174 EXPERIMENT STATION RECORD. 



and extended. Sulphur also was found to occur chiefly in organic forms, as has 

 been pointed out bj^ other observers. 



The vegetable material insoluble in acid gastric juice contained nitrogen, 

 phosphorus, and suli)hur in organic compounds, but no definite relation between 

 Ihesc elements or between any two of them could be noted in the different 

 vegetable products studied. 



In feeding experiments with sheep, it was found that feces contained a larger 

 amount of organic ph()si)horus and sulphur than was to be expected from the 

 iharacter of the rations (hay with and without oats). Metabolic products 

 were present in the feces containing the insoluble phosphorus and suliihur 

 compounds, which were also insoluble in acid gastric juice. 



According to the author, the nature of the organic sulphur compounds is not 

 known, particularly those which occiir in plants and are insoluble in acid gastric 

 juice and also the insoluble organic sulphur compounds i^emaining in the feces. 



Elimination of phosphorus by Herbivora, A. Gouin and P. Andouakd 

 (Coinpt. Rend. 8oc. Biol. [Paris], (I't (1908), No. 3, pp. 133-135).— The authors 

 studied the effect of different rations on the excretion of phosphorus by Herbiv- 

 ora with special reference to the observed fact that with young animals the 

 urine contains practically all the phosphates excreted, while such is not the case 

 with older animals. 



The action of fresh cola nuts on muscular work, J. Chevalier and Alquier 

 iCompt. Rend. Acad. 8ci. [Paris], 1J,6 (1908), No. 2, pp. 86-88).— Experiments 

 with 2 horses showed that more work was performed on a ration with than 

 without fresh cola nuts. A loss in body weight and increased bod.v temperature 

 were noted during the cola nut period and the authors conclude that the extra 

 work is performed at the expense of body material. Cola nuts are regarded as 

 a stimulant and their use is not considered desirable except when forced work 

 is necessary. 



The influence of sexual function on metabolism, F. Tangl (Landiv. Jahrh. 

 37 (1908) No. 1, pp. Ji5-50). — In the studies reported, when a stallion covered 

 a mare the quantity of urine was not increased nor was the renal excretion of 

 nitrogen or phosphorus. This showed, according to the author, that the meta- 

 bolism of protein and of phosphorus yielding bodies is not materially increased, 

 and so he concludes that it is not necessary to provide stallions with a ration 

 especially rich in phosphorus. 



The.efEects of environment and nutrition upon fertility, F. H. A. Marshall 

 (8ci. Prog. Ticentieth Cent., 2 (1908), No. 7, pp. 369-377).— The effect of feed 

 on productivity and character of the young and related questions are discussed 

 and data bearing on this subject summarized. 



According to the author, the largest percentage of lambs w^as obtained, in 

 tests which he quotes, from flocks kept on grass during the greater part of the 

 year, but artificially stimulated by feeding the ewes for a time turnips, oats, 

 dried grain, maize, or other similar feed. The data summarized fully confirm 

 the conclusion " that stimulation of the generative organs of sheep by a system 

 of special feeding at the beginning of the breeding season results in an increased 

 crop of lambs at the following lambing season. The twins appear almost 

 invariably to have been born early during lambing, thus showing that the 

 reproductive activity of the ewes is usually greatest at the beginning of the 

 breeding season." 



Experiments in calf feeding, A. Gouin and P. Andouard (8oc. Aliment. 

 Rationn. BHail, Comptc Rendu 11. Cong., 1907, pp. 11-28, 127-130).— A paper 

 with discussion summarizing the authors' experiments in which rations with 

 and without skim milk were used in calf feeding and potassium phosphates, rock 

 phosphate, sweetbread, thyroid, protylin, and powdered bone were added to" the
