78 EXPERIMENT STATION" RECORD. [Vol.38 



Soft cheese making, R. W. Brown and M, Mobtensen {Iowa Sta. Circ. S8 

 (1916), pp. 4).— Brief directions for making Neufcliatel, pimento, olive cream, 

 sandwicli nut, cream, club, cottage, and butternut cheeses. 



How to make cottage cheese on the farm, K. J. Matheson and F. R. Cam- 

 mack {U. S. Dept. Agr., Farmers' Bui. 850 (1911), pp. 15, figs. 7).— Full direc- 

 tions are given for making cottage cheese from skim milk on the farm, with 

 and without the use of pepsin or rennet, in small quantities for home use and 

 on a larger scale for marketing. 



VETERINARY MEDICINE. 



Veterinary obstetrics, W. L. Williams (Ithaca, N. T.: Author, 1917, pp. 

 ZIV+637, pis. 3, figs. 14O). — This is the first of two volumes of which the 

 second will relate to associated diseases. This volume is based upon the work 

 previously noted (E. S. R., 21, p. 579), which has been rewritten and rearranged 

 upon an entirely new plan. 



Report of the veterinary department for the biennial period ended June 

 30, 1916, J. I. Gibson (Bien. Rpt. Vet. Surg. Iowa, 10 (1915-16), pp. 3Jf).— In 

 addition to a short history of the general outbreak of foot-and-mouth disease 

 throughout the country, by J. R. Mohler, a detailed statement of the outbreak 

 in Iowa in 1914^-15 is given, together with notes on the eradication work with 

 hog cholera through sanitary measures, on dourine, etc. 



A plea for the standardization of reports of agglutination tests, P. B. 

 Hadley (Jour. Immunol., 2 (1917), No. 5, pp. 463-467). — The author, at the 

 Rhode Island Experiment Station, proposes the following scheme for records 

 and for publication of results of agglutination tests: 



" That a complete flocculation and clearing, so that the medium becomes water- 

 clear, be referred to as a complete agglutination, and be expressed by the 

 symbol (C). That the last tube, beyond which no significant agglutination can 

 be observed, be regarded as an agglutination of grade 1, and be expressed by the 

 symbol (1). That between these two extreme grades of reaction there be re- 

 corded, if present, three intermediate grades expressed by the symbols (4), (3), 

 (2) .... That a negative test (i. e., no appreciable agglutination) be expressed 

 by the zero sign (0). That when no test is made in a certain dilution for a cer- 

 tain antigen, this circumstance be expressed by the minus sign or blank 

 ( — ) .... That statements regarding the degrees of sedimentation in the con- 

 trol tube should always be reported in a ' control column.' That the smallest 

 detectable quantity should be regarded as a trace of sediment, and expressed 

 by the symbol (T). That a significant sedimentation . . . should be expressed 

 by the symbol (S). That such a degree of sedimentation as might perhaps 

 invalidate the test should ... be expressed by the symbol (SS)." 



It is indicated that such a system for recording and expressing results would 

 eliminate much confusion in interpretation and render the tests of different 

 workers comparable to a much greater degree than is possible at the present 

 time. 



Studies in anaphylaxis. — XX, The reciprocal relations of antigen and 

 antibody within the cell, — A contribution to cellular immunology, R. Weil 

 (Jour. Immunol., 2 (1917), No. 5, pp. 469-499, fig. i ) .—Continuing the studies 

 previously noted (E. S. R., 36, p. 677), data are submitted which further es- 

 tablish the previously made contention of the coexistence of antigen and anti- 

 body within the cell and also the influence that these two factors exert upon 

 each other in the cell. 



"When guinea pigs are passively sensitized by the injection of rabbit im- 

 mune serum, quantitative studies show that the anchored, or cellular, antibody
