The venous apparatus of the digital region is remarkable 

 for the number, distribution and interlaced disposition of the 

 vessels composing it. They are extended over and molded

 flexiform nets and arches, and communicating with each other, 

 or traversing every elemient, by an intricate system of arte- 

 rioles or venules, analogous to the capillary system.
