During the years from 1920 to 1939, inclusive, 133 patients were admitted to the Children's Memorial Hospital with the diagnosis of intussusception. In every instance the diagnosis was proved either at operation or necropsy, with 15 exceptions, which will be discussed further. Tables 1, 2, 3 and 4 are self explanatory and show some of the pertinent facts concerning the entire group.

He procured a reduction in 60 per cent of his patients by this method with only one perforation of the bowel in more than 300 patients. The chief criticism of the method used by Hipsley is that one cannot be certain that reduction of the intussusception has occurred following the enema. Then, too, this method would seem to
