He likewife takes notice, that there Was a Skele- 
ton in the Phyfick-School at Alexandria, which 
he thought would amply compenfate the Trouble of 
anyone to go on Purpofe to ftudy. 
The Figure reprefenting Galen contemplating the 
Skeleton, is taken from a Philofopher of Salvator 
Rofa. 
At the Bottom of the Title-Page he has given a 
Print of a Camera Obfcura, which he mentions in his 
Preface to have contriv’d and drawn all his Bones by, 
and without which Affiftance (notwithftanding he 
employ’d the greateft Artiils in their way) he found it 
impoffible to give a true and perfect Reprefentation 
of them, there being fo much Difficulty to exprefs 
the Outlines of Bones in their different Attitudes. 
This occafion’d my looking into Kef alius ' sBook of 
Anatomy more carefully than I had done before, whofe 
Figures have hitherto been efteem’d the moft beauti- 
ful of their Kind, and are perform’d in fo exquifite 
a Tafte, that they haveufually been taken for Titi- 
an’s, and always confider’d as a Study for Painters. 
Yet whoever will give himfelf the Trouble to 
meafure his Bones with real ones, will find many 
egregious Errors, which would- take up too much 
room here to particularize ; but upon the whole I 
find there is no kind of Proportion kept, and that 
his Bones in general are between one Third and 
Fourth Parts too (hort for their Breadth : And tho’ 
his three Skeletons have been fo remarkably famous, 
that feveral Anatomical Writers have copied after 
them, yet when carefully examined, it will be very 
eafy to difcover many Imperfections in them, though, 
all together, they Itrike the Eye wonderfully.
