1 The remainder (1.26 per cent) consisted of imperfect seeds and waste. 
2 The mesocarp is the sugary pulp, which on drying adheres to both the outer pod and capsule. 
3 Contained a irace o' tannins. 
' Albuminoia°nitro r gen, r as determined on the kernels by the official (Stutzer) method, constituted 86.28 
per cent oi the total nitrogen and was equivalent to 56.23 per cent of albuminoid protein. 
6 Starch was entirely absent.
