Note. — ^A considerable range in kind and degree of behavior will be noted in the foregoing 

 list; in a few cases the classification may be said to be in doubt, but in such cases it is (for the 

 testing of the hypothesis) itnmaterial. Taking all things into consideration, the assigned 

 classification seemed the most reasonable. 



5. CONCLUSION. 



It is morally certain that temperament in man is "determined" by 

 a pair of hereditary, germinal factors, namely, a factor for excitation 

 whose allelomorph is absence of excitation or placidity; and a factor 

 for normal cheerfulness whose allelomorph is absence of cheerfulness 

 or depression; that these factors may be inherited independently of 

 each other; that dominance is ordinarily imperfect, so that two doses 

 of a factor give a more pronounced result in the offspring than only 

 one dose ; that (with rare exceptions) the offspring of two manic parents 

 are excitable ; of two placid parents are not excitable; of a depressed and 

 a non-depressed are not depressed ; of two depressed are all depressed.
