however, removes such risks. The control of body as well as mind, involved 

 in the race, the author regards as valuable discipline. 



The influence of fatig-ue on the amounts present in blood serum of 

 dialyzable compounds showing triketohydrindene hydrate reaction, E 

 Abdeehalden and A. E. Lamp6 (Hoppe-Scyler's Ztschr. Physiol. Chem 85 

 (1913), No. 1-2, pp. 136-142).— FoUowmg the previously described method' for 

 detecting amino acid in blood serum (E. S. R., 26, p. 804), the authors tested 

 the blood of dogs before and after violent exercise in a treadmill, but were 

 unable to note any characteristic differences in the amino acid content of the 

 2 types of serum. 



The influence of the cerebrum on the metabolism of matter and energy 

 K. Hannemann (Biochem. Ztschr., 53 {1913), No. 1-2, pp. 80-99).— The respira- 

 tion and calorimetric experiments here reported were made with laboratory 

 animals (frogs). In one series, the entire cerebrum was removed, in another 

 the cerebral hemispheres; and in a third the optical lobe. The author sum- 

 marizes his results as follows : 



(1) The removal of the entire cerebrum, the hemispheres, or the optical lobe 

 produced a marked increase in the gaseous exchange, which lasted for several 

 days. (2) The oxygen as well as the carbon dioxid output was increased the 

 carbon dioxid increase being the greater save in those cases where' the 

 hemispheres alone had been removed. (3) Calorimetric observations showed 

 that an increase of heat production accompanied the increased gaseous exchange.

 (1913), No. 1-2, pp. 1-20).— A theoretical technical discussion of the theorem 

 that "every isothermal physical and chemical process occurring in nature takes 

 place in such wise that the free energy in the body concerned is lessened " with 

 special reference to the transformations of energy in the animal organism

Feed control officials' convention {Anier. Hay, Flour, and Feed Jour 2k 

 (1913), No. 1, pp. 19-34, figs. 10). -An account of the fifth annual convention of 

 the Association of Feed Control Officials, held at Washington, D. C, November 

 17 and 18, 1913. Addresses were given on the following subjects : Screenings 

 and weed seeds as adulterants in commercial feeds; observations relating to 

 British feeding stuffs; the feed industry in the United States; and the com- 

 position of cotton-seed meal. 



The composition of cotton-seed meal, G. S. Fraps {Amer. Hay, Flour and 

 Feed Jour 24 (1913), No. 1, pp. 28-31).-ln this paper, which was presented 

 at the fifth annual convention of the Association of Feed Control Officials the 

 need of a fiber standard for cotton-seed meal in addition to the protein or fat 

 standards is pointed out. It is shown wherein these latter standards alone 

 permit the admixture of hulls with the meal, thus reducing its feeding value, 

 though remaining within the bounds of a guarantied protein analysis 



[Analyses of feeding stuffs] (Min. Agr. et Trav. Pub. [Belgium] Off. 

 Rural Raps, et Gommuns., 1913, No. 7, pp. m, log, 124-126) .-Analyses are 

 reported of cotton-seed meal, linseed meal, cacao hulls, perilla cake, and sugar 

 beets.
