concerning the gold weights,which are either pounds, marks, ounces or angels. . . . We use here another kind of weights which are a sort of beans, the least of which are red spotted with black and called Dambas; twenty-four of them amount to an angel, and each of them is reckoned two stiver weights; the white beans with black spots or those entirely black are heavier and accounted four stiver weights: these they usually call Tacoes, but there are some which weigh half or a whole gilder, but are not esteemed certain weights, but used at pleasure and often become instruments of fraud. Several have believed that the negroes only used wooden weights, but that is a mistake; all of them have cast weights either of copper or tin, which though divided or adjusted in a manner quite different to ours; yet upon reduction agree exactly with them[1]".
I am informed by Mr Quayle Jones, Chief Justice of Sierra Leone, that at the present day, a seed called the Taku, (with a black spot) is employed by the natives of the Gold Coast for weighing gold. He also tells me that small quantities of gold are measured by a quill in ordinary dealings in the market[2]. I learn from another private source that 6 Takus = 1 ackie (20 ackies = 1 ounce). From Bosnian's equating the bean with the red spot to 2 stiver-weights, we can deduce its weight as 2 grs. troy; this result combined with the colour of the bean would make us a à priori conclude that the Damba was the Abrus precatorius, so familiar to us already under its Hindu name of ratti.
Here we have a primitive people with a weight system of their own based on the Damba and Taku, just as the Hindu is based on the ratti, and here too we have another proof that the first of all articles to be weighed is gold. From Bosman we also learn that gold in small quantities was not always weighed, for he says of the inferior gold which was mixed with

- ↑ Although I have made many enquiries and Dr Thiselton Dyer of Kew has taken much trouble in the matter, I am unable to give the reader the botanical names of the Taku and Damba. Dr Dyer thinks the Damba is our old friend the Abrus precatorius, the Indian ratti, confirming the opinion I had previously formed from its weight. These seeds are commonly known as crabs' eyes.
