On the protective and curative properties of certain foodstuffs against 

 polyneuritis induced in birds by a diet of polished I'ice, II, E. A. Cooper 

 {Jour. Hyg. [Cambridge], 14 (1914), No. 1, pp. 12-22). — Continuing previous 

 work (B. S. R., 28, p. 760), experiments are reported with pigeons in which 

 the protective power of varioiLS substances was studied to prevent polyneuritis 

 following a diet of polished rice. The author's general conclusions follow. 



"Nuts (husked filberts) are very efficient in preventing polyneuritis, being 

 even superior to lentils and husked barley. Cheddar cheese, on the other hand, 

 even in considerable amount, has no preventive effect. 



" Malt extract taken from two different samples readily cured polyneuritis in 

 pigeons. A third sample, however, even in large doses had no curative action. 



" For the prevention of beri-beri, egg yolk, heart muscle, liver, nuts, barley, 

 and lentils can be recommended as suitable foodstuffs with which to supple- 

 ment the polished rice diet. As meat (voluntary muscle) has been frequently 

 found to be ineffective in preventing epidemics of beri-beri, its replacement 

 by heart and liver in mixed diets would be a considerable improvement, because 

 not only are these tissues when suitably prepare<i as nutritious as voluntary 

 muscle but they also contain the .antineuritic substances in much higher con- 

 centration." 



Phosphates and wheat bran in animal nutrition, P. Carles (Rupert. Pharm. 

 et Jour. Chini. MM., S. ser., 25 {1913), No. 3, pp. 97-99).— The relative values of 

 mineral phosphates, animal phosphates such as dried and powdered bones, and 

 wheat bran are discussed. 



The author regards mineral phosphates as worthless, while animal phosphates 

 show a marked beneficial effect upon animals. Wheat bran is superior to 

 animal phosphates, because of its stability and good keeping quality. 



Data are given regarding the amount of phosphates present in the materials 

 which the author discusses. 



Behavior and effect of sugars of different sorts in the body, P. Albertoni 

 (Ergeh. Physiol., U {191J,), pp. J,31-Jt'13).—A-a exhaustive digest of experi- 

 mental data. 



The effect of sugars on the secretions, D. lo Monaco {Arch. Farmacol. Sper. 

 e Sci. Aff., 17 {19 Vf), Noft. 3, pp. 127-1 U; h PP- 1-^5-177).— This is a progress 

 report of experiments in which are being studied the effects of sugars upon the 

 .salivary, intestinal, and renal secretions. The sugars were taken into the body 

 in part via the stomach and in some cases by means of intra venal or sub- 

 cutaneous injections. A digest of the work done by others along this line is 

 given. Extended data of the experiments are presented, but no genera] con- 

 clusions are drawn, as further work is to be reported on the subject. 



The comparative value of various sugars in the feeding of infants, C. C. 

 Haskell {Arch. Ped., SO {WIS), No. 8, pp. 572-587; IJlly Set. BuL, 1. ser.. No. 

 Jf {19U), pp. 136-150). — The data obtained in tests with infants, either con- 

 valescent or suffering with more or less chronic conditions, indicate, according 

 to the author, that the best results were obtained with a diet containing " malt- 

 soup extract," with lactose and a mixture of dextrins with maltose following in 

 the order named. He points out that the conclusions have nothing to do with 

 the selection of sugar for normal infants, and states that he has " seen nothing 

 in the literature to prove nor have we made any observations in support of the 

 contention that the maltose-dextrin mixtures are in any way superior to lactose 

 for addition to the food of the average sound Infant." 



Industrial maltose, C. B. Dubyea {Jour. Indus, and Engin. Chan., 6 (i9i4).
