It is therefore not necessary to assume the local formation of 

 antibodies in order to account for the active sensitization of 

 pulmonary tissues.

The role of hepatic tissue in anaphylaxis. 



By W. H. Manwaring and Harold E. Crowe. 



[From the Department of Bacteriology and Experimental Pathology, 

 Leland Stanford Jr. University.] 



If 0.25 per cent, goat serum in 50 per cent, defibrinated normal 

 blood is repeatedly perfused through the liver of a normal guinea 

 pig, a slight reduction in the toxicity of the perfusion fluid is 

 usually observed, on subsequent tests with isolated anaphylactic 

 lungs. In no case, however, is the reduction in toxicity sufficient 

 to prevent the anaphylactic reaction in these lungs. 



If the liver of an anaphylactic guinea pig is similarly perfused, 

 the perfusion fluid usually becomes almost completely non-toxic 

 for anaphylactic lungs. 



This reduction in toxicity is not accompanied by a measur- 

 able decrease in the amount of goat protein in the perfusion fluid, 

 as determined by a subsequent titration with a specific precipitin.

The food value of soy bean products. 



By Thomas B. Osborne and Lafayette B. Mendel. 



[From the Laboratory of the Connecticut Agricultural Experiment 

 Station and the Sheffield Laboratory of Physiological Chem- 

 istry in Yale University, New Haven, Connecticut.] 



Soy beans fed as the sole source of protein, or as a supplement 

 to corn gluten, are suitable for the nutrition of rats. They con- 

 tain sufficient water-soluble vitamine to promote normal growth; 

 for diets containing soy bean flour, butter fat, starch, and an 

 artificial salt mixture have promoted growth as well as com- 

 parable rations containing natural protein-free milk. The pres-
