Bottle for Carrying the Sample. — We prefer a two-ounce, wide 

 mouthed bottle, made of strong glass and provided with a cork 

 stopper. A case should be provided for these bottle with pockets 

 to prevent them from rattling around, and a closely fitting cover to 

 protect them from cold weather in winter. Each bottle should be 

 given the number of the patron for whom it is to be used. 



SAMPLING FOR THE TEST. 



Manipulation. — After the cream has been turned into the 

 weighing pail, the sample is taken by letting the sampling tube, 

 with the lower end open, slowly down to the bottom of the pail. 

 The lower opening is then closed, the tube taken out, allowed to 

 drain a moment and the contents tuu into the bottle marked with 

 the patron's number. It is very essential that this tube be let 

 down slowly and that the lower end be open, so it will fill as 

 it goes down, taking a section of the cream through the whole 

 column and insuring a correct sample. If the tube is let down 

 quickly, or with the lower end closed, and then allowed to fill from
