Details

During the period 1652--1900, wood from both the indiginous Ocotea bullata (`Stinkwood') and the imported Ocotea perosa (`Imbuia') were used to make Old-Cape furniture in South Africa. The data set contains mean measurements made on such wood, together with a third species, Ocotea kenyensis. Twenty samples of Ocotea bullata (Obul), 10 samples of Ocotea perosa (Opor) and 7 samples of Ocotea kenyensis (Oken) were inspected microscopically, with six variables measured on each sample 50 times over. The data are the mean measurements over the 50 repetitions.
