    It will be seen from the following table that one of the chief causes of the low rate was the decrease in mortality from respiratory diseases.

The heart condition in 810 of these children was found to be normal, and in 272 there was evidence that the heart was affected. It should be noted that "no swimming" is not classed as a restriction since practically all these rheumatic children are forbidden to swim for a time after their return from hospital.

The Table would be of greater value if distinction was made between complete and incomplete tonsillectomies but it was found that insufficient material existed for making this sub-division. One's impressions certainly are, however, that whilst a completely tonsillectomised rheumatic child is better off than his non-tonsillectomised brother, he will be better off with his tonsils intact (even though they be unhealthy) than with tags remaining after an incomplete operation.
