Here is a table showing colour, 

 certain samples examined by Harz :—

A note of different analyses may be found useful. 

 Church, in his " Food Grains of India," gives for the 

 seeds of the Indian variety: — In 100 parts, water, lO'l ; 

 albuminoids, 31-9 ; starch and fibre, 53"9 ; oil, 0"9 ; ash, 3-2. 

 The nutrient ratio is 1 : 1*75, the characteristic being the 

 richness in nitrogenous constituents. 



Harz found the lathyrus to contain 84 per cent, of dry 

 substance, 25 per cent, of proteid stuff, 1-9 per cent, of fat, 

 54"5 per cent, of non-nitrogenous extract, 4-1 per cent, of 

 fibre, 2-9 per cent, of ash. 



The seeds of L. sativus, weisse (so-called dog-tooth 

 vetch), grown on chalky, loamy soil, contained in 100 

 parts of air dry weight : — Water, 12-31 ; ash, 2*19 ; cellu- 

 lose, 4'44 ; starch, 31-10 ; other non-nitrogenous substance, 

 26-42 ; proteid, 23-63. 100 parts of the ash yielded : — 

 Potass, 45-13; chloride of sodium, 2-28; lime, 10-86; 

 magnesia, 3-72 ; iron oxide, 0-44 ; phosphoric acid, 21-86 ; 

 carbonic acid, 9-78 ; sulphuric acid, 4'96 ; silicic acid, 

 0-98. 



CULTIVATIOX. — In India it is sown aljout the close of the 

 rains (October) in heavy clay soils, and on laud hardened 

 through submersion, and occasionally in rice fields before 

 the rice is cut. It may be reaped in March. ]\Iany 

 thousands of acres may be under the crop. Full details
