0.90'/ invert sugar. The color was 4. flavor 3. and score 800: 

 depreciation from control, color I, flavor 1. and score 100. 



109. Number 109 was inoculated with gray yeast 24. The 

 organism made a remarkahle growth as evidenced by the deep 

 clouding of the material and a flaky sediment, as well as by the 

 semi-mycelial growth suspended in the sap. A distinctly yeasty 

 odor developed which hecame very offensive when the material 

 was heated for evaporation. The specific organism was recovered 

 in great numbers. 'The reaction was 41 X XX'ioo acid. The 

 sirup contained ^J.j^f sucrose and 2^.2^', invert sugar. The 

 color was 10, flavor 4, and score ^2^: depreciation from control. 

 color 7, flavor 2. and score i,y^. 



no. Number no was inoculated with gray yeast CXXI. 

 The organism was recovered from the material which developed 

 a dull brownish white appearance with clouding. The reaction 

 was 3.3^ X 100 acid. The sirup contained 07.0(1', sucn 

 and 1.74X invert sugar. The color was 6, flavor 4. and score 

 625; depreciation from control, color 3, flavor 2, and score 275. 



1 it. Number 111 was inoculated with green mold CCCI 

 belonging to the Eurotium genus. The organism made moder- 

 ate growth as could he seen by the tufts of mycelium developing 

 in the material and also from the plates. The reaction was 2' , 

 X 100 acid. The sirup contained 1)3.31 X sucrose and 4.30 

 invert sugar. The color was 7. flavor 4. and score 600: depreci- 

 ation from control, flavor 4. color 2. and score 300. 



112. Number 112 was the control sterilized and held in the 

 incubator without inoculation. The reaction was 1% X mo 

 acid. The sirup contained 97.60^ sucrose and 1.11X invert 

 sugar. The color was 5, flavor 2, and score 850; depreciation 

 from control (number 105), color 2, flavor o. and score 50.
