Aimes,as well diftinguifliablc as appears in this F/^/zr^ 5 w hich 
repiefents it juft as it was given mc, I durfl not yet attempt to 
feparate the Flefh from thefe little BoneSjOr rather from thefe 
fmall Cartilages, which in tfme become Bones ^ all thefe parts 
being yet too tender to make an accurate difleftion of them* 
In ^/f^^r^VlL is delineated a child, which is already furuifhed 
with all its CartilageSj though it had been conceived but three 
weeks. It being fallen into my hands, I attempted to fever 
the ^kin and the flefli from the Cartilages-, holding the place 
of the Boncs^ and I fucceeded well enough in ir^ and keep OiH 
by me the Sceleion thereof, truly reprefented \n\h\hFigure. 
The Head 5 wherein the Brain is to lodge and all mans 
wifdome, is nothing but a fimple membrane inflated with wind 
or Spirits. The Armes are diftinft from the Body, and ihe 
Hands have now their fingers perfectly difiind:. One 
may eafily count in this contexture of Cartilages, how many 
Ribbs there will be. Andlaftlythe diftindion of the Toes 
of the Feet is as pcrceptible^as that of the fingers of theHands. 
But we muft add withall 3 that all thefe parts are no longer 
then hairsj and confequently a great dexterity aud nicenels is 
to be ufcd for difplaying thctn* 
Figure VHI.reprefents a/<e^»/ of a moneth,havingnowthe 
whole humane ihapejand the Bones thereof firm enough in ma- 
ny places to fupportthe parts. Behold the Figure welLwhich 
reprefents this litle Engin in its natural fize. It already in a 
manner fuftains it felf. The two Jaw-bones appear ; the cla- 
vicles are formed 5 and all the Ribbs are very diftirdt, tx« 
cept the firft and laft 5 which are not wont to have5cveu in the 
Second momih.iht confiftence of Bones. One may fee in the 
Armes the Joynts of the Shoulder-bones and of the Elbowsj as 
alfo the Thighs and both the Leggs, together with their 
bones5 called Focils ^ which I had notobferved, when I wrote 
my treatife of the Generation of the Bones. All what you fee of 
white in this eight figure, hath at this time the quality of bones. 
Where I have a fair occafion to enlarge and to difcufs that great 
queflion, whence proceeds the hardnefs in Bones ? And I could 
not give a better,nor a more curious reaibn for it, than by 
alledgiDgthe dodlrinej that fcrveth for a ground toallChy^
