cases where ordinary cows’ milk does not digest well. While we 
did not treat any cream with carbon dioxide under pressure, we 
believe that whipped cream could easily be prepared this way with a 
pressure of 150 pounds or less and could be used directly from a 
siphon bottle with convenience. 
PRECAUTIONS IN PREPARATION OF CARBONATED MILK. 
In the preparation of carbonated milk, several precautions are 
necessary, in order to meet with success. In the first place, the 
milk should be drawn so as to be as free as possible from dirt and 
promptly cooled below 45° F. It should be carbonated within a few | 
hours. All the vessels with which the milk comes in contact, from 
milking to bottling, should be carefully sterilized before use. In 
case milk cannot be carbonated quite promptly after drawing, it 
should be thoroughly pasteurized before being charged and bottled.
