Elements of Myology (Elementorum Myologiae Specimen)

ity. Figure 5 displays them already united, where spaces have been left between the flesh for the sake of greater clarity. F B, G C, are those two straight lines in which the extremities of the flesh are located.

I could have described in the solid of the Order the parallelepiped a solid body bounded by six parallelograms of the flesh and the prisms of the opposing tendons, but since my intention is to accommodate everything to utility rather than to display, I only describe those things whose use will be necessary in the following pages.

Plan of the Order.

Tab. 1. F. 5.

20. From the definition of the order, it is demonstrated that the planes of all motive fibers coincide into the same plane A H, which I call the PLAN OF THE ORDER, where the two opposite tendons constitute the scalene trapezoids A B F E, H G C D, and the flesh constitutes the oblique-angled parallelogram F C, comprehended under the fleshy side F G, and the straight line G C, composed of the tendinous sides of all the flesh, which straight line I likewise call the TENDINOUS SIDE. According to the greater or lesser number of motive fibers composing the order, the parallelogram of the flesh is sometimes a rhombus, sometimes a rhomboid.

Height of the Order.

21. THE HEIGHT OF THE ORDER is the distance between the tendinous sides G C, F B.

Thickness of the Order.

22. THE THICKNESS OF THE ORDER is the distance between the fleshy sides F G, B C, which, from the definition of the order, is evidently equal to the thicknesses of the flesh taken together.

Similar orders.

23. SIMILAR ORDERS are those whose parallelograms are similar to one another.

Homogeneous sides of the orders.

24. When two orders are compared with one another, the SIDES
