the patient was received in the hospital. The termination re- 
cords the status of the patient at the time the entire series of 
observations was concluded. It was necessary to record them 
thus, because several patients remained in the hospital after the 
work was completed and others were transferred to other institu- 
tions and thus passed out of our control. 
By physical development should be understood the condition 
presented to the physician on admission — that is to say, the gen- 
eral physique and nutrition of the patient as brought out in the 
usual physical examination. 
Circumstances made it impossible for us to make an exact 
determination of the mental development of these children, such 
as the application of the Binet-Simon test. The mental fitness 
of each child was simply appraised after watching its conduct 
with its toys and with the other children in the ward, the readi- 
ness with which it answered questions, and its general ability 
to talk, walk, and otherwise behave in harmony with its age. 
In later work it would probably be found desirable to enlist the 
cooperation of a specialist in child psychology, or, failing that, 
it might be found convenient to use the Standard Score Card 
for Babies as outlined by the American Medical Association. 
This has already been employed in an interesting series of obser- 
vations on Filipino children by Albert and Arvisu.(2)
