EXPERIMENT STATION RECORD. 



Report of a practical test of the use of the emergency ration by 

 United States troops on active service, C. Smart (Com. Gen. Sub- 

 sist. JJ. 8. Army Ilpt. 1897, pp. 12-19). — Two tests were made of the 

 emergency ration of the United States Army with cavalry soldiers near 

 Fort Sill, Oklahoma. In one test 46 officers and men, averaging 158 

 lbs. in weight, were given the emergency ration for 10 days. The ration 

 consisted of 12 oz. bacon, 11.2 oz. hard bread, 5.4 oz. flour, 2.4 oz. 

 beans, 1.2 oz. sugar, 10 oz. potatoes, and some coffee, salt, and pepper. 

 A portion of the food was not eaten. The average quantity consumed 

 per man per day was 10.2 oz. bacon, 11.2 oz. hard bread. 2.2 oz. flour, 0.8 

 oz. beans, 16 oz. potatoes, and 0.05 oz. sugar. This was calculated to 

 furnish 3.32 oz. protein, 7.68 oz. fat, aud 15 oz. carbohydrates with a 

 fuel value of 4,145 calories. The average loss in weight per man was 

 1.35 lbs. 



The special emergency ration was tested with 10 men. This con- 

 sisted of 8 oz. hard bread, 5 oz. bacon, 2 oz. pea meal, with coffee, sac- 

 charin, salt, pepper, and tobacco. 



During a 10 days' test the men marched on an average 21 miles a 

 day, and lost 2.935 lbs. in weight. They remained in good health and 

 spirits. All the ration was consumed. It was calculated that it fur- 

 nished 2.128 oz. protein, 3.809 oz. fat, and 6.93 oz. carbohydrates and 

 yielded 2,055 calories. 



The chemical composition and nutritive value of some edible 

 American fungi, L. B. Mendel (Amer. Jour. Physiol., 1 (lS!>s) J Xo. 

 11, pp. 225-238). — To determine their nutritive value a number of edible 

 fungi were analyzed aud their digestibility determined by methods of 

 artificial digestion.
