166 EXPERIMENT STATION EECORD. [Vol.36 



packing is found at Chicago and Missouri River points. . . . Public abattoirs have 

 been established in 22 cities in 13 States. Seven of these establishments are 

 owned and operated by the city, while the remaining 15 are owned privately and 

 operated under city inspection. Local packing houses are distributed mainly 

 in the more important live-stock producing States and in sections remote from 

 live-stock markets and packing-house centers. Cooperative packing houses 

 recently have been promoted in a number of communities in six States, . . . 



"The marketing of farm-prepared meats, although comparatively limited 

 in relation to the industry as a whole, is practiced more or less in almost all 

 parts of the country. The curing of meat at ice plants is a recent development 

 in local marketing in the South. . . . The parcel-post method of marketing 

 meat is limited in comparison with the other methods, yet the amount thus 

 marketed is considerable as a sum total. 



" The correlation between average live-stock and meat prices is closer than 

 generally is understood. Daily fluctuations in live-stock quotations frequently 

 are large and abrupt and constitute one of the most adverse features of live- 

 stock market conditions. Meat prices from day to day tend to follow general 

 averages of previous years more closely. The results of investigations of the 

 marketing of 9 lots of cattle through centralized markets show that from 

 54 to 85 per cent of the gross returns was received by the stockmen, from 2 to 5 

 per cent was absorbed by marketing expenses, 2 to 9 per cent was received gross 

 by packers, and 8 to 33 per cent by retailers. The retailers' gross margin, as 

 shown from the results of marketing locally five shipments of cattle, varied 

 from 15 to 38 per cent of the gross returns. From 62 to 84 per cent of the 

 gross returns on these cattle was received by the owner." 



The marketing of live stock, D. A. Gaumnitz (South St. Paul, Minn.: W. M. 

 Camphell Commission Co., 1916, pp. J^2). — This treats of methods of marketing 

 live stock, preparing animals for shipment, loading, feeding in transit, and 

 other related topics. 



On the g'eneral theory of multiple contingency with special reference to 

 partial contingency, K. Pearson (Biometrika, 11 (1916), No. 3, pp. 145-158). — 

 A mathematical discussion of the theories of multiple and partial contingency, 

 in which a large number of formulas are set forth. 



On certain probable errors and correlation coefficients of multiple fre- 

 quency distributions with skew regression, L. Isserlis (Biometrika, 11 (1916), 

 No. 3, pp. 185-190). — Formulas are given for use in the systematic investigation 

 of statistical constants of multiple correlation and of their probable errors in 

 cases in which skew regression is involved. 



On the probable error of a coefficient of contingency without approxima- 

 tion, A. W. Young and K. Pearson (Biometrika, 11 (1916), No. 3, pp. 215-230).— 

 In this paper the authors consider the variation of (p^ on the hypothesis of 

 Pearson * but without approximation. 



On some novel properties of partial and multiple correlation coefficients 

 in a universe of manifold characteristics, K. Pearson (Biometrika, 11 (1916), 

 No. 3, pp. 231-238). — The object of this paper, which is of interest to statis- 

 ticians and biometricians, is to show by direct determinantal analysis certain 

 relations known and unknown between the higher multiple and partial corre- 

 lation coefficients. 



On the application of " goodness of fit " tables to test regression curves 

 and theoretical curves used to describe observational or experimental data, 

 K. Pearson (Biometrika, 11 (1916), No. 3, pp. 239-261, fig. i).— This is a discus- 

 sion of the " goodness of fit " and its application in statistics and physics.
