is the conclusion to be drawn that it would possess sufficient 

 activity, but that this activity would be present in a very 

 high degree. 



This latter fact has now actually been proved by experi- 

 ments on four diseased birds which were fed with the rice 

 in question. This was all the more astonishing because we 

 had here to do with a kind of rice almost entirely deprived 

 of its silver-skin. 



Three of these test-animals recovered within 24 hours. 

 The fourth bird, which was extremely ill, certainly required 

 somewhat longer than one day for its complete recovery, 

 but to an attentive observer it was evident that there were 

 unmistakable signs of improvement almost immediately after 

 this rice had been given, and these signs were sufficient 

 proofs of its powerful activity. 



This example shows at the same time very clearly that 

 there are kinds of unpolished rice to be obtained which in 

 appearance and taste differ little, if anything, from entirely 

 polished rice, and which still oi ve more than sufficient protection 

 against beri-beri. That we insist on such kinds of rice being 

 furnished to us cannot therefore be considered as unreasonable 

 or exaggerated. 



The rice in question is called by the natives in Krawang 

 padi or bras "Benong". 



Though these latter experiences could still be shortly 

 touched upon in table IX, it was not possible to insert them 

 in a suitable manner in the text.
