posures were made on the black asphalt roof of the laboratory. 

 On the first days, during the exposures, the monkey was chained 

 to a scantling which rested upon the roof, but in the last and 

 hottest months it was chained to a wire, so that it rested directly 

 upon the roof. Table VIII, which gives the highest daily maxi- 

 mum temperatures observed in this monkey in the five months, 

 brings out the progress and degree of acclimatization of this 

 monkey to the combined meteorological factors plus the intense 

 heat from the roof — in other words, to the Manila climate at 

 its worst.
