350 ENDOCRINE GLANDS 



Hallion has particularly insisted on this point. "There 

 certainly exist a number of specific cellular products. These 

 are at least as many as there are organs: The color, the 

 characteristic smell of each organ, which superimposes 

 itself in mammals to the smells of the zoological species- 

 would be sufficient to prove this, without speaking of the 

 physiological effects which investigators have found in a 

 certain number of these extracts. There are also in some 

 organs, if not in all, several specific substances." 



This alone would allow us to believe that there are 

 certain determined properties which are specific to certain 

 organs and which may be taken advantage of in therapeu- 

 tics, just as this is done in the case of certain plants. It 

 is not, however, from this idea that organo therapy, as we 

 understand it to-day, was born; it emanates from the con- 

 ception of the internal secretions of Claude Bernard and 

 particularly to its generalization by Brown-Sequard. 



We know how this celebrated physiologist reaches the 

 conclusions that not only certain glands, but the greatest 

 variety of organs were able to elaborate, within their cells, 

 certain substances which were afterwards poured in the 

 blood stream. Each one of these products has a defi- 

 nite action on other organs. These products are specific 

 in different ways. By their origin, as they come from one 

 well-defined organ, by their chemical composition and by 

 their physiological action. 



From this conception we see that the absence or defi- 

 ciency of a certain organ, results in the deficit of one or 

 more useful substances, often absolutely necessary. The 

 rational procedure in this case would be to introduce in 

 the organism these substances which are missing. The 

 logical way to obtain these substances would naturally be 

 in similar healthy organs. 



As we introduce into the gastro intestinal tract pepsin,
