VI- An Account of two OhferVations upon the Cata- " 
raEl of the Eye 5 contained in a Letter from 
Signor Antonio Benevoli, MaJler^Surgeon in 
the Hofpital of S- Maria Nuova in Florence, 
. to Valfalva 5 printed in Italian at Flo- 
rence, this prefent lear^ and conununicated to the 
Royal Society, at the Deftre of the Author ^ hy 
Sir Thomas Dereham, F. S'. 
I N this Letter the learned Author informs Signor F'al- 
falva^ that, on the 13th of July in the Year 1710, 
he had couch’d a German Soldier of Cataracts in both 
his Eyes, who immediately after the Operation reco- 
ver’d the Sight of both Eyes, and continued to lee till 
his Death, which happen’d of an Acute Illnels on the 
6th of April in this prelent Year. Upon this. Signor 
' Benevoli took the Eyes out of their Orbits, in order 
to examine whether the Cataradts, which this Soldier 
had been couch’d ol^ confifted of a membranous Pel- 
licle, as Ibme W riters maintain ; or, as others pretend, 
of a preternatural Opacity in the Cryftalline Humour. 
•Proceeding immediately to the DilTedtion of the left 
Eye, upon a careful and very exadt Examination of all 
the Contents of it, he could not find any fuch thing as 
a Pellicle within it, but difcover’d a fmall yellowilh 
Body at the bottom of the Bulb of the Eye, of a lenti- 
.cular Shape, without Adhellon to any of the other 
Parts
