11 immunity " is but a state of latent poisoning awaiting 

 correction by some kind of costly elimination, if it is not to 

 lead to rank degeneration. For, as Prof. Richet explains 

 "without difficulty," "there are formed simultaneously in the 

 blood antitoxins for immunity and toxigens for anaphylaxis." 

 If the blood is thus becoming laden with all possible 

 poisons, antitoxins for neutralisation purposes, and toxigens 

 for eliminative purposes, how is it to perform its usual and 

 normal functions? How is it to maintain a desirable degree 

 of vitality and of resistance in other directions? Once more, 

 happy the dog that gets rid of "immunity." Happy he also 

 that dies of anaphylaxis. 



For whoso lives, as I, in many woes 

 How can it be but death shall bring him gain ? 



Immunity or anaphylaxis is observed according to the strength of 

 the exciting injection, immunity following weak doses and anaphylaxis 

 following strong doses. 



In other words, as I have already apprehended, with 

 weak doses the body is content to continue the neutralising 

 process rather than risk a supreme crisis. But with a strong 

 excitation it is forced to react violently. 



The fact that " there are very great individual differences 

 in the sera of animals treated in exactly the same manner," 

 again shows that the constitutional differences between various 

 individuals are many, and that, hence 



Eines schickt sich nicht fur Alle. 



"Passive anaphylaxis" (i.e., as I would say, latent 

 poisoning, unrelieved by an eliminative crisis) " has been 

 observed in the dog, the rabbit, and guinea-pig. In the dog it 

 does not merely manifest its presence by immediate effects, but 

 also by chronic secondary effects. Occasionally the dog is not 

 very ill after the exciting injection ; nevertheless it dies sooner 

 than a normal dog and as the result of weaker doses." 



It is precisely these "chronic secondary effects " which, in 

 my opinion, are so important. Obviously they indicate that a 

 general pauperisation is the result of these injections, and that
