blood poisoning from three to four days after the operation, they are 

 not included in the following tables. 



Of the sixteen dogs which surged the operation — from the day 

 after both their thoracic and bile ducts were ligatured — eight passed 

 urine containing neither bile pigment nor bile acid. In all of these 

 cases the thoracic and common bile ducts had been ligatured at the 

 same time.

In the remaining eight cases the thoracic duct was ligatured some 

 days after the common bile duct, and in them the bile pigment and 

 bile acid, which had appeared in the urine as soon as the bile duct 

 was ligatured, disappeared from it on the thoracic duct being also 

 operated upon, except in those cases where a sufficient time had 

 been allowed to elapse after the two operations to admit of collateral 

 lymphatics being formed.
