Needless to say, these averages, made from' such a range of 

 \ariation, are worthless. It is evident that no general conclusions 

 can be drawn from material so discrete. I have plotted these vocab- 

 ularies repeatedly in many different arrangements, and no norm or 

 n-edian appear, no curve of any recognizable type presents itself. 

 Evidently a rnuch larger number of cases must be gathered before 

 it is po^silile to estab'ish standards of normal variations. At pres- 

 ent the most that can be said is, that of the fifty-one vocabularies, 

 m.ore than half (twenty-eight in all) range from no words to 

 thirty-six words. Of theso twenty-eight, only three contain more 

 than twenty-five words.
