the buttocks, 41, Quadrigeminus primus, it arifes from the lower. part of the os fa- 
crum, and is placed. upon the articulation of the thigh, in the hinder part thereof. 
12, Quadrigeminus fecundus, arifes from the tuberofity of the huckle-bone, and covers 
the articulation of the thigh, as aforefaid. 1 3. Quadrigeminus tertius, is contiguous 
to the former, and arifes from the fame part: thefe three lait are inferted i into the ca- 
vity of the great trochanter. 14, Quadrigeminorum quartus, it is broader and more 
flefhy than the other three, being diftant from the third of the quadrigemini two 
fingers breadth; it fprings from the inner fide of the apophylis of’ the ifchium or 
huckle-bone, and is inferted into the external part of the greatttochanter, 15. Obiu- 
rator externus takes up the wide hole, between the os pubis and os ifchii, and arifes 
_ from the outward circle of the os pubis, is circumdyucted through the neck of the: 
thigh, and carried into the cavity of the great trochanter, under the fourth quadrige-* 
minal mufcle. 16. Obturator internus, rifes from the inward circle of the os pubis, 
and by atripatite tendon is inferted into the cavity of the great trochanter. : 
To the legs belongeleven mufcles, viz. 1. Biceps, having twoheads; thefirft fprings 
from the joining of the os pubis, the fecond from the outward part of the thigh ; 
both of them. are inferted with one tendon into the hinder or inward part of the leg. 
2. Semimembranofus, arifes from the {welling in the ifchium, and is inferted into the’ 
inner-fide of the leg backwards... 3, Seminervofus, has the fame original and infertion” 
with the former, only inthe hinder part is carried:a little forwards obliquely, before. 
it terminates at the infide of the leg. 6. Gracilis, and gracilis pofticus, rifes from that 
line where the hip-bone and fhare-bones join together, and, defcending along the. 
infide of the thigh, i is inferted into the inner part of the leg. 5. Reus gracilis {prings. 
with an acute tendon out of the outward and lower {pine of the os ilium, is carried 
along the thigh, and terminates in the fore-part of the leg. 6. Vaftus externus borders 
upon the rectus gracilis, and arifes out of the great trochanter, and is inferted into the 
leg, a little below the patella onthe outfide. 7. Vaftus: interns, borders as the former 
on the rectus gracilis, and arifes out of the root of the fimal] trochanter, and falls into 
the, inner fide of the leg, a little below the patella. - 8. Crureus, arifes out of thethigh> 
bone, between the twotrochanters, and, cleaving to the the thigh, produces its tendon. - 
over the epigonatis, unto the fore-part of theleg; the four lait. mufcles are inferted 
all i into one tendon, which terminate in the beginning of the leg. 9. Mujculus longits,” 
itis nearly the longeft of all the mufcles ; arifes from the former {pine of the os” ‘thi! 
and defcends obliquely into the inner and fore part of the leg. 10. Popliteus, it arifes> 
from the lower and exterior tubercle of the thigh, and is inferted four-fqui re into? 
- the inner and upper part of the Teg, obliquely. it. Membranofus fafcia: cara 
from the fpine of the os ilii, runs obliquely into the outward part of ee -~ ind, 
| with a broad and long tendon, invefts almoft all the mufcles of the thigh.”
