    'w <■ tf THE next Range of Fibres in the Heart are likewife RhomboidaleSy and run direftly contrary to the laft, namely> [1 from the right fide to the left, and winding about both Ventricles, -] mount again fpirally to their Infertion in the Tendons of the J Balls. This Plan, with the laft, being both oblique Prifms, I form a fourth Species, call’d Mufculi T>ecujfati. [See Fig. 7. Dccun~atI. 3 Plate 2.] j| UNDER the ftraight Fibres there are a few which almoft run in right Lines ifTuing from the oppofite fides of the Pulmo¬ nary Artery, and are inferted into the fecond Tendon of the Aorta on one fide, and into the Mouth of the right Ventricle on the other. Thefe two Plans of Fibres are reducible to the fifth Species of Mufcles, call’d Mufculi Tenniformes. [See Fig. 1. Plate 2.3 Mufculi F niformes. FROM the firft Tendon of the Aorta, there are feveral other Fibres defcending half-way downwards obliquely to the Apex, making a few fpiral Circumvolutions round the right Ventricle, al'cend afterwards either to be inferted into the Tendon of the Pulmonary Artery, or lofe themlelves in the flefhy Pillars, or TapilU in the inlide of the right Ventricle. 1 )' ti | FRO M what I have already explain’d, it is evident, that . all the Fibres, which compole the Heart, iffuing from the Tendons in its Balls, like fo many Rays from a common Center, ij form the fixth Species, call’d Mufculi Radiojt. And, again, Mufculi} ’tisnolefs evident, that the Tendons which give Rile to thefedl0h' !] Fibres, and where moftly they are inferted, being only lb many Ringlets of a finer fort of Fibres very firmly and clolely com- I padded, form a feventh Species of Muicles, call’d Sphrncteres sphin£tc| Circulares; which will appear more plain in the Sequel of thefe Leaures. [See Fig. i. Plate 2.] * 'ij BUT befidesthefe Tendons, there are likewileSemicircular Fibres which furround the two Ventricles, which are of extraor¬ dinary
