thofe in Men; behfg porter, by reafon the OlTa Ilium m Jpes are mnchfirai- 

 ter than in Man. The Ghit£m medius was alfo longer than that in Man. 

 The P/tf^ ^ii?i;g«/^ vvas alfo longer ; \v\iv:^ Sylvius (from it's Figure I 

 luppofe) calls Lumhark Bleep mApes. The Pfoas parvus was alfo lon- 

 ger and larger, than in Man. Befides this, the Parifians tell us of two 

 other little Mufdes in Monkeys^ which have the fame Origin as the Pfoas 5 

 and were inferred into the upper and inward part of the Os Pubis. The 

 Iliacus Internus was long, conformable to the Figure of the Os Ilium oi 

 this Animal-^ (FideFig. 5. 28. 28.J The Pe(^Ti«e/iy was not very difdnft. 

 The Triceps (Fig. 4. 37. ) had no Tendinous Termination at the lower 

 Appendix of the Thigh-bone internally. Jacobus Sylvius fays in Apes, 

 Tricipitfs pars longijji/na a Tubere in Condyhtm : altera portio infignis^ a Tu- 

 bere etiam nata, pojiico cruri propi toil affixa, ad ufque Cavitatem ittter duos 

 condylos ntediam : tertia minima (^ brevijjima ojjis pubis in medium © po- 

 pcnmOs Cruris. The Pyriformis (Fig. 4. 35.) was like the Humane ^ 

 nor did it appear lefs in proportion, as the Parifians reprefent it, in 

 Monkeys, who fay, This Mufcle, injie ad of taking it's rife fiom the loiver 

 and external part of the Os Sacrum, it proceeded from the Ifchium near 

 the Cavitas Cotyloides, The Marfupialis had its Marfupium much broa- 

 der than in Men. The ^ladratus Femoris was lefs than in Man. The 

 Obturator extrorfum was much larger. 



The Common Mufdes of the Thigh and Leg^ agreed in their Situation 

 and Number, with thofe of Me«. The Membranofus (Fig. 5. 41.) had 

 not fo ftrong a Tendon to cover the Mufdes of the Thighs and Tibia, as 

 in Man. The Sartorius ( Fig. 3. 42.) agreed with the Humane. The 

 Gracilis (Fig. 3. 48. ) was thicker and larger near it's Origin. The Se- 

 minervofus ( Fig. 4. 40. ) and Semimembranofus , differ'd not from the 

 Humane. The Biceps (Fig. 4. 41. ) had it's fecond beginning , fome- 

 what lower, than in Men : The Pari/ans tell us, The Biceps in Monkeys 

 had not a double Origin as in Man, hit proceeded i»tire, from the Knob of 

 the Ifchium , and was inferted to the upper part of the Perona. This Jingle 

 Head was in requital very thick and firong. The ReBus had a double or- 

 der of Fibres, as in Man. The Popliteus, I muft confefs efcap't my no- 

 tice. Sylvius tells us, in Apes, it agrees with Men. The reft: of the Muf- 

 des of this part, which we eftieem Proper to the Tibia,and arife from the 

 Os Femoris, were much lefs than the Humane, as the Vafius Internus , 

 (Fig. 3. 44.) Crureus, &nd Vajius externus. 



The Mufcles of the T<?r/Ay or F<?of, agreed in Number and Situation 

 with the Humane ; but varied in their Figure. The Gajlerocnemius ex- 

 ternrn ( Fig. 4. 43. ) had not fo large a Belly, nor were it's Fibres fo va- 

 rioudy difpofed ^ but it continued flefliy much lower, than in Man. 

 Sylvius tells US in Apes, Capita GemeUorum ( meaning this Mufde _) Offa 

 Sefamoidea habent , frmantia in Condylis Crus cum Tibia. The Plantaris 

 differ'd not from that in Man. The Gafierocnemim internus, or foleus,
