564 EXPERIMENT STATION RECORD. [Vol. 43 



These analyses show that the first two operations of pearling result in pot 

 barley, bringing about the removal of most of the husk and carrying with it 

 the greater part of the fiber and silica. The composition of the pot barley as 

 compared with the original barley shows a loss of 22 per cent of the total 

 material, 25 per cent of the protein, 41 per cent of the fat, and 50 per cent 

 of the mineral constituents. In continuing the operations to produce the pearl 

 barley, the loss in different constituents was as follows : Sixty-five per cent 

 of the barley material, 74 per cent of the protein, from 80 to 85 per cent of the 

 fat, P.Os, K:0, CaO, and MgO ; and from 97 to 98 per cent of the fiber and SOz. 



Attention is called to the great waste of available food material involved in 

 carrying the pearling beyond the pot-barley stage. "Assuming that 5,000,000 

 bu. of barley are being pearled yearly, 52,000 tons of barley material, consisting 

 of over 1,000 tons each of fat and mineral ingredients and 6,700 tons of protein 

 are removed." 



Digestibility of steam-cooked soy beans and peanuts, A. D. Holmes (;Jour. 

 Anier. Med. Assoc, 74 (1920), No. 12, pp. 798-SW).— When fed to healthy young 

 men, steam-cooked soy beans and peanuts were both found to be well utilized, 

 the carbohydrates in the entire diet in which the legumes formed a prominent 

 part being 97 per cent digested in the case of the soy beans and 99 per cent 

 in the case of the peanuts. The average digestibility of the soy bean protein 

 was 79.9 per cent and of the peanut protein 92.8 per cent. 



The fact that large quantities of soy beans and peanuts were consumed 

 daily for three successive days without causing any physiological disturbances 

 indicates that these foods cooked for two hours by steam at 15 lbs. pressure 

 are well tolerated by the human body. It is concluded that soy beans and 

 peanuts are specially valuable for human food as compared with other legumes 

 which have been studied with the same thoroughness. 



The drying of bananas, W. Bukns and P. G. Joshi {Agr. Jmir. India, 15 

 (1920), NO. 2, pp. 166-173. flgs. 3). — The authors have succeeded in drying 

 bananas in India by exposing them to the sun under glass in an apparatus 

 shaped somewhat like a museum case. The peeled bananas require from four 

 to six days to dry thoroughly. It is said that from 20 to 30 moderate-sized 

 bananas makes 1 lb. of dried material, which has good keeping qualities and 

 can be eaten raw or used in the making of jam or various Indian food dishes. 



Industrial medicine and surgery: [Food in industrial plants], H. E. 

 Mock (^Philadelphia: W. B. Saunders Co., 1919, pp. 846, figs. 2iO).— Industrial 

 health service, prevention of disease, industrial medicine, industrial surgery, 

 compensation, insurance, medicolegal phases, and reconstruction are discussed. 

 The first-mentioned section contains a chapter on food, in which the need for 

 attention to food for employees is insisted upon and ways are suggested whereby 

 the physician or medical staff of the enterprise may be of assistance. The need 

 for proper places where employees may eat the food brought with them, the 

 advantages of a restaurant or eating place, and similar matters are discussed. 

 If a restaurant is maintained, it is pointed out there should be periodical medical 

 examinations of all employees and sanitary inspection of storerooms, dining 

 rooms, etc., while food should be frequently inspected. The milk and ice cream 

 should be bacteriologically examined, and every effort made to see that 

 nourishing, well-prepared food is served. A score card for the frequent in- 

 spection of the restaurant is suggested. Some information is also given regard- 

 ing plans followed in industry. 



Studies on adaptation of man to high altitudes, I-V, E. S. Sundstroem 

 (Univ. Cal. Pubs. Physiol, 5 (1919), Nos. 5, pp. 71-86; 6, pp. 87-104; 7, pp. 105- 

 112; 8, pp. 113-120; 9, pp. 121-132) .—This is a series of papers dealing with 

 different phases of the adaptation of two persons (the author and his wife) in
