DIVI-DIVI is the commercial name for the curved pod of a leguminous shrub, Cæsalpinia coriaria, which is sometimes imported from Carthage. Its tannin differs materially from that of nutgalls. The quantity of mucilage which it contains precludes it from the use of dyers; but, as it furnishes nearly 50 per cent. of tannin, it is largely used by curriers. It is imported into Liverpool from Rio de la Hacha, Maracaibo, and Savanila. 400 tons of the seed pods and bark of the Algaroba, or Locust-tree (Prosopis pallida) were imported in 1849 into Liverpool from Valparaiso, as a substitute for divi-divi in tanning. 3,200 lbs. of divi-divi were exported from the port of Augostara, in 1846.
Specimens of divi-divi which had been raised at Calcutta were shown in the Indian department of the Great Exhibition.
Dr. Hamilton states that, according to some admirably conducted experiments of Mr. Rootsey, of Bristol, undertaken at his request, the pods of divi-divi contain above 50 per cent. of tannin. It appears also, from trials made, that one part of divi-divi is sufficient for tanning as much leather as four parts of bark, and the process occupies but one-third of the time.
The average produce of pods from a full-grown tree has been estimated at 100 lbs. weight, one-fourth of which consists of seeds or refuse, leaving about 75 lbs. of marketable matter.
