 measure of damage done to the rice appears from this last 

 table III, as well as from the former, but at the same time, 

 we see how lying still — never being moved about — conduces 

 to corruption and decay. 



IV. Influence of the usual Preservatives used in the Storage 

 of unpolished Rice. 



It has thus been shown that unpolished rice — even under 

 the most favourable circumstances, suited for practical use — 

 is so much sooner subject to undesirable changes than more 

 completely husked and polished forms of rice, so that it can
