1036. The blood seems to move in similar spiraling gyres
When the red blood cells are tender, soft, solute, fluid, it seems that they are then able to move in similar spiral paths to that of spirits introduced into a society, and likewise in fourfold measures [1031]. The blood cells seem in this case to flow, or at least to endeavor to flow, in similar gyres, as is evident from their shape. And anyone who does not, or cannot, move in the same gyres, is banished from the company, or from the circle, and is agitated as spoken of earlier [1015-1016, 1033-1035]; for the gyre is not a simple gyre, but a whirling circle.
1036. THAT THE BLOOD SEEMS TO PERFORM SIMILAR GYRES
When the red blood, or its globules, is tender, soft, soluble, and fluid, it seems to be able to perform gyres similar to those of spirits inaugurated into their society, and this with four-fold terminations. The blood globule seems to flow, or at least endeavors to flow, into such gyres, as is evident from its form. That which does not endeavor to flow into these gyres, or cannot, is banished from the community, thus from the circulation, and is vexed, as was said before [nos. 1015-16; 1033-35]; for a gyre is not a simple gyre, but revolves.
1036. Quod sanguis videatur similes gyros agere
Sanguis rubeus, seu globulus ejus, dum tener, mollis, solubilis, fluidus, tunc videtur similes gyros posse agere, sicut spiritus in societatem inaugurati, et quidem cum terminis quadruplicatis, in similes gyros sanguineus globulus videtur tunc fluere, ad minimum conari fluere, quod ex forma ejus patet; quique non in similes gyros conatur fluere, vel fluere potest, is exterminatur a consortio, sic a circulo, et vexatur, ut prius dictum [1015-1016, 1033-1035], nam gyrus non est simplex gyrus, sed volubilis circulus 1
