die World till about five Years after Dr. ‘Douglass 
Book came out ; and even when they were found, 
they had no Explanation, till Lancifius firft explain'd 
them in the Year 17x2. who, notwithftanding, never 
took any notice of the Coccygreus Mufcle in his Ex- 
planations; although we may affirm Morgagni af- 
lifted in them : For Lancifius , after he had been 
order'd by the Pope to pubiifh his Explanations* 
wrote Letters to one Fantonus, and to Morgagni, 
both Phyficians and Profeflors of Anatomy, fetting 
forth the Difficulty of the Task, and requiring their 
Opinions and Affiftance in altering whatever they 
might fee amifs in what he had done. He received 
Anfwers from both ; and in that of Morgagni a par 
ticular Recapitulation offome Part or other of the Fi- 
gure of every Table, except that of the xxxvi. Plate, 
which alone contains this Mufcle in Queftion. But, 
afterwards he tells us, in his Adverfiaria , (which 
were printed as late as the Year 17 19.) that he dif- 
cover'd it himfelf, and calls it Muf cuius Coccygis 
Levator . See the End of his 45 th Animadverjion ; 
for before this, neither Lancifius , Fantonus , nor 
Morgagni, took notice of it : Whereas Dr. Douglas not 
only difeover’d the Mufcle, and demonftrated it to the 
Students who attended his Ledures, but alfo invented 
the Name for it, fo many Years as I have mentioned 
before Euftachiuss Plates were found. It would 
have been an ungenerous Omiffion, to have neglected 
fetting this Part of anatomical Hiftory right, fince 
I was fo happy to be well acquainted with his great 
Abilities in this and other Branches of Learning in 
his Life- time ; and particularly, fince I find a foreign 
Author, of fo much Credit as Santorini , very much 
miftaken
