Tlie rice grain i.s a complex strncluic loi lueJ of a great many distinct parts, 

 sonic of whicli can be readily parteil by ordinary meehanical appliances, whilst 

 others can only Ix; separated by special means. Of the former is the hard onter 

 coat, ilFclf composed of several dill'erent parts, which is generally removed by 

 the farmer as chalY before the rice is sent into the market. The hulled grain, in 

 the form in which it is bonght for foo<l consists of three easily discernible parts, 

 a thin, yellowish skin on the (»ntside (the testa), within this the while starchy 

 matter which constitutes the nutritions part of the grain (the endosi)L-rm), and at 

 the lower end a portion of a dilTerent appearance, usually horny and shrivelled 

 looking (the embryo). Immediately below the tesla the cells of the endosperm 

 ilo not diller in general appearance from those in the interior, but the greater 

 part of tlie albumenoid matter of tlie endosi)erin is ticcumulated in these cells. 

 An excellent test for the presence of albmnenoids is mercuric nitrate ; if a section 

 of a grain of rice be steeped in such a solution lho.se portions which contain 

 albniuenoid matter l>ecorae coloureil red, whilst the rest of the grain remains 

 mico'.onred. When a thin slice of the unwhitened grain is thus treated tin; 

 cells forming the testa have a s-omewhat greenish colour and can be sharply 

 distinguished from liie layer inime<liately within, which is deeply coloured 

 red. This coloration extends inwards for a distance a little greater than the 

 tliickncss of the testa, but tlic foim of the cells thus coloured does not appear to 

 be dillerent from the remainder of tiiose forming the endosperm, and which 

 a-^sumc no coloration. In a similar section of whitened rice the outer layer of 

 greenish, sijnare cells is not seen, and the edges present a jagged appe;vraiice, but 

 the outer cells are as strongly coloured red as liefore, showing that oidy a small 

 jKjrtion,' if any, of the cells containing nitrogenous matter luus l)een removed. 

 In fact, tlie f hickness of the layer coloured red cannot Ik; said to have perceptibly 

 diminished. The red coloration is not uniform l)nt is ilistributed over numerous 

 points, iK'inu stronger near the tesla and b-'.Mn)in'.i fainter away from it ; under
