EXCRETORY BILIARY PASSAGES. 2:t5 



ducts been filled by injection and their connection with the 

 interlobular ducts apparently established, they have been 

 observed filled with inspissated bile in icteric livers. 1 A 

 method of study, very ingenious and highly satisfactory in 

 its results, was adopted by Chrzonszczewsky. He intro- 

 duced into the blood-vessels or stomach of a living animal a 

 solution of indigo-carmine, and within one or two hours, 

 killed the animal, when the whole net-work of ducts in the 

 lobules was found unbroken and connected with the inter- 

 lobular vessels. The drawings of these appearances accom- 

 panying the memoir are exceedingly beautiful.* 



A peculiarly favorable opportunity for observing the 

 bile-ducts in the lobules was presented in the livers of ani- 

 mals that died of the so-called " Texas cattle-disease." This 

 was taken advantage of by Dr. R. C. Stiles, who was able 

 to verify, in the most satisfactory manner, the facts which 

 have lately been established by the German anatomists. 3 In 

 these livers, the finest bile-ducts were found filled with bright 

 yellow bile, and their relations to the liver-cells were beauti- 

 fully distinct. In the examination of these specimens, the 

 presence of what appeared to be detached fragments of these 

 little canals is an argument in favor of the view that they 

 were lined by a membrane of excessive tenuity. These in- 

 teresting anatomical points were demonstrated by Dr. Stiles 

 before the Xew York Academy of Medicine, and we have 

 since been able to verify them in every particular. 



Anatomy of the Excretory Biliary Passages. There 

 can be scarcely any doubt of the connection between the in- 

 tercellular biliary plexus in the substance of the lobules and
