I. Of 91 cases of active tuberculosis 50 yielded haemagglutination titres of I: 16-1 : 128, 14 gave a titre of 1: 8, and the remaining 30 yielded titres of 0-1: 4. 2. Of 119 normal persons, 101 yielded titres of 0-1 :4,14 gave a titre of I: 8, 3 a titre of I: 32, and I a titre of 1: 128. 3. It would appear that a positive haemagglutination result (a titre above I: 8) is significant, and a titre of 1: 8 or below may occur in a high percentage of cases of active tuberculosis. 4. There appears to be little correlation between the erythrocyte sedimentation rate (Wintrobe) and the haemagglutination titre in individual cases of active tuberculosis. Work is in progress on the correlation of the haemagglutination titre and erythrocyte sedimentation rate in cases under treatment.
The clinico-pathological features of inguinal hernia in infancy have been discussed. It is suggested that these hernias should be classified as complete and incomplete and that other terms that only give rise to confusion should be abandoned. When the sac contains fluid only it should be referred to as a fluid hernia. It has been emphasized that strangulation can and does occur during infancy. Irreducibility should be regarded in the same serious light as it is in adults and taxis should never be attempted. Treatment has been discussed and it has been pointed out that herniotomy between the ages of 3 and 6 months is desirable in the majority of cases. Fifty consecutive cases treated at the Groote Sehuur Hospital have been reviewed briefly.
