Conclusion 



The literature as a whole affords little or no reliable evidence that 

 the thymus has any true endocrin function. In all probability the organ is 

 of significance in the physiological and pathological processes merely by 

 virtue of its lymphoid character. Whatever function it has probably is 

 concerned with the defensive mechanisms against infections. Such an 

 aspect of thymus function obviously does not fall within the purview 

 of this work.
