KXPKUT.ArKN'l'S ON DIGESTION. 
stomach contained a greyish chyme, which strongly reddened the 
turnsol. The stomach of another to whom some cooked beef and 
spelt-bread and plenty of milk were given, and who died three 
hours and a half after the operation, was filled with softened mor¬ 
sels of meat and bread. AVhen rubbed, a sort of boidllie proceed¬ 
ed from them. The milk was coagulated. A turbid fluid, pro¬ 
duced by the dissolution of the food, reddened the tincture of turn- 
sol. 
As to the matters contained in the filtered fluid of the stomach, 
and of which chemical analysis indicated the presence, they were 
the same as were found in the stomachs of dogs that had not under¬ 
gone this operation. 1. A free acid; 2. Albumen, but in a con¬ 
siderable quantity only in the stomach of a dog that had been fed 
on meat, and only in a small quantity, and scarcely to be detected, 
in others ; 3. A matter precipitable by the chloruret of tin. In none 
did we find any matter precipitable by acids, and not at the same 
time precipitable by boiling. The salts obtained by incineration of 
the fluids of the stomach were much chloruretted, little sulphuret¬ 
ted, and no carburetted or phosphuretted alkalies, and also some 
phosphate and carbonate of lime. 
It resulted from this, that the process of digestion in the stomach 
into which no bile could enter was the same as where the ductus 
choledochus had been tied. This conclusion perfectly accords with 
the result of the experiments of Brodie. We cannot, then, believe 
that the bile takes any direct part in the stomachic digestion, and 
we must reject as erroneous the opinions of those physiologists Avho 
maintain that a part of the bile ascends into the stomach, and is 
necessary to the completion of digestion. 
9. The state of the small intestines. 
A. In dogs that had fasted. —The small intestine of the dog 
that died on the 7th day after the operation contained a liquid of a 
dirty yellow colour, Avith some portions of brown and grey mucus. 
The tincture of turnsol was a little reddened in the second division 
of the stomach, but it was not at all in the first. The contents of 
the small intestine of the dog who perished three days after the 
operation were of the same character, except that they had no action 
on the turnsol. In the dog that was killed, fasting, four days after 
the ligature, Ave found in the superior part of the small intestine a 
small quantity of thick mucus, and in the inferior portion a liquid 
houillie of a white broAvn colour ; neither the one nor the other had 
any action on the turnsol. 
B. In dogs that had eaten. —The first half of the small intes¬ 
tine of the dog that had been fed on roast pork presented some 
grey mucous flocculi, Avhich very feebly reddened the turnsol. 
The second half contained a firm, Avhite, opaque, mucous boidlie,
