127. The purple dye from the murex

Murex is engendered in every sea, more than in island places. It is a little shell, which has in it a place for blood, and the blood is a reddish purple: from this the purple dye is made. It is collected like this. Take the murex and collect the blood with the flesh and take some brine from the sea and put them together in a pot and leave it.
