EXPERIMENT STATION RECORD. 



[Vol. 43 



this was due to a compensatory flow of liquid from the muscles to the blood 

 was proved by experiments on cats. 



Contribution to the knowledge of the nonprotein nitrogen of human 

 blood. — I, Material on the general chemical pathology of the entire sys- 

 tem, J. Feigl {Biochem. Ztschr., 94 (1919), No. 1-2, pp. 84-128; ahs. in Chem. 

 Abs., 13 (1919), No. 20, p. 2559). — This is a general summary and discussion of 

 the significance of the variations in the nonprotein nitrogen of the blood in 

 pathological conditions as reported by various authors. 



Nutrition laboratory, F. G. Bf:NEDiCT (Carnegie Inst. Wash. Year Book, 18 

 (1919), pp. 265-276). — This is the usual annual report of the nutrition labora- 

 tory of the Carnegie Institution (E. S. R., 43, p. 66). 



The additions to equipment during the year include a pursuit pendulum for 

 testing the eye-hand pursuit coordination, a pursuit meter apparatus for re- 

 cording adequacy of motor adjustment, and a respiration chamber for large 

 animals which has been constructed at the New Hampshire Experiment Station 

 and is being used in aa investigation of the metabolism of full-grown steers 

 during undernutrition and in the subsequent period of realimentation. 



The report contains, as usual, brief accounts of investigations in progress and 

 abstracts of publications issued during the year. These have for the most part 

 been noted from the original sources. 



ANIMAL PRODUCTION. 



Experiments in the utilization of different feeding stuffs; with a note on 

 the determination of the digestibility of protein, A. Morgen, C. Beger, and 

 E. Ohlmer (Landiv. Vers. Sta., 88 (1916), No. 3-4, pp. 243-260) .—Bigestion 

 trials with sheep and 3-months-old pigs are reported. The following table 

 gives the major results : 



Digestion coefficients for various feeding stuffs. 



1 Considered doubtful. 



An African palm of the genus Hyphsene furnished the red " ivory-nut " by- 

 products. The gray by-products were from the true ivory palm (genus 

 Phytelephas). The meal in both cases contained more protein, more crude 

 fiber, and more ash than the chips. " Reindeer moss " is the lichen Cladonia 

 rangiferina. 



It was also found that sheep digested 79.5 per cent of the organic matter in 

 bone meal and 75.3 per cent of the organic matter in blood meal. 



The digestion coefficients for protein given in the table were computed by 

 ignoring the nitrogen in the pepsin HCl-soluble fraction of the feces (Stutzer's 

 correction for excreted nitrogen). The feeds were all low in protein, and the
