616 EXPEEIMENT STATION RECORD. 



The testing of parchment paper in regard to its utility for packing butter, 

 A. BuKx^ find A. Wolff (Milclnr. Zciilhl., 6 (1910), Xo. 6, pp. 2J,l-264, fig. 1).~ 

 The results are given of biological and chemical investigations of parchment 

 papers, two of which were of a sort which had contained butter infected with 

 mold. 



The most common kinds of mold found were PeniciJUum glaxicum and an un- 

 identified mold ; less often, Mucor, Aspergillus, and yeasts. Papers which con- 

 tained the most sugar were the most infected witli mold, but notwithstanding 

 this the authoi's found that other factors such as the salt content of butter had 

 a great influence on the vegetation, and particularly on the kind of fungus; 

 Mucor did not thrive in the butter wrapping tests. Stagnant and moist air are 

 also factors. AMth starch-glycerin parchment papers it was found that with 

 well-worked butters no fungus generally develops. 



The result of the chemical investigations showed that the sugar content with 

 26 papers was between and 25.78 per cent, and averaged 9.37 per cent. The 

 authors state that the sugar content of a good paper should not be over 8 per 

 cent, and that for water soluble material not over 10 per cent. The water con- 

 tent was found to be between 7.13 and 10.31 per cent. The average paper was 

 neutral to lltuuis. The ash content fluctuated between 0.34 and 17.1 per cent, 

 with an average of 4.59 per cent. According to the authors, only paper with 4 

 per cent ash should be allowed for butter wrapping. Lead was detected in only 

 4 cases. The highest amount found was 0.024 per cent. Iron was mostly only 

 found In traces, but in 2 cases it was 0.011 and 0.009 per cent, respectively.
