INFANTILISM 859 



true endocrine-glandular origin and the other of dystrophic nature. Falta, 

 Mathes, Bauer and others restrict the term to the dystrophic forms, recog- 

 nizing transitional or combination forms, but ruling out entirely the 

 primary ductless glandular diseases. Whether the first or the latter con- 

 ception will finally prevail, I consider it justifiable to include both in my 

 discussion for historical reasons and for the purpose of demonstrating 

 the points of issue and the ramifications of the subject; this plan also 

 regards the didactic advantages accruing from a broader comprehension 

 of the subject.
