Heat to a temperature of 95 P., two cans of milk. Weigh out 

 125 pounds of ice, crush it, and place it in the brine barrel which has 

 previously been filled about half full of cold water. Add, in salt, to 

 the ice water in the barrel, 5% of the weight of the ice. Thoroughly 

 mix the salt and ice water in the barrel and pump the brine through 

 the cooler, noting its temperature before starting to cool the milk. 



Cool the milk and take the temperature of the mixed milk after 

 cooling. Also take the temperature of the brine as it comes from the 

 cooler. Weigh the ice if any is left, and save it for use in the second 

 part of the experiment. 



Remove all of the brine from the barrel and flush out the barrel 

 and cooler by pumping cold water through them. Repeat the above 

 experiment using 1 5% of salt instead of 5%. Record all temperatures 

 the same as in the first part of the experiment.
