THE HEAD
The head exhibits certain noteworthy features. Excessive perspiration when sleeping is an early symptom of rickets. It must be remembered, however, that any debilitated child may perspire more or less when asleep. Both in rickets and in hydrocephalus (water on the brain) the face seems small and the head large, but in the former the head is square and flat on top, while in the latter it is of a somewhat globular shape. The fontanelle is prominent and throbs forcibly in inflammation of the brain, is too large in rickets and hydrocephalus, bulges in the latter affection, and sometimes sinks in conditions with only slight debility.
