A number of rice-grains from the samples left at the Jodrell 
Laboratory by Dr. H. Fraser, Institute for Medical Research, 
— Lumpur, F.M.S., have been examined, with the following 
results,— 
Untreated padi, padi after soaking, and padi after soaking and 
V-XV 
XII, and it appears to contain practically no oil. It seems pro" 
bable, therefore, that, when rice is stored for some time, a great 
part of the oil may be removed, in consequence of mites, &e,, 
feeding on the aleurone-layer. 
In some of the cases in which the aleurone-layer was fragmen- 
tary (X, XI) it was found that a few fungal hyphae were 
occasionally present in cells of the aleurone-layer, but these hy phae 
were not abundant, and were probably of no particular significance. 
In X, XI and XII, of such aleurone-cells as were present, many 
contained only a very little oil.
