PLATE XVIII. DISTRIBUTION OF FINE NERVE FIBRES TO 

 CAPILLARY VESSELS. 



Connective tissue covering part of the mylohyoid muscle of the frog, and extending 

 from its posterior portion, showing capillaries and nerve-fibres distributed to them. 

 a, Capillary vessels, with their nerve-fibres. 6, Bundles of fine dark bordered nerve 

 bres, from -which fine nerve-fibres may be traced to the capillaries, as well as to their 

 distribution in the connective tissue, where they form networks of exceedingly fine 

 compound fibres. The engraving represents the specimen as if magnified only 110 

 diameters, but the original drawing was taken from it when placed under a much 

 higher power. The specimen was mounted in 1863, and still (1872) demonstrates the 

 points represented in the-drawing, p. 308.
