The fcaksoh^t Belly were joy n^d to each other by di- 
ttmCk mufcles; the loyjtvTendonoitzch mufcle being in- 
ferted into the upper edge of the following yr^/<?> and 
t\\t OihtrTendon of the fame Mufcle inferted about the 
middle of the foregoing/^^&. Thefe Mufcles were raore * 
fleflby towards the middle of the/r^/(?:; and then 'n% fibres 
did run obliquely afcending. To each fcale was appropri- 
ated a litb 3 whofe point did joyn with the extream of 
itjwhichmuft much advantage the ufeiVis!^2/r^feems to de- 
fign them for, by ftrengthening them to perform their 
reptile motions*^ for the fcales are as fo many feet> which being 
free, and open downwards, they thereby take hold of the 
ground, and fo contraQ: their body forwards^* and then 
(hoar out again , and fb perform their ^tzo/'/^?;?. Whence tis 
obfervedby ^ Nierembergius ^ that on l^pcks their motion 
is much quicker, than on the Earthy or Plains ; which he 
needed not to make a wonder of , fince here they have 
the firmer footing. But in foft ground, tho their belly be 
flar:»yet they can contrad it to an Ellypfis or an cicute angky 
that fo they may take the deeper hold, as I have obfer- 
vedina^^^r. 
Since they muft be always grovelling on the ^r^?2<j;?/^.y 
'cis a great provifion of Nature infurnifliing them with 
this coat of armor for their defence ; which is fo curioufly 
contriv^d,that tho it covers the whole, yet by its frequent 
joyntings it admits of all motions. And for this too, the ver- 
tebrce of the ^///^ feem admirably contrived^ there being 
a round ball in the lower part of the upper z^^r^^^m , which 
enters a focket of the upper part of the lower vertebra i as 
the round head of the T/&^^/? bone does xht acetabulum 
of the OS IJchii, by which means it can turn it felf any way. 
Having placed it on its bacJ^> we bpenedfic , and ob- 
ferved that the Tendons of the abdominal mufcles mzde 
Unea alba in the midft of the/^^fej-of the Belly ^ where like- 
wife did run a large blood VeffeU arifing from the Vena *F/^. jc rr. 
f^z/^>towards the lower part of the Liver.But not to be too 
nice
