animals from scurvy for a period of nine weeks. Where the 

 charts show deaths on these diets after a few weeks, post-mortem 

 examination showed the causative factor to be pneumonia. 



3. Fifteen grams of banana each day gave protection from 

 scurvy for a period of nine weeks. 



4 The experiment with lansones had to be terminated after 

 four weeks, because this fruit disappeared from the Manila 

 markets, being no longer in season. A careful inspection of 

 the lansones growth curves shows a steadily decreasing weight, 

 so that 10 grams were evidently insufficient as a protection 

 from scurvy. 



5. Fifteen grams each of kangkong leaves and of camote leaves 

 daily gave protection for a period of from seven to nine weeks.
