the Royal Society, concerning the Stones 
mentioned in the preceding Article, By Mr,

My Lord, 
Read Feb. 5* A S your Lordfhip was pleafed to in- 
' JLjl. form me, that the council had 
thought fit to order Mr. Byam’s account of the foflil 
fi£h, found in Antigua, to be printed, which curious 
fpecimen my worthy and moft efteemed friend Wil-

my colledtion ; I have made a drawing of it, that a 
print, the befl; illuftration of the account, may ac- 
company it, and have taken the liberty add a Ihort 
defcription of the colours, and fome other particu- 
lars, which will not be apparent in the print. 
The impreflion of this fifh is in a chalky kind of 
fione, of a pale ochrey colour ; fome parts, when 
fcraped, are white, and all the imprefiion is of a yel- 
lowifii brown, nearly the colour of brown ochre. 
The impreffions of the bones and fins are very per- 
fed; ; and the cavity, that contained the back-bone, 
extremely fharp and delicate. When I firft faw it, 
two or three of the vertebrse were in it. All tho ca-

tain them, and ’tis probable, that moft, if not all of 
them, were in the ftone, when it was firft fplit.

which come down from the head, which parts were
