So far in all their various forms, whether straight, as the Orthoceras, or curved, or close- coiled as in the nautilus, the septum, or partition dividing the chambers, met the inner shell along a simple line, like that of the rim of a saucer.
The septum of the nose appears to have been pierced, and the horizontal depression across the upper lip may indicate the former presence of a suspended ornament. Perhaps the most unique and striking feature is the pattern of incised lines that covers the greater part of the face.
In this collection there was an adult heart in which the foremen ovale remained open until the age of thirty-seven; there were but two pulmonary valves; there was another heart showing a large patent foramen ovale from a man of forty-six; and there was a septum ventriculorum of an adult heart from a woman of sixty-three, who died of carcinoma of the breast, in which the foremen ovale was still open and would admit the fore-finger.
The question of the transmission of blood through the thick septum and the transference of air and blood from the lungs to the heart were secrets which he was desirous of searching out by means of experiment. Harvey: Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus, Francofurti, 1628. One or two special points in the work may be referred to as illustrating his method.
This CENOGENETIC "primary cardiac septum" presently disappears, and has no relation to the subsequent permanent partition between the halves of the heart, which, as a heritage from the reptiles, has a great PALINGENETIC importance.
The animal appears to have retreated at different periods of its growth from the internal cavity previously formed, and to have closed all communication with it by a septum. The number of chambers is irregular, and they are generally wanting in the innermost whorl.
This small fraction of venous blood, charged still with the natural spirits derived from the liver, passed through minute channels in the septum between the ventricles and entered the left chamber. In the arterial system it also ebbed and flowed, and might be seen and felt to pulsate there.
Anatomical investigation shows that the bony interorbital septum composed principally of the frontal bones, which in symmetrical fish passes between the eyes, is still between the eyes in the Flat-fish, but has been bent round through an angle of 90 degrees on the upper side, while in the lower side a new bony connexion has been formed on the outer side of the eye which has moved from the lower side.
Immediate steps were taken in consequence to prevent the recurrence of such collisions when thoughtless curiosity on one side is apt to be promptly resented on the other if numerically superior in force... The men had large cicatrices on the shoulders and across the breast and belly, the septum of the nose was perforated, and none of the teeth had been removed.
Vesalius accepted Galen's view that there is some communication between the venous and arterial systems through pores in the septum of the ventricles, though he had his doubts, and in the second edition of his book says that inspite of the authority of the Prince of Physicians he cannot see how the smallest quantity of blood could be transmitted through so dense a muscular septum.
