While the above description and the table are prepared to fit 
the analysis of 2 cc. samples of blood, which seems the desirable 
amount for ordinary purposes, either more or less may be taken, 
the volumes of dilute ammonia and ferricyanide used being 
changed proportionally. The following data show that good 
results are obtained with as much as 3 or as little as 1 ec. of blood,
