I had alfo a little piece of a Sea Shell, which we all 
a Horn, upon which, in 4 feveral places, there grew little 
Particles ot red CoraL 
This fnuail piece of a Sea Horn was grown over with a 
petrifyed Matter, in which Matter there was a great many 
fmailHoles^ and obferving likewife feveral fmall long 
Animalctila that were alfo furroundcd with a Petrifyed 
Matter, and vvhofe Figures exa(3:ly agreed with thofe little 
Holes ^ I began to confider whether, or no thefe Animal- 
cula might not have belonged formerly to thofe Sea Horns 
or Shells,

Now, That red Coral fhould grow in the bottom of

produc'd by fuch a Coagulation of Parts. 
As for the Particles of the faid Coral, they are not 
compofed of Branches, but they lay by, and upon one 
-.another like the great Sands that were joyned to each 
other 5 but when one looks upon them through the Mi- 
crofcope, one can eafily perceive that the parts of which 
they are compofed were firmly united to each other, and 
. that the Ground to which they were fixed was more 
broad than high. 
I took this forementioned Scollop and Sea Horn, which 
was overfpread with Coral, out of a great Spunge, but
