of whofe Ureters was grown up ; a Prefent

Dear Sir , 
Read Dec - HAVE now an Opportunity of fending 
744 JL y°u, inclofed, the Cafe of one Han- 
nah Hitchcock ; and a little Box, containing the Stones 
taken out of her Kidneys. 
In the Box alfo I have fent one of the mod 
remarkable Stalactites I ever faw. Perhaps it may 
be a Curiofity even t o you. - — It was found in a 
Cavern, that was difeovered amidd the vad Marble 
Rocks at Cat -down near Plymouth. It hung per- 
pendicularly from the Top of the rocky Cavern, and 
was a cylindrical Tube of twenty Inches long at lead ; 
but was unluckily broke into feveral Pieces in Bring- 
ing to me. This I have fent was by much the longed 
of them; but Mr. Long (the Mader of the Quarries) 
allured me the Whole was above twenty Inches long, 
and quite cylindrical, and quite hollow. — — 1 went 
to the Cave the next Day, and found five or fix of 
fuchKind of Tubes, but none above two Inches long. — 
They all fprang from a broad, hollow, protuberating 
Bads, in fome fort as a Nipple arifes from the Bread.
