PLATE XVIII.— DISTRIBUTION OF FINE NERVE FIBRES TO 

 CAPILLARY VESSELS. 



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

 from. Its posterior portion, showing capillaries and nerve-fibrea distributed to them, 

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

 f bres, from vrhich fine nerve-fibres xnay be traced to the capillaries, as -well as to their 

 distribution in the connective tissue, vrhere they form netv7orks of exceedingly fine 

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

 dianrieters, but the original drawing was taken frona it -when placed under a much 

 higher pov7er. The specimen was mounted in 1863, and still (1872) demonstrates the
