It would be possible, by very careful dissection, to split the heart down the middle of a partition, or so-called 'septum', which exists in it, and to divide it into the two portions which you see here represented; in which case we should have a left heart and a right heart, quite distinct from one another.
It is of great importance you should clearly understand these teachings of Galen, because, as I said just now, they sum up all that anybody knew until the revival of learning; and they come to this that the blood having passed from the stomach and intestines through the liver, and having entered the great veins, was by them distributed to every part of the body; that part of the blood, thus distributed, entered the arterial system by the 'anastomoses', as Galen called them, in the lungs; that a very small portion of it entered the arteries by the 'anastomoses' in the body generally; but that the greater part of it passed through the septum of the heart, and so entered the left side and mingled with the pneumatised blood, which had been subjected to the air in the lungs, and was then distributed by the arteries, and eventually mixed with the currents of blood, coming the other way, through the veins.
The animal of the recent Turritella communis partitions off in like manner as it advances in age a part of its spire, forming a shelly septum. Bellerophon costatus, Sowerby. The genus is not met with in strata of later date.
This is a very common cause of catarrh, and requires, for its cure, a slight operation, a cutting away of the bulging or projecting part of the septum. The rims of the openings of the nose, known as the wings, have little muscles fastened to them which pull them upward and backward, thus widening the air openings or, as we say, dilating the nostrils.
A big nose, aquiline, and broad at the base, with great thoroughbred nostrils and the "septum" between them thin and deeply depressed; and there was a turn down at the corners of the mouth, and a breadth of lower lip, that reminded one of his Verona griffin, half eagle, half lion; Scotch in original type, and suggesting a side to his character not all milk and roses.
Their color is a dirty black; they have low foreheads and flat noses, artificially enlarged by sticks run through the septum, and file their teeth down to a point.
The outline of the body is more nearly rectangular than in other Flat-fishes from the obtuseness of the snout and caudal end, and the somewhat uniform breadth of the body. The surface is rough from the presence of long slender spines on the scales. There is a large perforation in the septum between the gill cavities, but this occurs also in Arnoglossus megastoma, which is placed in another genus.
The frozen ears and cheeks healed in due time, and the gangrenous parts of the nose separated and soon healed, with the loss of the tip and parts of the alae, leaving the septum somewhat exposed.
The Bashinje, in whose country we now are, seem to possess more of the low negro character and physiognomy than either the Balonda or Basongo; their color is generally dirty black, foreheads low and compressed, noses flat and much expanded laterally, though this is partly owing to the alae spreading over the cheeks, by the custom of inserting bits of sticks or reeds in the septum; their teeth are deformed by being filed to points; their lips are large.
They vary in length from .04 to .06, and even to .08 of an inch in length; and in diameter from .006 to .008 of an inch. Near one extremity of the cylindrical part, a green septum, formed of granular matter, and thickest in the middle, may generally be seen.
