262 EXPERIMENT STATION RECORD. 



Food inspection decisions {U. 8. Dept. Agr., Food Insp. Decisions 74, pp. 3; 

 75, pp. 2; 76, pp. 13). — These publications include, respectively, the decisions 

 which have been rendered under the provision of the pure food law regarding 

 certificates for imported meats and meat-food products of cattle, sheep, swine, 

 and goats ; the labeling of mixtures of cane and maple sirups ; and dyes, chem- 

 icals, and preservatives in foods. 



Adulteration of food {Ri)t. Inland Rev. Canada, 1906, pt. 3, pp. 375).— A 

 summary of data showing the scope and extent of the year's woi'k of the 

 Canadian Inland Revenue Department in respect to food and food adulteration. 

 The results have appeared in detail in Bulletins 106 to 124 of the department, 

 which are reprinted as appendixes. These bulletins have been noted from time 

 to time as they appeared. 



Law with respect to foods in Germany, G. Lebbin and G. Baum (Deutsches 

 Nahrungsmittelrecht. Berlin: J. Guttentay, 1907, vols. 1, pp. 555; 2, pp. 22 i; 

 rev. in Chem. Ztg., 31 (1907), No. 28, p. 361). — This work is designed for the 

 use of students, physicians, chemists, and manufacturers. The first volume is 

 concerned with fines, duties, and other legal questions, while the second con- 

 tains a summary of data on analytical methods with special reference to the 

 needs of legal chemists. 



Observations on human chyle, T. Solimann {Amer. Jonr. Physiol., 17 

 (1907), No. 5, pp. Ji87--i9lj. — The chyle was obtained from a subject who had 

 been wounded in the thoracic duct and operated on in such a way that the lymph 

 flowed fi'om the wound in a continuous stream for several days. When the sub- 

 ject fasted the chyle was clear ; at other times it was more or less creamy in 

 appearance and when creamy would clot or jelly on standing. Analyses of the 

 chyle are reported as well as data upon the excretion of different drugs in chyle 

 and related topics. 



Do eggs affect the excretion of uric acid? P. Fauvel (Co)npt. Rend. Soc. 

 Biol. [Paris], 62 (1907). J^o. 14, pp. 730-732).— In the experiment reported 150 

 gm. egg per day was added to an otherwise purin-free diet, this period being pre- 

 ceded and followed by a similar diet without eggs. As shown by the data re- 

 corded, eggs did not increase the uric-acid output or the excretion of xantho- 

 uric bodies. 



Total metabolism of iron and calciiim in man, H. C. Sherman (Proc. Soc. 

 Expt. Biol, and Med., // (1906), No. 2, pp. 21, 22; abs. in Chem. Abs., 1 (1907), 

 No. 5, p. 582). — The balance of income and outgo of iron and calcium was de- 

 termined in 3-day experiments with man. " On a diet with 0.0057 iron and 

 2.65 calcium oxid there was equilibrium with respect to iron and retention of 

 calcium. With 0.0065 iron and 0.14 lime, or 0.0071 iron and 0.13 calcium oxid, 

 there were losses of both iron and calcium." The results confirm the statement 

 previously made that a deficiency of calcium in the diet may lead to a siuud- 

 taneous loss of iron. 



Thermodynamics of muscles, K. Bxjbkeb (Miinchen. Med. Wchnschr., 51^ 

 (1907), No. 2, pp. 59-62; abs. in Zentbl. Qesam. Physiol, u. Path. Stoffivechsels, 

 n. ser., 2 (1907), No. 6, p. 222). — The author's experimental methods permit the 

 study of muscle activity and show that under the different external and internal 

 influences which different seasons bring about the muscle possesses varying 

 quantities of energj-yielding material. It also appears from his results that in 

 the case of raising and lowering a weight isothermic energy is involved in the 

 lowering, though in much less degree, as well as in the raising. Other ques- 

 tions are also considered. 



Protean cleavage and labored breathing, C. Voit (Ztschr. Biol., Ji9 (1907), 

 No. 1, pp. 1-36). — An extended summary and discussion of the changes in niti'o- 

 gen excretion observed when breathing becomes labored, based in a large 

 measure upon the author's own investigations.
