The most noticeable 4 mei of this rice is its unusual richness in 
albuminoids and in Some of the most highly esteemed of the 
Japanese glutinous ie have indeed been found to contain from 14 to 
2 per cent. of oil, instead of the 0*4 or 0*5 per cent. commonly present 
in Carolina rice, but then they are comparatively poor in albuminoids. 
In the sample now under discussion it was found that the coagulable 
albuminoids, as determined Py the n method, amounted to 8*5 pe 
cent, a figure which is only 0-7 per cent. lower ihan the proportion 
recorded in the above analysis, and whieh still compares favourably wit 
the average, namely, 7:3 per cent., present in other Indian rices. 
it must be remembered that a similar reduction (say 0°6 per cent.) 
mus * be made in the latter figure, in order that a fair comparison 
between the two per-centages may bs made. The numbers will 
then be—

One of the results of this richness in albuminoids is brought out on 
calculating the nutrient ratio of this Burmese rice, which is much nearer 
to that of a complete food than is the case with the common kinds of 
Indian rice. ie i are likewise rather poorer in phosphoric acid 
than the Burmese variety.
