analysis (E. S. IJ., 5, ]). 530); and (2) the method of composite samp- 

 ling without addition of any preservatives. As the potassium bichro- 

 mate, according to recent Danisli exiierience. may lead to "certain 

 peculiar mistakes," the author recommends keeping composite samples 

 of milk in a well-stoppered bottle without a preservative, and at the 

 end of 2 to 3 weeks adding a definite small quantity of concentrated 

 ammonia and determining the fat, according to the method described 

 by him {Milch Ztg., 23 (1894), p. 247).— f. w. woll.
