56 A DAIRY LABORATORY GUIDE 



4. Test the whole milk for acid, using 18 grams. 

 Use both n/io and alkali tablet solution. 

 Test the skimmed milk for acid, with the n/io 

 solution. Use only 5 cc. of the milk. Do this 

 twice, so that one result will be a check on 

 the other. Again test the skimmed milk, 

 using a 50-cc. sample. Do this twice. See 

 if you get the more uniform results with the 

 large sample.
