ly be reputed a publick lafsjand a detriment to the very Fa- 
culty of Phyfick^) fa w but a very few dayes before his deceafe 
this Book of hisfinlflied in thePrefs, to which , if Heaven had 
thought good to have- fpared him longer amongft us, he would 
doubtlefs have added many other Philofophical and ufeful Pieces^ 
for the improvement of Knowledge and the Art of Phyfick^ But 
fincethat is denied us, v^e muft content our felves with what he

In the Anatomical part, he doth with admirable curiofity and in- 
comparable accuracy defcribe and difcourfe upon the wonderful 
Fabriqueof the Lungs, which^with tlie Excellent Malpighm.ht 
makes to be, in their whole fubftance, fiftulous, and compofed of
