ON THE CLASSIFICATION OF CULTIVATED RICE. 25 
collected and sent him these samples, which amounted to one thousand 
and twenty four. The writer wishes here to express his sincere thanks 
to him for his kindness. 
The classification of Burman rice by the writer according to the 
shape and size of the hulled grain is as follows :— 
(L.=Length ; B.=Breadth.) 
( 1) Slender grained = 
der grained. —5->3 
GE) Large. L. over 7.5 m.m. and B, over 2.5 m.m. or L.xB.>18.75 s.m.m. 
(2) Medium. Those belonging neither to the large nor to the small grain. 
(3) Small. L. under 7.0 m.m, and B. under 2.2 m.m. or L.x B.<15.40 s.m.m. 
ä T 
(IL) Long grained. ana 
(1) Large. L. over 6.5 m.m. and B, over 3.0 m.m. or L.x B.>19.5 s.m.m. 
(2) Medium. Those belonging neither to the large nor to the small grain, 
(3) Small. L. under 6.0 m.m. and B, under 2.5 m.m. or L.x B.<1.50 s.m.m * 
(III) Short grained. 2> = 
EN) Large. L. over 6.0 m.m. and B. over 3.0 m.m. or L.xB.>18.0 s.m.m. 
(2) Medium. Those belonging neither to the large nor to the small grain. 
(3) Small. L. under 5.5 m.m. and B, under 3 m.m. or L.x B.<16.5 s.m.m. 
The important physieal properties of the unhulled and hulled grain 
of 971 varieties of Burman rice, which the writer has examined with 
the help of K. Taniaucnt, then assistant to our laboratory, and classified 
according to the above standards, are shown in the table in the appendix. 
The following table shows how the product of the length by breadth 
of the hulled grain harmonizes with its real volume, in average of each 
form of Burman rice grains, of which the length, breadth and volume 
were measured.
