Brain Stones. 
This is frequently much bigger than ones Head, roundifh at top, or a He- 
mifphere, having many undulated Furrows on its top, imitating fomewhar 
the gyri or anfracius of a Man’s Brain, from whence they are commonly call’d 
Brain Stones; thefe Furrows have Lines go from their middle to cach fide, 
they are White, and make as it were high Banks in the Stoae, which are 
fometimes waved like the Sea; from whence the Name Aftroites undulatus. 
There is {ome variety in this as to the bignefS of the Su/ci. 
They grow in all the Seas about this Iland, and vary very much as to 
bigne(S and manner of growth, having very often within them {mall White 
Shell-Fifh. ‘This is mentioned to be found by my good Friend Dr. Charles 
Leigh, in his Natural Hiftory of Lancafbire, Gc. Tab. 2. Fig. 1.

This is for Colour, Subftance, éc. exactly the fame with the former, only 
inftead of undulated Sw/ci or Furrows, are only {mall holes, pipes, or {pots, 
in whofe cavities are Strie, or partitions coming from the fame Center to 
the Circumference. 
This is as frequent in all thefe Seas as the former, and is found in Eu- 
rope in feveral places at Land, petrified and not petrificd as Sea-Shells. 
Mr. Charlton gave me apiece of it capable of polifh, petrified and tranfpa- 
rent like an Agat, only the Strie were White. Thefe Stones are moft cer- 
tainly bred from a Seed ; for in the places where they are moft to be found 
in {hallow Sea-water, Ihave feen what we may call their Seed or Spawn very 
frequently, viz. a mucilaginous, cryftalline, clear Body, of the fame fhape, 
and with the fame {pots on their Surface, only no Strie going from the 
Center of the holes, which when taken up in the heat, does out of the 
Water corrugate and contract its felf into narrower dimenfions, turn Opaque 
and of an Ath, or pale Yellow Colour, in which notwithftanding may 
plainly be feen the rudiments of the Stone. : 
Thefe Affroites Stones are taken up from the bottom of the Sea by 
Divers, and breught on Shore not only to burn with Timber to make Lime; 
but likewife to build, and that not only ordinary Houfes, but Forts to refift 
the battery of Cannon.
