained its leulcaemic aspect as far as the differental count was concernied. At the same time the patient undoubtedly improved enormously coincident witlh the fall in total numlber of hiis wllite cells, and it was not till the septic infection alluded to hiad set in that hiis progress towards apparent recovery was interrupted. CASE III.-Lymtipho-sarcomlia. P. G., aged 65, a farmer, was admitted oni May llthi, complaining of lunmps in his neck and of 'difficulty in breathing and swallowing(. He stated that he had always been a healthy man unitil about seven montlis previously. He then noticed a swellings on the right side of his neck, and shortly afterwards found that his breathing at night was troul)lesome so that he had to sit up in a chair. He also began to be troubled with a !cough,without expectorationandd by hoarseness, and, before admission to hospital cougled inicessantly day anid night. Early in April he found difficulty in swallowing, and couild only get down fluids. On admission enlarged glands were found on both sides of hiis neck. On the right side these were very big, and practically filled up the entire space between the clavicle and the lower jaw; on the left side they were smaller. The veins on both sides were distended. InI the thorax there was an area of dullness over the manubrium sterni, and extending slightly out on each side beyond the sternal margin. This dull area merged below with the cardiac dullness. The breathing was slightly stridulous, and oni auscultation seemed very harsh all over the upper l)art of the thorax. An x-ray examination

THREE cases, all very much alike, were of interest as regards exit wounds in the perineum. The bullets entered from the buttock region or thereabouts. In each case the skin split away from the sphincter margin through its whole circumference, leaving the anus with a small margin of skin isolated (see illustration). This was no doubt due to air concussion distending the loose perineal skin, and then bursting like a paper bag, the sphincter holding tight.-4zlĨ njury to the rectum from bullet wound.Another point of interest occurred in two cases of perforating wounds of the rectum viz., considerable blood effusion in the region of the mesentery of the pelvic colon-an argument in favour of transverse rather than iliac colostomy in cases of rectal wounds.Speaking generally, so far as I have seen, perforating wounds of the rectum tend to do badly because of the severity of the sepsis; and early colostomy with thorough exposure of the entire track (when possible) for drainage seems to me to be imperative.
