We now reach the confluence of the Nkonio or north-eastern, with the Mbokwe, or eastern branch, which anastomose to form the Gaboon; the latter, being apparently the larger of the two, preserves the title Mpolo. Both still require exploration; my friend M. Braouezzec, Lieutenant de Vaisseau, who made charts of the lower bed, utterly failed to make the sources; and the Rev. Mr.
Hewson, who observed, "That the lacteals near the root of the mesentery anastomose, so as to form a net-work, from which several large branches go into some considerable lymphatics lying near the spine; and which can be traced almost to the anus, and particularly to the kidneys." Philos. Trans. v. 59. p. 199 Enquiries, p. 74.
Mary, rose a whitewashed building from a dwarf red cliff. This 'silk-cotton-tree' differs greatly in shape from its congener in Eastern Africa. The bole bears sharp, broad-based thorns; the wings or flying buttresses are larger; several trunks rarely anastomose; the branches seldom stand out horizontally, nor are the leaves disposed in distinct festoons.
But, on the other hand, the elements that compose it are probably discontinuous; at any rate, even supposing they anastomose, they exhibit a functional discontinuity, for each of them ends in a kind of cross-road where probably the nervous current may choose its course.
The diaphysis is also nourished by numerous blood vessels from the periosteum, which penetrate the cortex through the Haversian canals and anastomose with those derived from the nutrient artery. The epiphyses are nourished by a separate system of blood vessels, derived from the arteries which supply the adjacent joint. The veins of the marrow are of large calibre and are devoid of valves.
