nefg to an extraordinary fact, to me totally new, and whichis. 
in my opinion, cannot eafily be accounted. for. One day 
when fome people in this neighbourhood were preparing to 
churn butter, they were aftonithed to find all the cream of a 
fine Pruffian-blue colour. The cafeous part was only blaeith; 
Every attempt to difcover the caufe of this extraordinary co- 
Your was fruitlefs, though the cream exhibited the fame ap- 
pearance for nearly three months. It cannot be afcribed to 
the veffels in which the milk was generally preferved, ‘as 
they were always kept perfeétly clean, and covered with fir- 
boards. The cows were in exceeding good health, and, fed 
on meadows on which they had grazed for feveral years. 
This milk was ufed as food without any hurt enfuing, and 
it betrayed no particular tafte; but the cream. and cafeous 
parts were thrown,away, as they infpired fome dread.» The 
ercam gradually changed its colour; but this could.not be 
aferibed to the means employed during the continuance of 
the phenomenon, means indeed fo ridiculous that I do not 
think it worth while to detail them. 
«In the Ephemerides of the Curious of Nature, Dee. 2d, 
1688, we find inftances of milk being coloured green, black, 
red, and yellowy; but Tam acquainted with no obfervation 
fimilar to that above mentioned.”
