of commerce, and whether in that way the idea was promulgated that it was produced in the laud and districts from which it was shipped, by way of the lied Sea to Europe. In answer to a question Mr. Haubiiry further mentioned that the common name in India of Cinnamon — ' Dar-Chiui' — seemed to indicate that it was originally obtained from China (Cassia), and not from Ceylon. Cinnamon and Cassia were anciently hardly dis- tinguished. Cinnamon was indigenous to Ceylon, but the form which
yielded the bark was a cultivated one. Captain Elton, "The Limpopo
Expedition." In the discussion it was stated that some interesting in- ferences as to the former physical features of this country had been de- duced by Mr. Chapman from the mode of growth of the 15aobab. It occurs in groves on little elevations in wide plauis, which were once possi- bly lakes. The trees of each group are of about the saine age, the oldest being highest up the country. It is possible that the seeds of the Baobab only germinate just a little above the level of the water. As the country became drained, each elevation, on its emergence, would be stocked with the Baobab by fruits floating down from the older and higher groves.

else done by Dr. Joseph Hooker, this investigation had been carefully and thoroughly carried out, and a great desideratum of botanical knowledge had been obtained. The absence of Primroses, Gentians, and Anemones was most remarkable. The observation on the exhausted condition of the forests was also noteworthy.
