The milk, having been Eod into the bag until the tin is half

bag of sand weighing about 10 pounds may then be put on top of 
the piece of wood for another 12 hours. Quantities of discoloured 
water will be seen to flow from the perforations in the sides and 
bottom of the tin during this process, and on touching the top of 
the bag it will be found to offer some resistance to pressure.
