258 Bacteriological examination of glassware or china for sanitary quality. 

 C. R. Fellers, A. S. Levine, and E. W. Harvey. Amer. Jour. Pub. Health 

 26 (12):1211-1214. 1936. 



A comparison of various methods for the bacteriological determination of the sanitary 

 condition of drinking glasses and eating utensils showed the swab method to be the most 

 satisfactory. Practical tests of the method showed it to be rapid, simple, and reliable. It 

 should pro"e useful to health laboratories as a routine method for checking the cleansing 

 and sterilization of utensils in establishments dispensing food and beverages. 



260 Composition and nutritive studies on blueberries. Oreana A. Merriam 

 and Carl R. Fellers. Food Research 1 (6):501-512. 1936. 



Analyses of fresh and moisture-free wild and cultivated blueberries are reported. The 

 fruit contained from 1 to 2 units of vitamin C and about 1 unit of vitamin A per gram. 

 Froaen blueberries contained as much vitamin C as fresh, but defrosting was destructive 

 to this vitamin. Canning partially preserved the vitamin C. Blueberries contained only a 

 trace of benzoic acid. When fed in 300 -gram amounts to young men, they did not lower the 

 blood alkali reserve, nor did they increase urinary acidity. 



262 Cytospora canker of spruces. C. J. Gilgut. Twelfth Natl. Shade Tree 

 Conf. Proc. 1936. 



The dying of the lower limbs of Colorado blue spruce, long considered a natural occur- 

 rence due to age, is here shown to be caused by the fungus, Cytospora Kunzei. The disease 

 was produced artificially by inoculation, but infection occurred only when wounds were 

 made in the bark. This is the most serious disease of Colorado blue spruce and Norway 

 spruce in Massachusetts, where these trees are used extensively as ornamentals.
