The existence of both arterial and venous retia intimately associated together 

 is explained by the hypothesis tbat the gland secretes this substance into the 

 capillaries passing tbrough it, and owing to tbe intimate association of the 

 arterial and venous retia it diffuses into the vessels of the arterial rete and 

 causes disintegration of the red corpuscles before they reach the gland. The 

 oxygen so liberated is taken up by the gland and secreted into the bladder. 

 Evidence for this Suggestion is given, and a method described for observing 

 the production of gas-bubbles from the gland-cells. [The author has modified 

 this hypothesis in a subsequent communication in the Anat. Anzeiger. Ref.]

Author's conclusions: 



The experiments demonstrate a parallelism between the original Bordet- 

 Genou fixation reaction which takes place with a known specific antigen and 

 its antibody, and the Wassermann reaction for Syphilis produced by a mix- 

 ture of serum from a syphilitic with various lipoidal substances (non-specific 

 antigen). 



On the two series of experiments dealing on the one band with the 

 reaction between a serum and its specific antiserum (two combinations given), 

 and on the other between syphilitic serum and aqueous Solution of syphilitic 

 liver, alcoholic extract of syphilitic liver, lecithin, a perfect analogy is found 

 in respect to variations in the amount of either reacting substance. It is 

 found that a given degree of alexin fixation takes place when either antigen 

 (vel non-specific antigen) or antibody is decreased, provided the other reacting 

 substance is correspondingly increased. This would indicate that the fixing 

 complex in both instances is formed in varying proportions.

(Univ. of Calif. Pub. in Pathology 2,1. p. 1—22. 1911.) 

 A series of experiments is described with tabulated data and the con- 

 clusion drawn that „alexin fixation by a mixture of serum and antiserum is 

 produced by an antigen-antibody complex distinct from precipitinogen-preci- 

 pitin but usually brought down by the precipitate in its formation in such a 

 way as to give the appearance that fixation is produced by the precipitate 

 itself. It would seem then that Genou's original supposition, without direct 

 proof of antialbuminous sensitizers more correctly explains this type of the fixation 

 reaction. The best expression of the conditions as they seem to exist would 

 be found in Nicolle's hypothesis, who concludes that antisera contain two 

 classes of antibodies, ,coagulins' and ,lysins'; the former, as in this particular 

 instance, producing precipitation, and the latter, the fixation reaction."
