Instead of weighing 4.5 grams into the test bottle, a 4.3 ex. 

 pipette may be used. After emptying the pipette into the bottle it 



should be rinsed twice, and the rins- 

 ings discharged into the test bottle. 

 For making numerous tests 

 from the same sample it is advis- 

 able to dilute the evaporated milk 

 with equal parts of water, by 

 weight; then weigh nine grams of 

 this dilution into the test bottles and 

 add one-half pipetteful of water.
