barley, oats, rye, and buckwheat, both decorticated and milled from the whole 

 grain ; raw, cooked, and commercially dehydrated potato ; dried apples ; and 

 breads made from white tlour, white flour with dried blood, and rye meal 

 with dried blood. 



The resulting weight curves of the animals fed dried apples, potato flakes, 

 and raw potatoes all resembled in places the typical curve of inanition, and in 

 others the curve resulting from a qualitatively insufiicient diet. The other 

 curves, with the exception of that of the rye blood bread, showed a qualitative 

 insufficiency. 



The results are considered to give further proof of the value of incorporating 

 some of the bran in the flour, and to cast doubt on the advisability of using 

 much commercially dried potato in bread making. 



The resistance of red blood corpuscles under conditions of nitrogen de- 

 ficiency and of inanition, D. Acel {BiocJicm. Ztschr., 95 {1919), No. 3-^, pp. 

 211-219). — Data obtained in feeding experiments with dogs, mice, and guinea 

 pigs are reported, which indicate that diets of sufficient energy value but pro- 

 ducing a negative nitrogen balance have no effect on the red blood cells, while 

 diets of insufficient energy value lower their resistance. 



Brains and spinal cord of slaughtered animals as food materials, A. 

 Weitzel (Arb. Reichsgsndh'sant, 51 {1919), No. 2. pp. 330-392).— Proximate 

 analyses are reported of the brains and spinal cord of cows, pigs, and calves 

 with a view to their utilization as food materials. 



The brains were found to be slightly higher in protein and decidedly lower 

 in ether-soluble substances (fat) than the spinal cord of the same animals. 

 The highest values for both fat and protein were found in beef organs. 



On account of their relatively high content in protein (8.22 to 10.44 per 

 cent) and in fat (8.18 to 25 per cent), and the absence of carbohydrates, the 

 author recommends the use of these materials as food for diabetic patients. 



The composition of vegetables and their waste products, M. P. von 

 ScHLEiNiTz {Landw. Jahrb., 52 {1918), No. 2, pp. 131-278). — For the purpose of 

 determining which vegetables should be considered as foods and which as 

 luxuries, extensive analyses have been made of the edible portion, of the 

 kitchen waste, and of the garden waste of the common vegetables. These 

 analyses are assembled in the following tables : 



Proximate analyses of the vegetables in terras of the dry and the fresh ma- 

 terial, proximate analyses of the garden waste in percentage of the dry and 

 of the fresh material, proximate analyses of the kitchen waste calculated to the 

 same basis, and the weight in grams of the edible portion, and of the kitchen 

 waste in 1 kg. of the vegetables as marketed. The vegetables included 

 asparagus, rhubarb, head lettuce, kohlrabi tops, spinach, mangolds, beans, 

 peas, cucumbers, onions, celery, carrots, red beets, swedes, cauliflower, red and 

 white cabbage, Brussels sprouts, and kale. 



Report on the antiberiberi vitamin content and antiscorbutic property 

 of sun-dried vegetables, J. A. Shorten and G. Roy {Indian Jour. Med. Re- 

 search, Spec. Indian Sci. Cong. No., 1919, pp. 60-78, pJs. 13, figs. 2).— With a 

 view to determining to what extent sun-dried vegetable products can replace 

 fresh vegetables in an army ration, carrots, onions, spinach, and cabbage sun- 

 dried by the process described by Howard (E. S. R., 41, p. 116) were tested 

 for their content in antiberiberi vitamin by preventive feeding experiments 

 with fowls, and for antiscorbutic vitamin by experiments with guinea pigs. 



All of the vegetables possessed antineuritic properties, as shown by the fact 

 that the addition of 5 gm. (dry) daily of the cooked vegetable was sufficient 

 to prevent the onset of beriberi in fowls on a basal ration of polished rice. 

 Carrots, cabbage, and onions showed antiscorbutic properties, in that 1.6 gm.
