30.77 per cent left, a difference in favor of the right of 5.76 per 

 cent, table 6. Of the 56 plexuses from the right side that \Aere 

 studied, 19 are in group 2, or 33.92 per cent, and of the 58 plexuses 

 from the left side, 16 or 27.58 per cent are in this group. This 

 gives a difference of 6.34 per cent in favor of the right side. 



There are but 3 plexuses from white females in group 2, as 

 against 14 from colored females. This gives a difference in per- 

 centage occurrence of over 21, table 2. Of the 20 plexuses from 

 white females studies, 3 are in group 2, or 15 per cent, while 14 

 of the 41 plexuses from colored females are in this group, or 34.41 

 per cent. . This gives a difference in favor of the colored of 19.14 

 per cent. 



Nine of the 52 plexuses of group 2 are from the right side of 

 female subjects and 8 from the left side, or 17.30 per cent and 

 15.38 per cent of the group respectively. Of the 31 plexuses 

 from the right side of female bodies that were studied, 9 or 29.03 

 per cent are in group 2 and of the 30 from the left side, 8 are in 

 this group, or 26.66 per cent, a difference in favor of the right of 

 2.37 per cent. 



Upon the right side there are 28 plexuses in group 2, that is, 

 53.84 per cent of the group, and upon the left side there are 24, 

 or 46.15 per cent. There are 28 right plexuses in group 2 out of 

 a total of 87 rights or 32.18 per cent, and out of a total of 88 left 

 plexuses 24 fall into group 2 or 27.27 per cent which shows that 

 in this series, group 2 plexuses are found 4.91 per cent more often 

 - on the right side. 



About three-fifths of the plexuses in group 2 are from colored 

 and two-fifths from white subjects. Table 3 shows that 21 or 

 40.38 per cent of the group are from white subjects and 31 or 

 59.61 per cent are from colored subjects. Twenty-one of the 

 85 plexuses from white bodies or 24.70 per cent, and 31 out of 

 90 from colored bodies or 34.44 per cent are in group 2. It 

 would appear then that this group of plexuses is 9.74 per cent 

 more common in colored than in white subjects. 



The 21 plexuses from white subjects are 18 from males and 3 

 from females. Comparing this with the total number from white 

 males, 65, and from white females, 20, we have 27.69 per cent
