A. Artery. 



B, B. Nerve-trunks. 



c, c. Ganglia (i, and ii). 



a. The place where the nerve-trunks disappear in the ad -

 e f. Transverse line at which the nerve-trunk from ganglion i 

 is supposed to be interrupted. 

 Bj and Bj. Nerve-trunks which ought to be continuous with each 



other, and to connect the ganglia i and ii together . 

 DD. Capillaries. 



4. — Nerve-trunk arising from ganglion ii of fig. 3, and supplying the artery 

 A of the same figure. Hartnack, No.. 2. 



A. Artery. 



B. Nerve-trunk. 



a. Nerve-fibres ending in the artery. 

 D. Capillaries. 



5. — From the bladder of a dog stained with chloride of gold. Hartnack, 

 No. 5. 

 A. Artery. 



Bj andcj. Nerve-trunks arising from ganglia situated close 

 together on a nerve-trunk not shown in the figure. 



a. Nerve -fibres ending in the ad ventitia. 



6. — Ganglion situated on a large nerve-trunk, with smaller accessory
