One of the filtrate or the clear supernatant fluid obtained on centrifugal-ization is withdrawn, put into the plain test-tube, and heated carefully over thenaked flame. The contents of the tube are boiled until all but 2 or 3 drops of thesolution is evaporated. One-half of the 10 per cent sodium carbonate solutionis then added and the tube heated again until the contents are concentrated

The contents of the tube are boiled until all but 2 or 3 drops of thesolution is evaporated. One-half of the 10 per cent sodium carbonate solutionis then added and the tube heated again until the contents are concentrated toa small volume equal to about 2 or 3 drops. The color of the fluid changes fromyellow to deep red or reddish brown and the reaction is completed. Three or 4 drops of distilled water are added and the tube warmed gently. Thecontents are then transferred to the graduated tube of the boiling tube is rinsed several times with water (using ordy 3 or 4 drops at atime). The tube is warmed with each rinsing before transferring the contents tothe graduated tube. The volume of fluid is then made up to the mark 50 on
