578 EXPERIMENT STATION EECOED. 



hot alcohol extract contains the highest percentage of phosphorus, the next 

 highest figure being found in the acetone-insoluble fraction of the same ex- 

 tract. In the case of the liver the phosphorus was practically all In the acetone- 

 insoluble fractions, and especially in that of the ether extract. In short, it is 

 apparent that the lipoids of egg yolk differ widely in certain chemical and 

 biochemical properties from those obtained from a mixture of several pigs' 

 livers." 



An attempt to preserve hemolytic com.plement in a permanent form, 

 H. R. Dean {Ahs. in Jour. Path, and Bad., 18 (1913), No: 1, pp. 118, 119).— 

 " The main object of these experiments was to obtain hemolytic complement in 

 a state in which it could be preserved and used in place of fresh serum. This 

 object was not attained. The method employed was such as to effect a separa- 

 tion of the lipoid and protein constituents of serum, and it is possibly of interest 

 to note that the separated protein was rich in mid-piece fraction, but contained 

 traces only of end-piece." 



Two important western poisonous plants, H. G. Knight {Proc. Soc. Prom. 

 Agr. Sci., 33 (1912), pp. 51-58). — The data here presented relating to the woody 

 aster and death camas have been previously noted (E. S. R., 28, p. 197). See 

 also a subsequent note (E. S. R., 29, p. 77). 



Studies in the toxicity of cotton-seed meal, W. A. Withers and B. J. Rat 

 {Proc. Soc. Prom. Agr. Sci., 33 (1912), pp. i9-2i).— Previously noted (E. S. R., 

 28, p. 197). 



A remedy for cotton-seed meal poisoning, W. A. Withers (North Carolina 

 Sta. Circ. 5 (1913), pp. 3). — The data here presented relating to experiments 

 with rabbits have previously been noted from another source (E. S. R., 29, p. 

 477). In addition, brief mention is made of preliminary tests with swine. 



Twelve pigs, weighing an average of 50 lbs., were fed daily 0.5 lb. of cotton-seed 

 meal and 1.5 lbs. of corn meal, the ration being increased as the pigs grew. 

 In addition, a solution of copperas was given to 6 of the pigs. At the time of 

 writing, or thirteen weeks after the experiments were commenced, 4 of the G 

 pigs receiving the cotton-seed meal without the iron salt had died and the 

 remaining 2 had a very unthrifty appearance and had made an average gain 

 of but 35 lbs. The 6 which had received an iron salt had gained au average 

 of 54 lbs. " Based upon these results, iron salt appears to be of value in 

 diminishing, if not entirely preventing, the harmful effects to swine of cotton- 

 seed meal feeding, provided that feeding is not in excess of the rate of 1 lb. of 

 meal daily to each 100 lbs. of live weight." 



The directions given for the preparation and use of the iron solution are as 

 follows: "Dissolve 1 lb. of copperas (ferrous sulphate) in a barrel (about 50 

 gal.) of water. For each pound of cotton-seed meal take 1 gal. of the solu- 

 tion, mix thoroughly daily for each 100-lb. pig. If the pig weighs only 50 lbs., 

 use half the amount of cotton-seed meal and one-half of the copperas solution." 



The diagnosis of anthrax according to Ascoli's and SchUtz-Pfeiler's 

 methods, F. Fischoeder (Ztschr. Infcktionslcrank. u. Ilyg. Hausticrc, 13 (1913), 

 No. 6, pp. 317-322). — Continuing previous work (E. S. R., 28, p. 477), the 

 author reports tests made with the Schiitz-Pfeiler precipitating serum. In all 

 cases where anthrax bacilli, whether living or dead, were present in the mate- 

 rial examined, anthrax could be diagnosed by the Schiitz-Pfeiler method. 



A diagnosis of anthrax sepsis with the lumbar puncture, L. Pollak 

 (Wiener Klin. Wclinschr., 25 (1912), No. J,3, pp. 1702-1704, fig. 1; ahs. in 

 Centbl. Bakt. [etc.l, 1. AM., Ref., 56 (1913), No. 12, p. 355).— A minute descrip- 

 tion of cases in which it was possible to detect the causative organism in the 

 cerebrospinal fluid. The fluid was centrifuged, and in the sediment the 

 Bacillus anthracis was noted by the usual method.
