calities and for each of the six cortical layers. The locations 

 for the samples are shown in figure 2. 



The method and material was that used for the previous 

 study, but the unit volume in this latter instance is 100^^. Table 

 24 condensed from table 3 (Craigie, '21) last half, gives the 

 length of the capillaries in m. for this unit volume. At the same 

 time it gives the ratio of each of the values to that for the ventral
