ARON. 



of a puppy, for nearly one year, while its weight at the end of the year 

 should be three times as great. If such an animal is thereupon fed 

 amply, it fattens and rounds out, but does not reach the size of a control 

 animal which from the beginning has been normally fed. It is unable 

 to make good the growth suspended by the long restriction of food. 



The "growth" principally depends on the tendency to grow pos- 

 sessed by the skeleton. The skeleton loses its capability of growing 

 in more advanced age regardless of the size which the animal has reached. 



I wish to thank Mr. Pio Valencia, formerly demonstrator in phy- 

 siology, for his kindness in watching the animals when I was absent from 

 Manila.
