66 iEXPERIMENT STATION RECORD. 



ferent periods of the march. TTie ration of jam was increased and picliles 

 were added, but this latter addition was not appreciated by the men. The total 

 ration provided 142 gni. of protein per man per day during the first weeli, and 

 175 gm. during the second weelv of the mai'ch. The average energy supplied was 

 4,511 calories per man per day. The total muscular worli, external and internal, 

 was calculated as 3,9S9 calories per man per day, an amount practically identi- 

 cal with that noted during the previous march. 



The weight curves show an average gain during the first few days, next a 

 slight fall, followed by a second gain, and a second smaller fall. Instead of 

 an average loss such as appeared during the previous year, there was an aver- 

 age gain of 0.16 kg. in the weight of the men at the end of the marcli. They 

 showed no symptoms of underfeeding, as in the previous case, and considered 

 their diet in every way adequate. 



In the opinion of the committee, a ration furnishing 4,500 calories of energy 

 per man per day, and containing a larger proportion of fat and sugar than that 

 found in the present ration, should be adopted by the British Army. 



It is stated that the nitrogen balance of 2 of the oflScers during the second 

 experimental march will be published later. 



The disappearance of beri-beri from the Philippine (native) scouts, W. P. 

 Chambex^lain {Military Surg., 2S (1011), No. 5, i)p. 509-522). — During the year 

 1910 changes were made in the rations for Philippine scouts which slightly pre- 

 ceded the change which was effected in the general Philippine ration. This 

 preliminary change did not substitute unpolished for polished rice, but reduced 

 the amount of polished rice, substituting for it legumes, ginger root, and 

 various native vegetables. Aside from the change in the diet, conditions among 

 the Philippine scouts remained practically the same as those in other native 

 troops. 



The health sheet of the scouts showed no remarl^able changes except the 

 disappearance of beri-bori. The Board for the Study of Tropical Diseases as 

 They Exist in the Philippine Islands, which suggested the' change, believes that 

 the disappearance of the disease is due to the substitution of other vegetables 

 for part of the polished rice. It does not hold that this contradicts the polished 

 rice theory of beri-beri, but rather that it supports it, the substitution of vege- 

 tables for part of the polished rice in its opinion furnishing necessary mineral 

 matters lacking in the jwlished rice. 



Report of the U. S. Army Board for the Study of Tropical Diseases as 

 They Exist in the Philippine Islands, W. P. Chamberlain, H. D. Bloom- 

 BKRGii, and E. B. Yeddeu {MUitunj Surf/., 2>S (1011), No. .',, pp. Ji.>i5-.>,52) . — Data 

 are summarized regarding the disappearance of beri-beri from the native Philip- 

 pine scouts which followed a change in ration. The preparation of rice of dif- 

 ferent sorts is discussed and some data presented regarding the experimental 

 work with poultry on rice in relation to the development of polyneuritis. 



The influence of fat in the food upon the body fat of carp, J, Konig, A. 

 Thienemann, and R. Limprich (Ztschr. Untcrsuch. Nahr. u. Gcnussmtl., 23 

 (1912), No. 5, pp. 177-197). — Among the conclusions drawn as the result of 

 these investigations were that feeds with a high fat content produced a high 

 fat content in the flesh of fish. Phytosterin was not detected in the hotly fat. 

 The nature of the food fat or its cleavage products affected the taste of the 

 fish, and in certain cases it became unpalatable. Analyses of the experimental 

 animals and of several other species of fish are reported. 



The condition of the liver as influenced by various kinds of food fats, 

 S. S. Chalatow (Arch. Path. Anat. u. Physioh [Virchow], 207 (1912). No. 3, 

 pp. fi52-Ji69). — The author fed rabbits and white rats on diets consisting in 

 different instances of suntlower seed oil, beef tallow, liver fat, ox brain, and
