The first law of protoplasm has been accepted 

 for over fifty years. (See page 13.) It has al-

 limited to a study of man, little would even now be 

 known. Simpler animals can be studied and all 

 of the steps in reproduction recorded because a 

 large number of the stages take place either out- 

 side of the parent or in organs easily prepared for 

 observation. 



We all recognize that a clear understanding of 

 this basal law has an important bearing upon our 

 happiness. So little information is actually avail- 

 able except to the technical scientist that this phase 

 of man's education has long been deficient through 

 no fault of his own. 



In any explanation of the application of this 

 law, it is easier to begin the study with the con-

 leave the specific application to man for a separate 

 discussion.
