“From the foregoing analyses it will be seen that both descriptions of earth nut are exceedingly rich in flesh-formers, and that they contain a moderately large amount of oil. They also possess a sweet agreeable flavour, and are, I believe, very digestible. As these may, I am informed, be bought at from £6 to £8 per ton, it is evident that farmers would do well to give earth-nut cakes a trial in the feeding of their stock.
“Pure linseed cake does not contain starch, but in its stead mucilage. The feeding qualities of starch and mucilage are, however, very similar.”
ARAROBA. Syn. Araroba powder. Bahia powder. Goa powder. The pith or medulla of the stem and branches of a leguminous tree (a species of Centrolobium) growing in Brazil. It is in extensive use amongst the natives of India, who employ it in affections of the skin. It has been applied with success in shingles and ring-worm, in the form of ointment made as follows:—
| Araroba in powder | 20 grains. |
| Acetic acid | 10 drops. |
| Benzoated lard | 1 ounce. |
Dr Attfield found the powder to contain from 80 to 84 per cent. of chrysophanic acid, to which substance its remedial powers are doubtless due. It is now the chief source of this acid.
ARA′TION*. In agriculture, ploughing; culture by ploughing; tillage. Lands in a state of aration’ are those under tillage.
