to the capillary ; and there are two important facts 

 brought out to which I wish to call special attention: one 

 is that the nerves are centrifugal, or motor nerves ; the 

 other, that the'capillaries have a direct nerve supply, and 

 that the nerves which we find in connection with them 

 are not simply the continuation of those supplying the 

 larger vessels (arteries and veins). 



These nerves are very fine, but show little expansions

 at short intervals, where they are in absolute contact 

 with the vessel, which expansions one might consider as 

 a sort of end plate. I have also observed repeatedly 

 that cross branches are given off, at times a number close 

 together, but I cannot decide whether these entwine the 

 vessel or end in little plates. These nerves are very easy 

 to overlook and often can only be recognized by their 

 nuclei, which form a protrusion on the outline of the 

 capillary, being situated, of course, on the outside of the 

 vessel. It is very common for a pair of such fibres to 

 run along on a capillary. One must, of course, not 

 confound these nerve-fibres with those running along- 

 side of the capillary, and which can be seen readily. The
