206 PHYSIOLOGY AT THE FARM. 



took out, with considerable difficulty, an ounce only of gastric 

 juice, and that not very pure : some yellow bile came mixed 

 with the latter portions. Temperature of the stomach, 99 ; 

 atmosphere, 28. He breakfasted at nine o'clock on corn and 

 wheat bread, butter, and coffee. 



"At 10.45 examined, and took out a portion food partly 

 digested a few small particles to be seen stomach full of 

 fluids, with a thin pellicle of oil on the top. Temperature of 

 stomach, 1 00. At twelve o'clock A.M. stomach full of fluids 

 digestion not complete particles of bread floating about in a 

 pulpous state oil floating on the surface. At 12.30 A.M. 

 examined contents of stomach half diminished distinct 

 particles of oil on the surface. At 12.45 entire particles of 

 bread yet to be seen quantity of fluid diminishing. At 1 P.M. 

 distinct particles of bread still floating; fluid less. At 1.15 

 P.M. stomach empty. 



" Remarks. Some indications of gastric derangement this 

 morning small aphthous patches on the mucous membrane 

 juice acrid and sharp, with bile mixed with it." * 



Subjoined are examples taken from Beaumont's table of the 

 periods of time required respectively for natural digestion in 

 the stomach,, and for artificial digestion with gastric juice 

 collected from the stomach, in the case of various vegetable 

 substances. It should be premised, that in artificial digestion 

 one ounce of gastric juice was as near as possible employed 

 for each drachm of aliment. Rice, boiled, required for diges- 

 tion in the stomach one hour. Apples, sweet, mellow, raw, 

 required for digestion in the stomach an hour and a half; in 

 the artificial process, six hours and forty-five minutes. Sago, 

 boiled, stomach, one hour and forty-five minutes ; vial in 

 sand-bath, three hours and fifteen minutes. Tapioca, boiled, 

 stomach, two hours ; vial, three hours and twenty minutes.
