PAKKIA EOXBURGHII 107 



they remove the crusts that shield the acari. The treatment is 

 successful in direct proportion to the energy of rubbing. 



The seeds of " gogo " are very large, lenticular, flattened, 

 3-4 centimeters in diameter. Their chemical composition has 

 been studied by Pettit. Alcohol dissolves the active principle, 

 perhaps a glucoside, the study of which the author has not 

 completed. Five centigrams of this substance administered to 

 a guinea-pig causes paralysis of the hind quarters without any 

 apparent inflammation. He also found saponin in the seeds, 

 but it exists in much greater quantity in the trunk. In the 

 Sunda Islands they eat the seeds roasted and also extract from 

 them an illuminating oil. 



The maceration of gogo is emetic and purgative ; it is used 

 in the treatment of asthma; it is exceedingly irritating, the 

 slightest quantity that enters the eye causing severe smarting 

 and a slight conjunctivitis for one or two days.
